Field data indicate that DBCP concentrations in ground water have decreased since the late 1970's. Laboratory experiments by earlier investigators show that DBCP transformed to 2-bromoallyl alcohol (BAA) under conditions similar to in situ conditions, with an estimated half-life ranging from 6.1 (pH 7.8, 21.1 degrees Celsius) to 141 years (pH 7.0, 15 degrees Celsius). For this current study, a detailed hydrogeologic investigation was done to assess the relative importance of chemical transformation, dispersion, and ground-water pumping and reapplication of irrigation water in affecting DBCP concentrations.\nGround-water samples were collected from 20 monitoring wells installed along a 4.6-kilometer transect. DBCP concentrations in these samples ranged from less than the detection limit of 0.03 mg/L to a maximum of 6.4 mg/L. Results of chlorofluorocarbon (CFC) age dating indicate that DBCP occurs in water that ranges in age from about 2 to 41 years. The primary transformation product BAA, which was identified during previous laboratory studies, was not detected at or greater than 0.03 mg/L in any of the 20 ground-water samples. The lack of detection of BAA indicates that transformation to BAA is insignificant relative to other processes controlling DBCP concentrations. Results from this current study indicate that the in situ hydrolysis half-life for DBCP to BAA is much greater than the laboratory-determined values.\nEstimated initial concentrations of DBCP, calculated using CFC-estimated travel times and a half-life of 6.1 years, indicate that maximum initial concentrations are consistent with maximum measured concentrations in ground water. In contrast to initial DBCP concentrations, the estimated initial nitrate concentrations indicate that nitrate concentrations in recharge water have increased with time.\nA conceptual two-dimensional numerical flow and transport modeling approach was used to test hypotheses addressing dispersion, transformation rate, and in a relative sense, the effects of ground- water pumping and reapplication of irrigation water on DBCP concentrations in the aquifer. The flow and transport simulations, which represent hypothetical steady-state flow conditions in the aquifer, were used to refine the conceptual understanding of the aquifer system rather than to predict future concentrations of DBCP. Results indicate that dispersion reduces peak concentrations, but this process alone does not account for the apparent decrease in DBCP concentrations in ground water in the eastern San Joaquin Valley. Ground-water pumping and reapplication of irrigation water may affect DBCP concentrations to the extent that this process can be simulated indirectly using first-order decay. Transport simulation results indicate that the in situ 'effective' half-life of DBCP caused by processes other than dispersion and transformation to BAA could be on the order of 6 years.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri994059","collaboration":"Prepared in Cooperation with the University of California - Davis","usgsCitation":"Burow, K.R., Panshin, S.Y., Dubrovsky, N.H., Vanbrocklin, D., and Fogg, G., 1999, Evaluation of processes affecting 1,2-dibromo-3-chloropropane (DBCP) concentrations in ground water in the eastern San Joaquin Valley, California: Analysis of chemical data and ground-water flow and transport simulations: U.S. Geological Survey Water-Resources Investigations Report 99-4059, viii, 57 p., https://doi.org/10.3133/wri994059.","productDescription":"viii, 57 p.","costCenters":[],"links":[{"id":157017,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":396040,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_19392.htm"}],"country":"United States","state":"California","otherGeospatial":"eastern San Joaquin Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119.736,\n              36.667\n            ],\n            [\n              -119.5370,\n              36.667\n            ],\n            [\n              -119.5370,\n              36.75\n            ],\n            [\n              -119.736,\n              36.75\n            ],\n            [\n              -119.736,\n              36.667\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5fabfc","contributors":{"authors":[{"text":"Burow, Karen R. 0000-0001-6006-6667 krburow@usgs.gov","orcid":"https://orcid.org/0000-0001-6006-6667","contributorId":1504,"corporation":false,"usgs":true,"family":"Burow","given":"Karen","email":"krburow@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":193930,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Panshin, Sandra Y.","contributorId":46126,"corporation":false,"usgs":true,"family":"Panshin","given":"Sandra","email":"","middleInitial":"Y.","affiliations":[],"preferred":false,"id":193932,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dubrovsky, Neil H.","contributorId":25193,"corporation":false,"usgs":true,"family":"Dubrovsky","given":"Neil","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":193931,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vanbrocklin, David","contributorId":55041,"corporation":false,"usgs":true,"family":"Vanbrocklin","given":"David","email":"","affiliations":[],"preferred":false,"id":193933,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fogg, Graham E.","contributorId":68779,"corporation":false,"usgs":true,"family":"Fogg","given":"Graham E.","affiliations":[],"preferred":false,"id":193934,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Several methodologies-including use of the Glover-Balmer equation, flood pulses, and channel permeameters- have been applied to this problem in the Middle Rio Grande Basin. In the work presented here, ground-water temperature profiles and ground-water levels beneath the Rio Grande were measured and numerically simulated at four sites. The direction and rate of vertical ground-water flux between the river and underlying aquifer was simulated and the effective vertical hydraulic conductivity of the sediments underlying the river was estimated through model calibration. </p><p>Seven sets of nested piezometers were installed during July and August 1996 at four sites along the Rio Grande in the Albuquerque area, though only four of the piezometer nests were simulated. In downstream order, these four sites are (1) the Bernalillo site, upstream from the New Mexico State Highway 44 bridge in Bernalillo (piezometer nest BRN02); (2) the Corrales site, upstream from the Rio Rancho sewage treatment plant in Rio Rancho (COR01); (3) the Paseo del Norte site, upstream from the Paseo del Norte bridge in Albuquerque (PDN01); and (4) the Rio Bravo site, upstream from the Rio Bravo bridge in Albuquerque (RBR01). All piezometers were completed in the inner-valley alluvium of the Santa Fe Group aquifer system. Ground-water levels and temperatures were measured in the four piezometer nests a total of seven times in the 24-month period from September 1996 through August 1998. </p><p>The flux between the surface- and ground-water systems at each of the field sites was quantified by one-dimensional numerical simulation of the water and heat exchange in the subsurface using the heat and water transport model VS2DH. Model calibration was aided by the use of PEST, a model-independent computer program that uses nonlinear parameter estimation. Mean vertical hydraulic conductivities were estimated by model calibration and range from 1.5x10<sup>-5</sup> to 5.8x10<sup>-6</sup> meters per second (m/s). Mean simulated vertical ground-water flux for the BRN02 piezometer nest is 3.30x10<sup>-7</sup> m/s; for the COR01 piezometer nest is 3.58x10<sup>-7</sup> m/s; for the PDN01 piezometer nest is 4.22x10<sup>-7</sup> m/s; and for the RBR01 piezometer nest is 2.05x10<sup>-7</sup> m/s. Comparison of the simulated vertical fluxes and vertical hydraulic conductivities derived from this study with values from other studies in the Middle Rio Grande Basin indicate agreement between 1 and 3.5 orders of magnitude for hydraulic conductivity and within 1 order of magnitude for vertical flux.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri994212","usgsCitation":"Bartolino, J.R., and Niswonger, R.G., 1999, Numerical simulation of vertical ground-water flux of the Rio Grande from ground-water temperature profiles, central New Mexico: U.S. Geological Survey Water-Resources Investigations Report 99-4212, iv, 40 p., https://doi.org/10.3133/wri994212.","productDescription":"iv, 40 p.","numberOfPages":"45","costCenters":[{"id":472,"text":"New Mexico Water Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":54859,"rank":299,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1999/4212/wrir994212.pdf","text":"Report","size":"346 kB","linkFileType":{"id":1,"text":"pdf"},"description":"WRIR 1999–4212"},{"id":124469,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1999/4212/report-thumb.jpg"}],"country":"United States","state":"New Mexico","geographicExtents":" {\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -108.3251953125,\n              32.731840896865684\n            ],\n            [\n              -103.447265625,\n              32.731840896865684\n            ],\n            [\n              -103.447265625,\n              36.03133177633187\n            ],\n            [\n              -108.3251953125,\n              36.03133177633187\n            ],\n            [\n              -108.3251953125,\n              32.731840896865684\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p><a href=\"mailto:%20dc_nm@usgs.gov\" data-mce-href=\"mailto:%20dc_nm@usgs.gov\">Director</a>, <a href=\"https://www.usgs.gov/centers/nm-water\" data-mce-href=\"https://www.usgs.gov/centers/nm-water\">New Mexico Water Science Center</a><br>U.S. Geological Survey<br>6700 Edith Blvd NE<br><span class=\"locality\">Albuquerque</span>,&nbsp;<span class=\"state\">NM</span>&nbsp;<span class=\"postal-code\">87113</span></p>","tableOfContents":"<ul><li>Abstract</li><li>Introduction</li><li>Methods and Field Observations</li><li>Numerical Simulation of Vertical Ground-Water Flux</li><li>Results and Discussion</li><li>Comparisons with other Work</li><li>Summary and Conclusions</li><li>References Cited</li><li>Supplemental Information</li></ul>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb191","contributors":{"authors":[{"text":"Bartolino, James R. 0000-0002-2166-7803 jrbartol@usgs.gov","orcid":"https://orcid.org/0000-0002-2166-7803","contributorId":2548,"corporation":false,"usgs":true,"family":"Bartolino","given":"James","email":"jrbartol@usgs.gov","middleInitial":"R.","affiliations":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"preferred":true,"id":195782,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Niswonger, Richard G. 0000-0001-6397-2403 rniswon@usgs.gov","orcid":"https://orcid.org/0000-0001-6397-2403","contributorId":197892,"corporation":false,"usgs":true,"family":"Niswonger","given":"Richard","email":"rniswon@usgs.gov","middleInitial":"G.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":465,"text":"Nevada Water Science Center","active":true,"usgs":true}],"preferred":true,"id":195783,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

For more extensive reviews of hurricane effects on coastal forests of the Caribbean and the southeastern United States, the reader is referred to issues of BioScience (1994, Vol 44, no. 4), Biotropica (1991, \"Special Issue: Ecosystem, Plant, and Animal Responses to Hurricanes in the Caribbean\", Vol. 23, No. 4, Part A) and the Journal of Coastal Research (1991, \"Impacts of Hurricane Hugo, Special Issue No. 8; and 1995, \"Imprcts of Hurricane Andrew on the Coastal Zones of Florida and Louisiana: 22-26 August 1992\", Special Issue No. 21). </p><p>Selected pertinent information from Virginia, South and North Carolina has been included in this review, because much of our knowledge of coastal forest response to hurricanes, salinity and flooding comes from the Atlantic coast. These areas are floristically similar to the northern Gulf of Mexico. Species distribution of coastal forest trees and shrubs on the Gulf of Mexico are listed in Appendix 1. </p><p>Extensive research has been conducted on the responses of individual tree species to increased salinity and flooding. Synthesis of this research, although very important for evaluating effects of sea-level rise and various hydrological modifications on coastal forest, is beyond the scope of this review. These studies are included as an annotated bibliography (Appendix 2). Selected field studies on tree responses to changes in hydrology and salinity (impoundments, drainage, etc.) are referenced in Appendix 3. </p><p>A review of mangrove response to sea-level rise is included in Chapter 2. Mangrove forests are discussed in the context of Holocene changes in geomorphology. Predictions of the fate of mangroves in the face of future sea-level rise, as well as a review of factors that affect interactions between mangroves and sea-level rise are discussed. Selected references from outside the United States are included, because much of our knowledge of how mangroves react to sea-level rise comes from other tropical areas of the world. A discussion of hurricane effects on the mangroves of south Florida highlights gaps in our knowledge of how hurricanes affect responses of mangrove vegetation to sea-level rise there. Mangrove responses to temperature and elevated CO2 are briefly mentioned. These factors, as well as sea level, are expected to change in the future and may affect mangrove distribution. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr99441","issn":"0094-9140","usgsCitation":"Williams, K., Pinzon, Z.S., Stumpf, R., and Raabe, E.A., 1999, Sea-level rise and coastal forests on the Gulf of Mexico: U.S. Geological Survey Open-File Report 99-441, 122 p., https://doi.org/10.3133/ofr99441.","productDescription":"122 p.","costCenters":[],"links":[{"id":154976,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0441/report-thumb.jpg"},{"id":51583,"rank":298,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0441/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc504","contributors":{"authors":[{"text":"Williams, Kimberlyn","contributorId":91527,"corporation":false,"usgs":true,"family":"Williams","given":"Kimberlyn","email":"","affiliations":[],"preferred":false,"id":187260,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pinzon, Zuleika S.","contributorId":72407,"corporation":false,"usgs":true,"family":"Pinzon","given":"Zuleika","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":187259,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stumpf, Richard P.","contributorId":193799,"corporation":false,"usgs":false,"family":"Stumpf","given":"Richard P.","affiliations":[],"preferred":false,"id":187257,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Raabe, Ellen A. eraabe@usgs.gov","contributorId":2125,"corporation":false,"usgs":true,"family":"Raabe","given":"Ellen","email":"eraabe@usgs.gov","middleInitial":"A.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":187258,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Mining operations have the potential to alter ground-water flowpaths and change the sources of water to pumped wells. Previous ground-water-flow modeling of the area has shown that water pumped from the supply wells is derived from infiltration from nearby rivers and surrounding bedrock. Some of that water flows through existing quarries. Because water quality differs among these sources and is affected by the path along which water flows to the wells, five flow conditions were simulated to evaluate the influence of different mining scenarios on sources of water as related to the size and shape of contributing recharge areas (CRAs) to wells. The first simulation was based on a revision of an existing model by Schalk (1996). The second and third simulations included one in which a 20-foot layer of undisturbed aquifer material within the quarry above the bedrock is left intact, and another in which the 20-foot layer is removed. The fourth and fifth simulations included one in which the 20-foot layer of undisturbed aquifer material is left above the bedrock and the quarry is backfilled with fine- grained sand and silt (a byproduct of the mining operations), and another in which the 20-foot layer is removed before the quarry is backfilled with the fine-grained sand and silt.\r\n\r\nThe results of the five model simulations indicate that the overall volumetric budgets among models change only slightly in response to changing conditions at the quarry. The most significant change is noted in the amount of water that the aquifers gained from constant head and river leakage. This change is due to the way the quarries were simulated and lower heads in the aquifers compared to those in simulations made with earlier models. Previously published model simulations showed that the 5-year CRAs did not extend into the area of the newest sand and gravel quarry. In this study, however, the size and shape of the CRAs differ in response to the addition of two supply wells, and the 5-year CRA for one of these wells intersects the sand and gravel quarry.\r\n\r\nParticle-tracking analysis indicates that the proportions of water from the principal water sources -- rivers, other quarries (excluding the quarry of interest), and bedrock -- stayed relatively constant among the model simulations. The number of particles that originate in the quarry of interest increased from about 1 percent of the total particles withdrawn through all wells when the 20-foot layer of undisturbed aquifer material was left intact, to 2 percent when the 20-foot layer was removed. In simulations in which the quarry of interest was filled with fine-grained sand and silt, the percentage of particles that travel through or originate in that quarry decreased to less than 1 percent of the total number of particles. Thus, the mining activities at the quarry of interest, combined with increased pumping at the two supply wells have only a small potential to change the overall water quality of water withdrawn from supply wells at the South Well Field.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/wri994136","usgsCitation":"Nalley, G.M., and Haefner, R.J., 1999, Simulation of the effects of nearby quarrying operations on ground-water flow at the South Well Field, Franklin County, Ohio: U.S. Geological Survey Water-Resources Investigations Report 99-4136, iv, 23 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri994136.","productDescription":"iv, 23 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":95730,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1999/4136/report.pdf","size":"7448","linkFileType":{"id":1,"text":"pdf"}},{"id":158941,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1999/4136/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f7e4b07f02db5f1e75","contributors":{"authors":[{"text":"Nalley, Gregory M. gmnalley@usgs.gov","contributorId":3674,"corporation":false,"usgs":true,"family":"Nalley","given":"Gregory","email":"gmnalley@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":true,"id":200499,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haefner, Ralph J. 0000-0002-4363-9010 rhaefner@usgs.gov","orcid":"https://orcid.org/0000-0002-4363-9010","contributorId":1793,"corporation":false,"usgs":true,"family":"Haefner","given":"Ralph","email":"rhaefner@usgs.gov","middleInitial":"J.","affiliations":[{"id":37947,"text":"Upper Midwest Water Science Center","active":true,"usgs":true}],"preferred":true,"id":200498,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The NHD is the culmination of recent cooperative efforts of the U.S. Environmental Protection Agency (USEPA) and the U.S. Geological Survey (USGS). It combines elements of USGS digital line graph (DLG) hydrography files and the USEPA Reach File (RF3). The NHD supersedes RF3 and DLG files by incorporating them, not by replacing them. Users of RF3 or DLG files will find the same data in a new, more flexible format. They will find that the NHD is familiar but greatly expanded and refined.\r\n\r\nThe DLG files contribute a national coverage of millions of features, including water bodies such as lakes and ponds, linear water features such as streams and rivers, and also point features such as springs and wells. These files provide standardized feature types, delineation, and spatial accuracy. From RF3, the NHD acquires hydrographic sequencing, upstream and downstream navigation for modeling applications, and reach codes. The reach codes provide a way to integrate data from organizations at all levels by linking the data to this nationally consistent hydrographic network. The feature names are from the Geographic Names Information System (GNIS).\r\n\r\nThe NHD provides comprehensive coverage of hydrographic data for the United States. Some of the anticipated end-user applications of the NHD are multiuse hydrographic modeling and water-quality studies of fish habitats. Although based on 1:100,000-scale data, the NHD is planned so that it can incorporate and encourage the development of the higher resolution data that many users require. The NHD can be used to promote the exchange of data between users at the national, State, and local levels. Many users will benefit from the NHD and will want to contribute to the dataset as well.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","publisherLocation":"Reston, VA","doi":"10.3133/fs10699","usgsCitation":"Water Resources Division, U.S. Geological Survey, 1999, The National Hydrography Dataset: U.S. Geological Survey Fact Sheet 106-99, 2 p., https://doi.org/10.3133/fs10699.","productDescription":"2 p.","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":124818,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/fs/1999/0106/report-thumb.jpg"},{"id":32080,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/1999/0106/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67b0ce","contributors":{"authors":[{"text":"Water Resources Division, U.S. Geological Survey","contributorId":128075,"corporation":true,"usgs":false,"organization":"Water Resources Division, U.S. Geological Survey","id":528625,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The study concentrated on cottonwood-willow woodlands (predominantly <i>Populus fremontii</i> and <i>Salix gooddingii</i>) and mesquite bosques (predominantly <i>Prosopis glandulosa</i>). Tree-growth characteristics were measured at 16 cottonwood-willow woodland sites and at 3 mesquite bosque sites. Density of live and dead trees, tree diameter and height, canopy density, live-crown volume, leaf-water potential, leaf-area index, mortality, and reproduction were measured or noted at each site. The sites included healthy and reproducing woodlands and bosques, stressed woodlands and bosques with no reproduction, and woodlands and bosques with high mortality. </p><p>Tree roots were studied at seven sites to determine the vertical distribution of the root system and their relation to the water table at healthy, stressed, and high-mortality cottonwood-willow woodlands. In the six trenches that were dug for this study in May 1997, no cottonwood roots were observed that reached the water table. The root systems of healthy trees typically ended 1 to 2 feet above the water table. At sites with high mortality, the main root mass was commonly 7 to 8 feet above the water table. </p><p>Water-table depth was monitored at each of the study sites. In addition, volumetric soil moisture and soil-water potential were monitored at varying depths at three cottonwood-willow woodland study sites and at two mesquite bosque sites. Ground, soil, river, lake, and plant (xylem sap) water were analyzed for concentrations of stable hydrogen and oxygen isotopes to determine the source of water used by the trees. </p><p>On the basis of the root-distribution, soil- and leaf-water potential, and isotope data, it was concluded that cottonwood, willow, and mesquite trees mainly rely on ground water for their perennial sustained supply of water. The trees mainly utilize ground water that has moved upward from the water table into the capillary fringe and into unsaturated soil nearer to land surface. Most precipitation (average is 4 to 6 inches per year) is lost by evaporation and by transpiration of shallow-rooted xeric plants, and very little reaches the root zone of trees along the Mojave River. </p><p>Water-table depth had no strong correlation to many individual tree-growth characteristics, such as density, diameter, height, and live-crown volume. However, leaf-area index (corrected for stem area) of both healthy and stressed cottonwood-willow woodlands had a highly significant statistical relation to water-table depth, and a curvilinear regression model was defined. As in cottonwood-willow woodlands, leaf-area index of mesquite bosques also decreased with increased water-table depth. However, because of the small number of sites, no significant statistical relation could be defined for mesquite bosques. Because it can be accurately measured repeatedly at the same locations, leaf-area index (corrected for stem area) is recommended as the primary growth characteristic that should be monitored. Future vegetation changes along the Mojave River can be quantified using the sites established for this study. </p><p>Mortality was as high as 39 percent in healthy cottonwood-willow woodlands, but mortality of 50 to 100 percent was common where water-table depth was greater than about 7 feet or in areas where permanent water-table declines greater than about 5 feet had occurred. At a healthy mesquite bosque where the water-table depth ranged from about 8 to 11 feet, mortality was about 20 percent. Where the water table had been lowered an additional 10 to 25 feet by pumping, mortality of the mesquite was extremely high (80 to 99 percent). </p><p>On the basis of observations of plant reproduction, it was concluded that established cottonwood-willow woodlands probably will reproduce, mainly by root sprouting of mature trees, if the water-table depth during spring and early summer is less than about 5 feet and if there is sufficient sunlight. Likewise, reproduction in established mesquite bosques will probably occur by root sprouting if the water-table depth during spring and early summer is less than about 8 feet. Germination of cottonwood and willow seeds is common during spring in dry channels following winter stormflows in the Mojave River. However, most of the seedlings die before their roots reach a perennial water supply near the water table, and established stands of trees resulting from seed germination are rare.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri994112","usgsCitation":"Lines, G.C., 1999, Health of native riparian vegetation and its relation to hydrologic conditions along the Mojave River, southern California: U.S. Geological Survey Water-Resources Investigations Report 99-4112, iv, 28 p., https://doi.org/10.3133/wri994112.","productDescription":"iv, 28 p.","costCenters":[],"links":[{"id":411743,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_22565.htm","linkFileType":{"id":5,"text":"html"}},{"id":159394,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1999/4112/report-thumb.jpg"},{"id":95711,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1999/4112/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","otherGeospatial":"Mojave River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -117.441,\n              35.062\n            ],\n            [\n              -117.441,\n              34.321\n            ],\n            [\n              -116.312,\n              34.321\n            ],\n            [\n              -116.312,\n              35.062\n            ],\n            [\n              -117.441,\n              35.062\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6ae4b07f02db63c880","contributors":{"authors":[{"text":"Lines, Gregory C.","contributorId":50502,"corporation":false,"usgs":true,"family":"Lines","given":"Gregory","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":199725,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This estimate is based on evaluation of three lines of evidence: (1) Streamflow measurements, which indicated that induced infiltration of river water near the well field averaged 0.67 cubic feet per second; (2) measurements of the rate of downward propagation of diurnal fluctuations in dissolved oxygen and water temperature at three piezometers, which indicated vertical Darcian flow velocities of 0.6 and 1.5 feet per day, respectively; and (3) chemical mixing models based on stable isotopes of oxygen and hydrogen, which indicated that 30 percent of the water reaching a well near the center of the well field was derived from the river. The estimated streambed-leakance values are compatible with other aquifer properties and with hydraulic stresses observed over a 2-year period, as demonstrated by a set of six alternative groundwater flow models of the Rockaway River valley. Simulated water levels rose 0.5 to 1.7 feet near the well field when simulated streambed leakance was changed from 0.2 to 0.6 feet per day per foot, or when a former reach of the Rockaway River valley that is now blocked by glacial drift was simulated as containing a continuous sand aquifer (rather than impermeable till). Model recalibration to observed&nbsp;water levels could accommodate either of these changes, however, by plausible adjustments in hydraulic conductivity of 35 percent or less.</p><p>The ground-water flow models incorporate a new procedure for simulating areal recharge, in which water available for recharge in any time interval is accepted as recharge only where the water level in the uppermost model layer is below land surface. Water rejected as recharge on upland hillsides is allowed to recharge aquifers at the base of the hillsides. Inclusion of uplands in models of valley-fill aquifers and use of the new procedure increases model complexity and data requirements, but automates the simulation of recharge to those aquifers from the uplands, even in transient-state simulations with multiple periods of varied stresses, and facilitates delineation of upland areas that contribute water to well fields. The area from which ground water flowed toward the Dover well field decreased with an increase in simulated streambed leakance or an increase in simulated hydraulic conductivity of upland till. </p><p>Concentrations of solutes in ground water near the Dover well field reflect the mixing of native ground water with water infiltrated from the Rockaway River. Chemical reactions in the aquifer, chiefly the weathering of carbonate minerals by dissolved carbon dioxide, affect the pH and the concentrations of both solutes and dissolved gases. Concentrations of sodium, chloride, and sulfate appear to be related to man's activities, such as road deicing, or to decay of organic matter in the aquifer. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri964068","usgsCitation":"Dysart, J.E., Rheaume, S.J., and Kontis, A.L., 1999, Induced infiltration from the Rockaway River and water chemistry in a stratified-drift aquifer at Dover, New Jersey, with a section on modeling ground-water flow in the Rockaway River Valley: U.S. Geological Survey Water-Resources Investigations Report 96-4068, 112 p., https://doi.org/10.3133/wri964068.","productDescription":"112 p.","costCenters":[],"links":[{"id":162339,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4068/report-thumb.jpg"},{"id":344534,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4068/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"New Jersey","city":"Dover","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f3e4b07f02db5ef64c","contributors":{"authors":[{"text":"Dysart, Joel E.","contributorId":42256,"corporation":false,"usgs":true,"family":"Dysart","given":"Joel","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":230581,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rheaume, Stephen J.","contributorId":50512,"corporation":false,"usgs":true,"family":"Rheaume","given":"Stephen","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":230582,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kontis, Angelo L.","contributorId":22809,"corporation":false,"usgs":true,"family":"Kontis","given":"Angelo","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":230580,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Trends were identified as constant levels and autoregressive components were computed at all wells on the basis of data collected from 1993 to 1997, using structural time series analysis. Fixed seasonal components were identified at 22 wells and outliers were identified at 23 wells. The 95- percent confidence intervals were forecast for water-levels during the first and second quarters of 1998. Intervals in the first quarter were consistent with 92.3 percent of the measured values. In the second quarter, measured values were within the forecast intervals only 65.4 percent of the time. Unusually low precipitation during the second quarter is thought to have contributed to the reduced reliability of the second-quarter forecasts. </p><p>Spatial interrelations among wells were investigated on the basis of the autoregressive components, which were filtered to create a set of innovation sequences that were temporally uncorrelated. The empirical covariance among the innovation sequences indicated both positive and negative spatial interrelations. The negative covariance components are considered to be physically implausible and to have resulted from random sampling error. Graphical modeling, a form of multivariate analysis, was used to model the covariance structure. Results indicate that only 29 of the 325 possible partial correlations among the water-level innovations were statistically significant. The model covariance matrix, corresponding to the model partial correlation structure, contained only positive elements. This model covariance was sequentially partitioned to compute a set of partial covariance matrices that were used to rank the effectiveness of the 26 monitoring wells from greatest to least. Results, for example, indicate that about 50 percent of the uncertainty of the water-level innovations currently monitored by the 26- well network could be described by the 6 most effective

A three-dimensional ground-waterflow and solute-transport model was developed and calibrated to evaluate the effects of remedial alternatives designed to reduce the magnitude and extent of a trichloroethylene plume in the water-table aquifer. The development of the model was based on the computer code HST3D, developed by the U.S. Geological Survey. Heads measured from February 1983 to April 1992 were used to calibrate the ground-water-flow component of the model. Trichioroethylene concentrations measured in ground-water samples in January 1990 and March 1992 were used to calibrate the solute-transport component of the model, which consisted in the calibration of the longitudinal and transverse dispersivities, the distribution coefficient, and the solute influx at the source of trichloroethylene. Model input values assigned to specific storage, dispersivity, net recharge rates, effective porosity, riverbed conductivity, horizontal and vertical hydraulic conductivities, initial heads and trichloroethylene concentrations, and the locations of specified-head, river-leakage, and no-flow boundaries are described in this report. The root mean square error of simulated water-table heads from the ground-water-flow component of the calibrated model was 0.81 foot. The root mean square error of the simulated trichloroethylene concentrations, from the solute-transport component of the calibrated model, was 29 micrograms per liter of trichloroethylene.<br></p><p>The four remedial alternatives simulated in this report were the revised Record of Decision, and alternatives A, B, and C. Remedial alternatives were simulated to study the movement of the trichloroethylene plume in the aquifer from March 1992 to March 2022, while wells located within the extent of the trichloroethylene plume pumped water at specified rates and depths at the prevailing trichloroethylene concentrations. The trichloroethylene mass in the Vega Alta water-table aquifer was estimated to be 12,984 and 12,814 pounds in January 1990 and March 1992, respectively. The solute influx to the aquifer was estimated to be 22 pounds per year under long-term net recharge rates. The trichloroethylene mass remaining in the aquifer was estimated to be 5,720 pounds in March 2022 after simulating the revised Record of Decision remedial alternative. The trichloroethylene mass remaining in the aquifer was estimated to be 5,194, 4,786, and 3,689 pounds in March 2022 after simulating remedial alternatives A, B, and C, respectively.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri974170","collaboration":"Prepared in cooperation with the Puerto Rico Industrial Development

The response of the ground-water system to an increase in withdrawal with no new sources of recharge was simulated to provide a baseline for comparing possible water-management plans and to determine their potential effects on wetlands in the area.\r\n\r\nTo assess the effects of additional withdrawal on the system, a 50-year-long stress period was added to the end of the existing three-dimensional, finite-difference, ground-water flow model. This stress period simulates recharge and discharge stresses determined for 1987-92. Another model was constructed by simulating 30 additional wells pumping a total of 4,000 acre-feet per year in the 50-year-long stress period. The 30 additional wells were simulated in a north-south trending line along the eastern part of the valley and as pumping from the bottom model layer.

In alpine areas of the Colorado Front Range, modest loadings of N in deposition have been associated with leakage of N to surface waters.
