This report presents precipitation and waterquality data from analyses of 210 samples collected at 30 storm-sewer outfall stations in the Dallas-Fort Worth area, Texas, during February 1992-November 1994. The data were collected to fulfill requirements mandated by the U.S. Environmental Protection Agency to the cities of Arlington, Dallas, Fort Worth, Garland, Irving, Mesquite, and Piano and to the Dallas and Fort Worth Districts of the Texas Department of Transportation to obtain a National Pollution Discharge Elimination System permit. Data were collected at storm-sewer outfall stations in drainage basins classified as singular land use, either residential, commercial, industrial, or highway. Also included are qualityassurance/quality-control data for samples collected in conjunction with the stormwater samples.

Borehole geophysical logs were run in selected wells; and the surficial, Black Creek, and upper Cape Fear aquifers were mapped. \r\n\r\nResults indicate that the surficial aquifer appears to have the greatest lateral variability of clay units and aquifer material of the three aquifers. A surficial aquifer water-level surface map, constructed from selected monitoring wells screened exclusively in the surficial aquifer, indicates the general direction of ground-water movement in this mostly unconfined aquifer is toward the Neuse River and Stoney Creek. However, water-level gradient data from a few sites in the surficial aquifer did not reflect this trend, and there are insufficient hydrologic and hydrogeologic data to determine the cause of these few anamalous measurements. \r\n\r\nThe Black Creek aquifer underlies the surficial aquifer and is believed to underlie most of Wayne County, including the Air Base where the aquifer and overlying confining unit are estimated from well log data to be as much as 100 feet thick. The Black Creek confining unit ranges in thickness from less than 8 feet to more than 20 feet. There are currently no accessible wells screened exclusively in the Black Creek aquifer from which to measure water levels. \r\n\r\nThe upper Cape Fear aquifer and confining unit are generally found at depths greater than 80 feet below land surface at the Air Base, and are estimated to be as much as 70 feet thick. Hydrologic and hydrogeologic data are insufficient to determine localized surficial aquifer hydrogeology, ground-water movement at several sites, or hydraulic head differences between the three aquifers.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr96581","issn":"0094-9140","usgsCitation":"Cardinell, A., and Howe, S.S., 1997, Hydrogeologic framework and ground-water resources at Seymour Johnson Air Force Base, North Carolina: U.S. Geological Survey Open-File Report 96-581, iv, 21 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr96581.","productDescription":"iv, 21 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":155239,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1996/0581/report-thumb.jpg"},{"id":52117,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1996/0581/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c463","contributors":{"authors":[{"text":"Cardinell, A.P.","contributorId":59033,"corporation":false,"usgs":true,"family":"Cardinell","given":"A.P.","email":"","affiliations":[],"preferred":false,"id":188637,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Howe, S.

Greater subsidence on the downthrown sides of faults contributes to more frequent flooding and generally wetter conditions, which are commonly reflected by changes in plant communities {e.g., Spartina patens to Spartina alterniflora) or progressive transformation of emergent vegetation to open water. Since the 1930s and 1950s, approximately 5,000 hectares of marsh habitat has been lost as a result of subsidence associated with faulting. Marsh- es have expanded locally along faults where hydrophytic vegetation has spread into former upland areas. Fault traces are linear to curvilinear and are visible because elevation differences across faults alter soil hydrology and vegetation. Fault lengths range from 1 to 13.4 km and average 3.8 km. Seventy-five percent of the faults visible on recent aerial photographs are not visible on photographs taken in the 1930's, indicating relatively recent fault movement. At least 80% of the surface faults correlate with extrapolated subsurface faults; the correlation increases to more than 90% when certain assumptions are made to compensate for mismatches in direction of displacement. Coastal wetlands loss in Texas associated with hydrocarbon extraction will likely increase where production in mature fields is prolonged without fiuid reinjection.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Coastal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Coastal Education and Research Foundation","usgsCitation":"White, W.A., and Morton, R.A., 1997, Wetland losses related to fault movement and hydrocarbon production, southeastern Texas coast: Journal of Coastal Research, v. 13, no. 4, p. 1305-1320.","productDescription":"16 p.","startPage":"1305","endPage":"1320","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":295582,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":295581,"type":{"id":15,"text":"Index Page"},"url":"https://www.jstor.org/stable/4298740"}],"country":"United States","state":"Texas","volume":"13","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"544775d6e4b0f888a81b835e","contributors":{"authors":[{"text":"White, William A.","contributorId":18293,"corporation":false,"usgs":true,"family":"White","given":"William","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":503663,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morton, Robert A.","contributorId":28184,"corporation":false,"usgs":true,"family":"Morton","given":"Robert","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":503664,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":27743,"text":"wri964198 - 1997 - Vulnerability of ground water to atrazine leaching in Kent County, Michigan","interactions":[],"lastModifiedDate":"2016-10-13T10:31:28","indexId":"wri964198","displayToPublicDate":"1997-10-01T00:00:00","publicationYear":"1997","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"96-4198","title":"Vulnerability of ground water to atrazine leaching in Kent County, Michigan","docAbstract":"A steady-state model of pesticide leaching through the unsaturated zone was used with readily available hydrologic, lithologic, and pesticide characteristics to estimate the vulnerability of the near-surface aquifer to atrazine contamination from non-point sources in Kent County, Michigan. The modelcomputed fraction of atrazine remaining at the water table, RM, was used as the vulnerability criterion; time of travel to the water table also was computed. Model results indicate that the average fraction of atrazine remaining at the water table was 0.039 percent; the fraction ranged from 0 to 3.6 percent. Time of travel of atrazine from the soil surface to the water table averaged 17.7 years and ranged from 2.2 to 118 years.
Three maps were generated to present three views of the same atrazine vulnerability characteristics using different metrics (nonlinear transformations of the computed fractions remaining). The metrics were chosen because of the highly (right) skewed distribution of computed fractions. The first metric, rm = RMλ (where λ was 0.0625), depicts a relatively uniform distribution of vulnerability across the county with localized areas of high and low vulnerability visible. The second metric, rmλ-0.5, depicts about one-half the county at low vulnerability with discontinuous patterns of high vulnerability evident. In the third metric, rmλ-1.0 (RM), more than 95 percent of the county appears to have low vulnerability; small, distinct areas of high vulnerability are present.
Aquifer vulnerability estimates in the RM metric were used with a steady-state, uniform atrazine application rate to compute a potential concentration of atrazine in leachate reaching the water table. The average estimated potential atrazine concentration in leachate at the water table was 0.16 μg/L (micrograms per liter) in the model area; estimated potential concentrations ranged from 0 to 26 μg/L. About 2 percent of the model area had estimated potential atrazine concentrations in leachate at the water table that exceeded the USEPA (U.S. Environmental Protection Agency) maximum contaminant level of 3 μg/L.
Uncertainty analyses were used to assess effects of parameter uncertainty and spatial interpolation error on the variability of the estimated fractions of atrazine remaining at the water table. Results of Monte Carlo simulations indicate that parameter uncertainty is associated with a standard error of 0.0875 in the computed fractions (in the rm metric). Results of kriging analysis indicate that errors in spatial interpolation are associated with a standard error of 0.146 (in the rm metric). Thus, uncertainty in fractions remaining is primarily associated with spatial interpolation error, which can be reduced by increasing the density of points where the leaching model is applied.
A sensitivity analysis indicated which of 13 hydrologic, lithologic, and pesticide characteristics were influential in determining fractions of atrazine remaining at the water table. Results indicate that fractions remaining are most sensitive to the unit changes in pesticide half life and in organic-carbon content in soils and unweathered rocks, and least sensitive to infiltration rates.
The leaching model applied in this report provides an estimate of the vulnerability of the near-surface aquifer in Kent County to contamination by atrazine. The vulnerability estimate is related to water-quality criteria developed by the USEPA to help assess potential risks from atrazine to the near-surface aquifer. However, atrazine accounts for only 28 percent of the herbicide use in the county; additional potential for contamination exists from other pesticides and pesticide metabolites. Therefore, additional work is needed to develop a comprehensive understanding of the relative risks associated with specific pesticides. The modeling approach described in this report provides a technique for estimating relative vulnerabilities to specific pesticides and for helping to assess potential risks.

The study was a cooperative effort between the U.S. Geological Survey (USGS) and the Oregon Department of Environmental Quality (ODEQ) and was coordinated with the USGS National Water-Quality Assessment (NAWQA) study of the Willamette River. Routing models are needed to estimate streamflow so that water-quality constituent loads can be calculated from measured concentrations and so that sources, sinks, and downstream changes in those loads can be identified. Runoff models are needed to estimate ungaged-tributary inflows for routing models and to identify flow contributions from different parts of the basin. The runoff and routing models can be run either separately or together to simulate streamflow at various locations and to examine streamflow contributions from overland flow, shallow-subsurface flow, and ground-water flow.
\nThe 11,500-square-mile Willamette River Basin was partitioned into 21 major basins and 253 subbasins. For each subbasin, digital data layers of land use, soils, geology, and topography were combined in a geographic information system (GIS) to define hydrologic response units (HRU's), the basic computational unit for the Precipitation-Runoff Modeling System (PRMS). Spatial data layers were also used to calculate noncalibrated PRMS parameter values. Other PRMS parameter values were obtained from 10 nearby calibrated subbasins of representative location and character.
\nAbout 760 miles of the Willamette River system were partitioned into 4 main-stem networks and 17 major tributary networks for streamflow routing. Data from time-of-travel studies, discharge measurements, and flood analyses were used to develop equations that related stream cross-sectional area to discharge and stream width to discharge. These relations were derived for all 21 stream networks at approximately 3-mile intervals and used in the Diffusion Analogy Flow model (DAFLOW) in streamflow routing.
\nTen representative runoff models and 11 network-routing models were calibrated for water years 1972-75 and verified for water years 1976-78. These were the periods with the most complete and widespread streamflow record for the Willamette River Basin. Observed and estimated daily precipitation and daily minimum and maximum air temperature were used as input to the runoff models. The resulting coefficient of determination (R2) for the representative runoff models ranged from 0.69 to 0.93 for the calibration period and from 0.63 to 0.92 for the verification period; absolute errors ranged from 18 to 39 percent and from 27 to 51 percent, respectively. Bias error for the runoff modeling ranged from + 13 to -32 percent. Observed daily streamflow data were used as input to the network-routing models where available, and simulated streamflows from runoff model results were used for ungaged areas. Absolute error for the network-routing models ranged from about 21 percent for the Molalla River model, for which 70 percent of the subbasin was ungaged, to about 4 percent for the Willamette main-stem model (Albany to Salem), for which only 9 percent of the subbasin was ungaged.
\nWith an input of current streamflow, precipitation, and air temperature data the combined runoff and routing models can provide current estimates of streamflow at almost 500 locations on the main stem and major tributaries of the Willamette River with a high degree of accuracy. Relative contributions of surface runoff, subsurface flow, and ground-water flow can be assessed for 1 to 10 HRU classes in each of 253 subbasins identified for precipitation-runoff modeling. Model outputs were used with a water-quality model to simulate the movement of dye in the Pudding River as an example

Numerous investigations have examined the growth of wetland tree species under a variety of hydrologic conditions. Most studies have compared flooded versus non-flooded conditions in greenhouses or in one to a few field sites near each other or within the same region. Comparisons of wetland tree growth among widely separated areas of the country are rare. This study compared the diameter growth of Nyssa sylvatica var. biflora, Nyssa aquatica, and Taxodium distichum trees from Louisiana (Gulf Coastal Plain) and South Carolina (Atlantic Coastal Plain). In both regions, individual trees were distributed along a gradient of hydrologic regimes from infrequent to permanent flooding. Nyssa sylvatica var. biflora was restricted to periodically flooded sites in both regions. Within these sites, this species showed little response to differences in mean water depth. In contrast, significant differences among hydrologic regimes were detected for N. aquatica in both regions. In Louisiana, patterns of growth response did not correlate with the gradient of hydrologic regimes, but in South Carolina maximum growth was inversely related to mean water levels during the growing season. Maximum growth of T. distichum trees was observed at sites with shallow, permanent flooding in both regions.

the temporal variability of atrazine in private well water. part ii: analysis of data","docAbstract":"In 1988, the Iowa Department of Natural Resources, along withthe University of Iowa, conducted the Statewide Rural WellWater Survey, commonly known as SWRL. A total of 686private rural drinking water wells was selected by use of aprobability sample and tested for pesticides and nitrate. A subsetof these wells, the 10% repeat wells, were additionally sampledin October, 1990 and June, 1991. Starting in November, 1991,the University of Iowa, with sponsorship from the United StatesEnvironmental Protection Agency, revisited the 10% repeat wellsto begin a study of the temporal variability of atrazine and nitratein wells. Other wells, which had originally tested positive foratrazine in SWRL but were not in the 10% population, wereadded to the study population. Temporal sampling for a year-long period began in February of 1992 and concluded in Januaryof 1993. All wells were sampled monthly, a subset was sampledweekly, and a second subset was sampled for 14 day consecutiveperiods. Of the 67 wells in the 10% population tested monthly,7 (10.4%) tested positive for atrazine at least once during theyear, and 3 (4%) were positive each of the 12 months. Theaverage concentration in the 7 wells was 0.10 µg/L. Fornitrate, 15 (22%) wells in the 10% repeat population monthlysampling were above the Maximum Contaminant Level of 10 mg/L at least once. This paper, the second of two papers on thisstudy, describes the analysis of data from the survey. The firstpaper (Lorber et al., 1997) reviews the study design, theanalytical methodologies, and development of the data base.

Contamination is also present at a municipal landfill in the City of Waterbury that is upgradient from the industrial sites in the local ground-water-flow system. The study area, which lies in the Western Highlands of Connecticut, is in the Mad River Valley, a tributary to the Naugatuck River. Geohydrologic units (aquifer materials) include unconsolidated glacial sediments (surficial materials) and fractured crystalline (metamorphic) bedrock. Surficial materials include glacial till, coarse-grained andfine-grained glacial stratified deposits, and postglacial floodplain alluvium and swamp deposits. The ground-water-flow system in the surficial aquifer is complex because the hydraulic properties of the surficial materials are highly variable. In the bedrock aquifer, ground water moves exclusively through fractures. Hydrologic characteristics of the crystalline bedrock-degree of confinement, hydraulic conductivity, storativity, and porosity-are poorly defined in the study area. Further study is needed to adequately assess ground-water flow and contaminant migration under current or past hydrologic conditions. All known water-supply wells in the study area obtain water from the bedrock aquifer. Twenty households in a hillside residential area on Tosun Road currently obtain drinking water from private wells tapping the bedrock aquifer. The extent of contamination in the bedrock aquifer and the potential for future contamination from known sources of contamination in the surficial aquifer is of concern to regulatory agencies. Previous investigations have identified ground-water contamination by volatile organic compounds at the Nutmeg Valley Road site area. Contamination has been associated with on-site disposal of heavy metals, chlorinated and non-chlorinated volatile organic compounds, and cyanide. Concentrations of volatile organic compounds detected in water samples collected from bedrock wells during 1981-95 at the Nutmeg Valley Road site area show a general downward trend through time. Water samples collected from wells completed in surficial materials were not collected systematically, and a trend in concentration cannot be identified.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nInformation Services [distributor],","doi":"10.3133/ofr97219","issn":"0094-9140","usgsCitation":"Stone, J.R., Casey, G.D., Mondazzi, R., and Frick, T., 1997, Preliminary hydrogeologic assessment of a ground-water contamination area in Wolcott, Connecticut: U.S. Geological Survey Open-File Report 97-219, iv, 29 p. :ill.

Ongoing analyses \r\nof the central portion of the Middle Rio Grande Basin by the U.S. \r\nGeological Survey (USGS) in cooperation with the City of \r\nAlbuquerque and other cooperators have shown that ground water in \r\nthe basin is not as readily accessible as earlier studies \r\nindicated. A more complete characterization of the ground-water \r\nresources of the entire Middle Rio Grande Basin is hampered by a \r\nscarcity of data in the northern and southern areas of the basin.\r\n\r\n The USGS Middle Rio Grande Basin Study is a 5-year effort by \r\nthe USGS and other agencies to improve the understanding of the \r\nhydrology, geology, and land-surface characteristics of the Middle \r\nRio Grande Basin. The primary objective of this study is to improve \r\nthe understanding of the water resources of the basin. Of \r\nparticular interest is to determine the extent of hydrologic \r\nconnection between the Rio Grande and the Santa Fe Group aquifer. \r\nAdditionally, ground-water quality affects the availability of \r\nwater supplies in the basin. Improving the existing USGS-\r\nconstructed ground-water flow model of the Middle Rio Grande Basin \r\nwill integrate all the various tasks that improve our knowledge of \r\nthe various components of the Middle Rio Grande water budget. Part \r\nof this improvement will be accompanied by extended knowledge of \r\nthe aquifer system beyond the Albuquerque area into the northern \r\nand southern reaches of the basin. Other improvements will be based \r\non understanding gained through process-oriented research and \r\nimproved geologic characterization of the deposits. The USGS will \r\nstudy the hydrology, geology, and land-surface characteristics of \r\nthe basin to provide the scientific information needed for water- \r\nresources management and for managers to plan for water supplies \r\nneeded for a growing population. \r\n\r\n To facilitate exchange of information among the many USGS \r\nscientists working in the Middle Rio Grande Basin, yearly technical \r\nmeetings are planned for the anticipated 5-year study. These \r\nmeetings provide an opportunity to present research results and \r\nplan new field efforts. This report documents the results of \r\nresearch presented at the first technical workshop held in Denver, \r\nColorado, in November 1996.\r\n\r\n The report is organized into this introduction, five chapters \r\nthat focus on USGS investigations in progress in the Middle Rio \r\nGrande Basin, and three appendixes with supplemental information. \r\nThe first chapter provides an overview of the USGS program in the \r\nbasin. The second chapter describes geographic data and analysis \r\nefforts in the basin. The third chapter details work being done on \r\nthe hydrogeologic framework of the basin. The fourth chapter \r\ndescribes studies on ground-water availability in the basin and is \r\ndivided into three areas of research: ground-water/surface-water \r\ninteraction, ground-water flow and aquifer properties, and \r\nrecharge. The fifth chapter is devoted to an overview of New Mexico \r\nDistrict Cooperative Program studies in the basin.

The ground-water-quality monitoring network within and immediately surrounding the research area consisted of 73 observation wells and 25 multiport wells. The primary objectives of the ground-water monitoring program at the Minnesota MSEA were to: (1) determine the effects of three farming systems on ground-water quality, and (2) understand the processes and factors affecting the loading, transport, and fate of agricultural chemicals in ground water at the site. This report presents well construction, geologic, water-level, chemical application, water-quality, and quality-assurance data used to evaluate the effects of farming systems on ground-water quality during 1991-95.

It examines the climatic and hydrologic data for evidence of trends. The hydrologic data examined includes total annual flow, base flow, and annual peak discharges.\r\nThis study was conducted to determine if there is evidence of trends present in hydrologic and climatic data. All available streamflow-gaging station data, with at least 10 or more years of record, were examined for trends. In addition, the data were divided into an 'early' period (ending in 1971), representing conditions before ground-water levels had declined appreciably, and a 'recent' period (1978-1994), reflecting the condition of declining ground-water levels, including the effects of storage reservoirs.\r\n\r\nTests for trend, moving averages, and comparisons of median and average flows for an early period (ending in 1971) with those for the recent period (1978-1994) show that the total annual volume of flow and the magnitudes of instantaneous annual peak discharges measured at most gaging stations in the Beaver- North Canadian River basin have decreased in recent years. Precipitation records for the panhandle, however, show no corresponding changes.\r\n\r\nThe changes in flow are most pronounced in the headwaters upstream from Woodward, but also are evident at Woodward and near Seiling, which represents the inflow to Canton Lake. The average annual discharge decreased between the early period and the recent period by the following amounts: near Guymon, 18,000 acre-feet; at Beaver, 68,000 acre-feet; at Woodward, 72,000 acre-feet; and near Seiling, 63,000 acre-feet. These decreases, expressed as a percentage of the average flows for the early period, were 91 percent near Guymon, 82 percent at Beaver, 49 percent at Woodward, and 37 percent near Seiling. The medians of the annual peak discharges decreased from the early period to the recent period by the following amounts: near Guymon, 98 percent; at Beaver, 86 percent; at Woodward, 80 percent; and near Seiling, 53 percent. The Guymon gage is not affected by reservoirs; the other three mainstem gaging stations are influenced by reservoirs, but the decreases in annual peak discharges are greater than can be explained by storage in those reservoirs.\r\n\r\nBase flows have undergone substantial change, but unlike the annual volumes the base flows show some increases and some decreases. Flow duration analyses show a shift in the distribution of annual flows. Less contribution is coming from large floods that formerly added substantially to the yearly average flows. Near Seiling, for example, the magnitudes of the large flows that occur less than about 20 percent of the time were greatly reduced in the recent period.\r\n\r\nA primary mechanism producing these decreased streamflows appears to be the depletion of ground water in the High Plains aquifer that underlies more than 90 percent of the basin. Changes in farming and conservation practices and in water use also may be having an effect.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri964304","usgsCitation":"Wahl, K.L., and Tortorelli, R.L., 1997, Changes in flow in the Beaver-North Canadian River basin upstream from Canton Lake, western Oklahoma: U.S. Geological Survey Water-Resources Investigations Report 96-4304, vi, 58 p., https://doi.org/10.3133/wri964304.","productDescription":"vi, 58 p.","costCenters":[],"links":[{"id":2458,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/wri964304/pdf/wri96-4304.pdf","linkFileType":{"id":5,"text":"html"}},{"id":124820,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_96_4304.jpg"}],"country":"United States","state":"Oklahoma","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -98.28223256564006,\n 36.366114435776524\n ],\n [\n -98.65668214895032,\n 36.55732225973237\n ],\n [\n -99.99994573352308,\n 36.98104291572069\n ],\n [\n -100.62402837237414,\n 36.91456402858782\n ],\n [\n -102.70430383520873,\n 36.890799658844145\n ],\n [\n -102.5735436632592,\n 36.54299803318963\n ],\n [\n -99.75625632216278,\n 36.50478711905258\n ],\n [\n -98.78149867672028,\n 35.659387111580685\n ],\n [\n -98.28223256564006,\n 36.366114435776524\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e2e4b07f02db5e4f0e","contributors":{"authors":[{"text":"Wahl, Kenneth L.","contributorId":61024,"corporation":false,"usgs":true,"family":"Wahl","given":"Kenneth","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":203052,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tortorelli, Robert L.","contributorId":65071,"corporation":false,"usgs":true,"family":"Tortorelli","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":203053,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":27293,"text":"wri964216 - 1997 - A method for evaluating water-level response to hydrologic stresses in karstic wetlands in central Florida, using a simple water-balance model","interactions":[],"lastModifiedDate":"2012-02-02T00:08:41","indexId":"wri964216","displayToPublicDate":"1997-09-01T00:00:00","publicationYear":"1997","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"96-4216","title":"A method for evaluating water-level response to hydrologic stresses in karstic wetlands in central Florida, using a simple water-balance model","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/wri964216","usgsCitation":"German, E.R., 1997, A method for evaluating water-level response to hydrologic stresses in karstic wetlands in central Florida, using a simple water-balance model: U.S. Geological Survey Water-Resources Investigations Report 96-4216, iv, 52 p. :ill., maps ;28 cm. +1 computer disk (3 1/2 in.)

All selected areas lie within a miogeoclinal belt where thick accumulations of carbonate rock followed by major episodes of compression and extension have greatly modified the region. Most of the selected hydrographic areas lie within the less extended terranes; however, several areas, or parts of areas, lie within severely extended terranes where carbonate rocks have been greatly thinned, or where deformed blocks of carbonate rock are discontinuous and isolated from surrounding carbonate rock aquifers. Three principal criteria were used to assess the development potential of each selected hydrographic area. These quantitative criteria are: (1) depth to water, (2) depth to and thickness of carbonate rocks, and (3) water quality. Other site-specific factors, such as accessibility and potential effects of ground-water development, are also discussed. Results suggest that sites with high potential for development may be scarce in southern Nevada. Many areas described as favorable on the basis of the three quantitative criteria were deemed unfavorable on the basis of possible short- and long-term effects associated with development and on the amount of available data used to make the assessment. The most favorable sites may be in more severely extended terranes, where development of isolated blocks (of carbonate-rock aquifer material) would be less likely to affect neighboring areas.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri954168","usgsCitation":"Burbey, T., 1997, Hydrogeology and potential for ground-water development, carbonate-rock aquifers, southern Nevada and southeastern California: U.S. Geological Survey Water-Resources Investigations Report 95-4168, v, 65 p., https://doi.org/10.3133/wri954168.","productDescription":"v, 65 p.","costCenters":[],"links":[{"id":55195,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1995/4168/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123682,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1995/4168/report-thumb.jpg"},{"id":395394,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48263.htm"}],"country":"United States","state":"California, Nevada","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -117.05,\n 35.5667\n ],\n [\n -114.3333,\n 35.5667\n ],\n [\n -114.3333,\n 37.7278\n ],\n [\n -117.05,\n 37.7278\n ],\n [\n -117.05,\n 35.5667\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adbe4b07f02db685a2b","contributors":{"authors":[{"text":"Burbey, T.
