Underseepage is thought to occur primarily on the northeast side of the dam in the lower bedrock of the St. Louis Limestone, which consists of discontinuous basal evaporite beds and an overlying cavity zone. Because of concerns about the integrity of the dam, the U.S. Army Corps of Engineers initiated a remedial grouting program in September 1991. To assess the effectiveness of the remedial grouting program and to evaluate methods for future assessments, a study was conducted by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers.</p>\n<p>Potentiometric surface maps of the overburden and bedrock indicate that the direction of ground-water flow on the northeast side of the dam has changed little from pre-grout to post-grout periods. A comparison of water levels, between a pre-grout date and a post-grout date, shows that water levels decreased but that the decrease may be more attributable to changes in dam operations than to remedial grouting. Waterlevel data for the same two dates indicate that a more gradual potentiometric surface exists on the northeast side of the dam than on the southwest side of the dam, which suggests that the hydraulic connection between Lake Red Rock and downgradient bedrock wells still is greater on the northeast side of the dam than on the southwest side. Hydrographs for some wells on the northeast side of the dam indicated a departure from pre-grout trends at approximately the same time grouting was initiated. To varying degrees, hydrographs for the same wells then appear to return to a trend similar to pre-grout years, possibly as a result of new flow paths developing over time after remedial grouting. Spearman correlation coefficients computed for water levels in wells, pool, and tailwater indicate that some areas on the northeast side of the dam appear to be less under the influence of changing pool elevations after grouting than before grouting. This suggests that the hydraulic connection between the Red Rock pool and some downgradient areas has decreased.</p>\n<p>Analysis of water samples collected from selected wells on the northeast side of the dam shows significant increases in sulfate concentrations beginning about the same time remedial grouting was done upgradient from the wells, possibly indicating that flow paths were cut off to these wells, thereby reducing the amount of mixing with fresh reservoir water. Observable changes in chloride concentrations or trends as a result of remedial grouting were not apparent. Analysis results for hydrogen and oxygen stable isotope samples collected since 1995 indicate large seasonal fluctuations of isotope ratios in the tailwater (assumed representative of the reservoir). Similar but more subdued fluctuations were observed at some wells, but other wells appeared to have little seasonal change. Stable sulfur isotope results indicate the presence of distinct water types between Lake Red Rock and in ground water from downgradient bedrock wells. Sulfur isotope values from samples from a bedrock well located upgradient from the grout curtain indicate a mixture of pool and ground water, whereas samples from downgradient overburden wells have values similar to the pool. Samples from the bedrock wells downgradient from the grout curtain have sulfur isotope values similar to a value obtained from analysis of a gypsum and anhydrite core sample.</p>\n<p>Hydrographs, statistical analysis of waterlevel data, and water-chemistry data suggest that underseepage on the northeast side of the dam has been reduced but not completely eliminated. Some areas appear to have been affected to a greater degree and for a longer period of time than other areas. Future monitoring of water levels, water chemistry, and stable isotopes can aid in the evaluation of the long-term effectiveness of remedial grouting.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri004231","collaboration":"Prepared in cooperation with the U.S. Army Corps of Engineers Rock Island District, Rock Island, Illinois","usgsCitation":"Linhart, S., and Schaap, B.D., 2001, Effects of remedial grouting on the ground-water flow system at Red Rock Dam near Pella, Iowa: U.S. Geological Survey Water-Resources Investigations Report 2000-4231, v, 35 p., https://doi.org/10.3133/wri004231.","productDescription":"v, 35 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":351,"text":"Iowa Water Science Center","active":true,"usgs":true}],"links":[{"id":316675,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri004231.JPG"},{"id":2786,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://ia.water.usgs.gov/pubs/reports/WRIR_00-4231.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Iowa","otherGeospatial":"Red Rock Dam","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.96545028686523,\n              41.38212180399892\n            ],\n            [\n              -92.96828269958496,\n              41.3802863707537\n            ],\n            [\n              -92.97055721282959,\n              41.37845088570654\n            ],\n            [\n              -92.97330379486084,\n              41.376518740220305\n            ],\n            [\n              -92.97484874725342,\n              41.37535942537781\n            ],\n            [\n              -92.97738075256348,\n              41.373427188056084\n            ],\n            [\n              -92.98017024993895,\n              41.3712372497054\n            ],\n            [\n              -92.98265933990479,\n              41.36949812849777\n            ],\n            [\n              -92.98527717590332,\n              41.36750130237204\n            ],\n            [\n              -92.98707962036131,\n              41.36595533037855\n            ],\n            [\n              -92.98879623413086,\n              41.36434490382504\n            ],\n            [\n              -92.98892498016357,\n              41.36192918926284\n            ],\n            [\n              -92.98669338226318,\n              41.36128498356731\n            ],\n            [\n              -92.98373222351074,\n              41.36134940442383\n            ],\n            [\n              -92.9814577102661,\n              41.36286327619405\n            ],\n            [\n              -92.98012733459473,\n              41.365053496418994\n            ],\n            [\n              -92.97836780548096,\n              41.366502866327224\n            ],\n            [\n              -92.97660827636719,\n              41.36827427459402\n            ],\n            [\n              -92.97574996948242,\n              41.368982824396916\n            ],\n            [\n              -92.9721450805664,\n              41.37027107699629\n            ],\n            [\n              -92.96729564666748,\n              41.37358821002511\n            ],\n            [\n              -92.96536445617674,\n              41.37481196396403\n            ],\n            [\n              -92.96296119689941,\n              41.37696957930098\n            ],\n            [\n              -92.9622745513916,\n              41.3787729043739\n            ],\n            [\n              -92.96188831329346,\n              41.380640581203295\n            ],\n            [\n              -92.96347618103027,\n              41.38196080315539\n            ],\n            [\n              -92.96545028686523,\n              41.38212180399892\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db6116d2","contributors":{"authors":[{"text":"Linhart, S.

This study includes stream-habitat assessments, aquatic invertebrate and fish-community surveys in selected stream reaches, and analyses of mercury and lead concentrations in largemouth bass (Micropterous salmoides) muscle tissue from three impoundments. \r\n\r\nAssessment surveys indicate lower habitat value scores in some streams draining the more developed areas on Fort Gordon. A small tributary to Butler Creek--which drains parking lots associated with military motor pools and other impervious surfaces--is characterized by moderate levels of bank erosion and excess sediment in the stream channel compared to reference sites. Four other stream reaches are more similar to reference streams in respect to habitat conditions. Invertebrate communities in streams draining these urbanized watersheds are inhabited by 13 to 16 taxa per reach; whereas, 23 and 33 taxa were collected from the two reference stream reaches. Measures of invertebrate abundance, taxa richness, Ephemeroptera, Plecoptera, and Tricoptera Index are lower in streams draining urbanized watersheds. Measures of community similarity also indicate differences between streams draining urbanized areas and reference streams. Streams draining developed areas on Fort Gordon are inhabited by 3 to 10 fish species and included more species regarded as tolerant of degraded water-quality conditions; whereas, the two reference stream reaches support 4 and 10 species, respectively, including one species considered intolerant of degraded water-quality conditions. \r\n\r\nMercury was detected in all largemouth bass collected from three impoundments on Fort Gordon. Wet-weight mercury concentrations in fish tissue analyzed from all sites range from 0.08 micrograms per gram to 1.33 micrograms per gram. Median mercury concentrations in fish tissue are 0.83 micrograms per gram at Soil Erosion Lake, 0.72 micrograms per gram at Lower Leitner Lake, and 0.22 micrograms per gram at Gordon Lake. Median mercury concentrations in fish tissue analyzed from Soil Erosion Lake and Lower Leitner Lake are more than two times higher than U.S. Environmental Protection Agency recommendation of 0.3 micrograms per gram for fish consumption. Lead concentrations are below the minimum reporting limit for all specimens analyzed from reservoirs sampled at Fort Gordon.","language":"ENGLISH","doi":"10.3133/ofr2001203","usgsCitation":"Gregory, M.B., Stamey, T.C., and Wellborn, J.B., 2001, Ecological characterization of streams, and fish-tissue analysis for mercury and lead at selected locations, Fort Gordon, Georgia, June 1999 to May 2000: U.S. Geological Survey Open-File Report 2001-203, iv, 24 p., https://doi.org/10.3133/ofr2001203.","productDescription":"iv, 24 p.","temporalStart":"1999-06-01","temporalEnd":"2000-05-31","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":161323,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":8947,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr01-203/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Georgia","city":"Fort Gordon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -83.71307373046874,\n              35.67068501330236\n            ],\n            [\n              -83.71307373046874,\n              35.67068501330236\n            ],\n            [\n              -83.7103271484375,\n              35.67068501330236\n            ],\n            [\n              -83.7103271484375,\n              35.67068501330236\n            ],\n            [\n              -83.71307373046874,\n              35.67068501330236\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -82.64465332031249,\n              33.15709799197017\n            ],\n            [\n              -82.64465332031249,\n              33.684353657331016\n            ],\n            [\n              -81.837158203125,\n              33.684353657331016\n            ],\n            [\n              -81.837158203125,\n              33.15709799197017\n            ],\n            [\n              -82.64465332031249,\n              33.15709799197017\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ee4b07f02db627c8b","contributors":{"authors":[{"text":"Gregory, M.

Accurate hydraulic heads are particularly important in Frenchman Flat where the hydraulic gradients are relatively flat (less than 1 foot per mile) in the alluvial aquifer. Temporal water-level trends with magnitudes near or exceeding the regional hydraulic gradient may have a substantial effect on ground-water flow directions.\r\n\r\nWater-level measurements can be adjusted for the effects of barometric pressure, formation water density (from water-temperature measurements), borehole deviation, and land-surface altitude in selected wells in the Frenchman Flat area. Water levels in one well were adjusted for the effect of density; this adjustment was significantly greater (about 17 feet) than the adjustment of water levels for barometric pressure, borehole deviation, or land-surface altitude (less than about 4 feet).\r\n\r\nWater-level measurements from five wells exhibited trends that were statistically and hydrologically significant. Statistically significant water-level trends were observed for three wells completed in the alluvial aquifer (WW-5a, UE-5n, and PW-3), for one well completed in the carbonate aquifer (SM-23), and for one well completed in the quartzite confining unit (Army-6a).\r\n\r\nPotential causes of water-level fluctuations in wells in the Frenchman Flat area include changes in atmospheric conditions (precipitation and barometric pressure), Earth tides, seismic activity, past underground nuclear testing, and nearby pumping. Periodic water-level measurements in some wells completed in the carbonate aquifer indicate cyclic-type water-level fluctuations that generally correlate with longer term changes (more than 5 years) in precipitation. Ground-water pumping fromthe alluvial aquifer at well WW-5c and pumping and discharge from well RNM-2s appear to cause water-level fluctuations in nearby observation wells. The remaining known sources of water-level fluctuations do not appear to substantially affect water-level changes (seismic activity and underground nuclear testing) or do not affect changes over a period of more than 1 year (barometric pressure and Earth tides) in wells in the Frenchman Flat area.","language":"ENGLISH","doi":"10.3133/wri004272","usgsCitation":"Bright, D., Watkins, S., and Lisle, B., 2001, Analysis of water levels in the Frenchman Flat area, Nevada Test Site: U.S. Geological Survey Water-Resources Investigations Report 2000-4272, 43 p. , https://doi.org/10.3133/wri004272.","productDescription":"43 p.

The waste piles are subjected to about 50 inches of rainfall a year, resulting in the dissolution of the salts and metal. To assess the potential threat to underlying ground-water resources at the site, its hydrogeology was characterized by measuring water levels and field parameters of water quality in 23 wells and at 2 surface-water sites. Seventeen of these monitor wells were constructed at various depths for this study to allow for the separate characterization of the shallow and deep ground-water  systems, the calculation of vertical gradients, and the collection of water samples at different depths within the flow system. Lithologic descriptions from drill-hole cuttings and geophysical logs indicate the presence of interbedded sands, gravels, silts, and clays to depths of 65 feet. The regionally important Sparta aquifer underlies the site. Water levels in shallow wells indicate radial flow away from the salt-cake pile located near the center of the site. Flow in the deep system is to the west and southwest toward Bodcau Creek. Water-level data from eight piezometer nests indicate a downward hydraulic gradient from the shallow to deep systems across the site. Values of specific conductance (an indicator of dissolved salts) ranged from 215 to 196,200 microsiemens per centimeter and indicate that saline waters are being transported horizontally and vertically downward away from the site","language":"ENGLISH","doi":"10.3133/ofr01201","usgsCitation":"Czarnecki, J.B., Stanton, G.P., and Freiwald, D.A., 2001, Hydrogeology and physical characteristics of water samples at the Red River aluminum site, Stamps, Arkansas, April 2001: U.S. Geological Survey Open-File Report 2001-201, 30 p., https://doi.org/10.3133/ofr01201.","productDescription":"30 p.","costCenters":[],"links":[{"id":161322,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0201/report-thumb.jpg"},{"id":59730,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0201/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4be4b07f02db625501","contributors":{"authors":[{"text":"Czarnecki, John B. jczarnec@usgs.gov","contributorId":2555,"corporation":false,"usgs":true,"family":"Czarnecki","given":"John","email":"jczarnec@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":true,"id":205630,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stanton, Gregory P. 0000-0001-8622-0933 gstanton@usgs.gov","orcid":"https://orcid.org/0000-0001-8622-0933","contributorId":1583,"corporation":false,"usgs":true,"family":"Stanton","given":"Gregory","email":"gstanton@usgs.gov","middleInitial":"P.","affiliations":[],"preferred":true,"id":205629,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Freiwald, David A. freiwald@usgs.gov","contributorId":226,"corporation":false,"usgs":true,"family":"Freiwald","given":"David","email":"freiwald@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":205628,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

For example, a compact pulse of prey migrating through a field of quasi-stationary predators may not be well described by standard predator-prey models, because the predators and prey are unlikely to be well mixed; that is, the prey may be exposed to only a fraction of the predator population at a time. This underscores the importance of properly accounting for the ecological neighborhood, or effective feeding range, of predators in models. We illustrate this situation with a series of models of salmon smolts migrating through a reservoir arrayed with predators. The reservoir is divided into a number of longitudinal compartments or spatial cells, the length of each cell representing the upstream-downstream range over which predators can forage. In this series of models a 100-km-long reservoir is divided, successively into 2, 5, 10, 25, 50, 100, 200, and 400 cells, with respective cell lengths of 50, 20, 10, 4, 2, 1, 0.5, and 0.25 km. We used a detailed individual-based simulation model at first, but to ensure robustness of results we supplemented this with a simple analytic model. Both models showed sharp differences in the predicted mortality to a compact pulse of smolt prey moving through the reservoir, depending on the number of spatial cells in the model. In particular, models with fewer than about 10 cells vastly overpredicted the amount of mortality due to predators with activity ranges of not more than a few kilometers. These results corroborate recent theoretical and simulation studies on the importance of spatial scale and behavior in modeling predator-prey dynamics.</span></p>","language":"English","publisher":"Wiley","doi":"10.1034/j.1600-0706.2001.940212.x","usgsCitation":"DeAngelis, D., and Petersen, J.H., 2001, Importance of the predator's ecological neighborhood in modeling predation on migrating prey: Oikos, v. 94, no. 2, p. 315-325, https://doi.org/10.1034/j.1600-0706.2001.940212.x.","productDescription":"11 p.","startPage":"315","endPage":"325","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":314158,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"2","noUsgsAuthors":false,"publicationDate":"2003-04-10","publicationStatus":"PW","scienceBaseUri":"5694e047e4b039675d005e29","contributors":{"authors":[{"text":"DeAngelis, Donald L. 0000-0002-1570-4057 don_deangelis@usgs.gov","orcid":"https://orcid.org/0000-0002-1570-4057","contributorId":147289,"corporation":false,"usgs":true,"family":"DeAngelis","given":"Donald L.","email":"don_deangelis@usgs.gov","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":false,"id":588274,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Petersen, James H. petersen@usgs.gov","contributorId":23231,"corporation":false,"usgs":true,"family":"Petersen","given":"James","email":"petersen@usgs.gov","middleInitial":"H.","affiliations":[],"preferred":false,"id":588275,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The rocks represent all of the stratigraphic systems from Cambrian to Cretaceous and all but one of the tectono-stratigraphic subterranes of the Brooks Range, from the autochthonous subterrane in the north to the allochthonous subterranes farther south. Among the distinctive geologic features displayed in the Arctic quadrangle are voluminous volcanic rocks of probable Devonian age, a wide array of Carboniferous carbonate facies in the Lisburne Group (which here extends up into the Middle Pennsylvanian), the southward transition of Upper Devonian (Famennian) clastic facies from fluvial conglomerate to marine sandstone, a full display of Upper Devonian (Frasnian) reef-related strata, and fossiliferous Ordovician rocks in both carbonate and chert terranes. Most of the quadrangle is in the Arctic National Wildlife Refuge (ANWR) and Arctic Wildlife Refuge Wilderness. The quadrangle also includes Arctic Village, the only village in the region and a potential destination or transfer point for visitors to the wildlife refuge.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/i2673","usgsCitation":"Brosge, W., Reiser, H.N., Dutro, J., Detterman, R.L., and Tailleur, I., 2001, Geologic map of the Arctic Quadrangle, Alaska (Online Version 1.0 ): U.S. Geological Survey IMAP 2673, Sheet 1, 45 by 34 inches (in color); sheet 2, 29 by 29 inches; Accompanied by 38 page text, https://doi.org/10.3133/i2673.","productDescription":"Sheet 1, 45 by 34 inches (in color); sheet 2, 29 by 29 inches; Accompanied by 38 page text","costCenters":[{"id":386,"text":"Mineral Resources - Alaska","active":false,"usgs":true}],"links":[{"id":187722,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9382,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/imap/i2673/","linkFileType":{"id":5,"text":"html"}},{"id":110196,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_42116.htm","linkFileType":{"id":5,"text":"html"},"description":"42116"}],"scale":"200000","country":"United States","state":"Alaska","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -147,68 ], [ -147,69 ], [ -144,69 ], [ -144,68 ], [ -147,68 ] ] ] } } ] }","edition":"Online Version 1.0 ","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a858a","contributors":{"authors":[{"text":"Brosge, W.

Diazinon was specifically studied in the Lafayette Creek watershed, a residential area in northeastern Tallahassee, Fla. Diazinon and other pesticides applied directly to the soil or grass can be washed off into nearby storm drains, ditches, streams, and lakes. Heavy rainstorms can wash substantial amounts of chemicals into streams and lakes, including diazinon that was applied several weeks earlier. Sampling streams during rainstorms for water quality can sometimes provide clues about how pesticides and other contaminants are transported to surface water. Diazinon was detected in 92% of all samples collected from Lafayette Creek and it was detected throughout the year during the sampling period. However, concentrations were low (0.002 to 0.28 micrograms per liter) and do not pose a risk to human health. About 20% of the samples exceeded the aquatic-life criterion--a guideline that establishes the maximum acceptable level of concentrations of pesticides for protecting aquatic life.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey,","doi":"10.3133/fs14300","usgsCitation":"Berndt, M., and Hatzell, H.H., 2001, Does diazinon pose a threat to a neighborhood stream in Tallahassee, Florida?: U.S. Geological Survey Fact Sheet 143-00, 1 folded sheet ([4] p.) : col. ill., col. maps ; 28 cm. col. ill., col. maps, https://doi.org/10.3133/fs14300.","productDescription":"1 folded sheet ([4] p.) : col. ill., col. maps ; 28 cm. col. ill., col. maps","costCenters":[],"links":[{"id":665,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://fl.water.usgs.gov/Abstracts/fs143_00_berndt.html","linkFileType":{"id":5,"text":"html"}},{"id":123913,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/fs/2000/0143/report-thumb.jpg"},{"id":31941,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/2000/0143/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db63614c","contributors":{"authors":[{"text":"Berndt, Marian P.","contributorId":45296,"corporation":false,"usgs":true,"family":"Berndt","given":"Marian P.","affiliations":[],"preferred":false,"id":150626,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hatzell, Hilda H.","contributorId":83106,"corporation":false,"usgs":true,"family":"Hatzell","given":"Hilda","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":150627,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The Liu model was validated using data published in the literature and was compared with two leading models in the literature: the Rutter and the Gash models. The Liu model was tested against the Rutter model on a single-storm basis with interception measurements observed from an old-growth Douglas fir (</span><i>Pseudotsuga menziesii</i><span>) forest in Oregon, USA. Simulated results by the Liu model were close to the measurements and comparable to those predicted by the Rutter model. The Liu model was further tested against the Gash model on a multistorm basis. The Gash and Liu models successfully predicted long-term interception losses from a broad range of 20 forests around the world. Results also indicated that both the Gash and the Liu models could be used to predict rainfall interception using daily rainfall data, although it was assumed in both models that there is only one storm per rain day. The sensitivity of the Liu model to stand storage capacity, canopy gap fraction and evaporation rate from wet canopy surface during rainfall was investigated. Results indicate that the Liu model has the simplest form, least data requirements and comparable accuracy for predicting rainfall interception as compared with the Rutter and the Gash models.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/hyp.264","usgsCitation":"Liu, S., 2001, Evaluation of the Liu model for predicting rainfall interception in forests world-wide: Hydrological Processes, v. 15, no. 2, p. 2341-1360, https://doi.org/10.1002/hyp.264.","productDescription":"20 p.","startPage":"2341","endPage":"1360","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":307626,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"2","noUsgsAuthors":false,"publicationDate":"2001-08-23","publicationStatus":"PW","scienceBaseUri":"55e034b8e4b0f42e3d040e0d","contributors":{"authors":[{"text":"Liu, Shu-Guang sliu@usgs.gov","contributorId":984,"corporation":false,"usgs":true,"family":"Liu","given":"Shu-Guang","email":"sliu@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":570390,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
