The user describes a 'design storm' in terms of average rainfall intensity and storm duration. Information required to compute runoff for the design storm by using the model include (1) soil type and description, and (2) two infiltration parameters and a surface-retention storage parameter. Parameter values are tabulated in the report. Rainfall and runoff data for three ephemeral-stream basins that contain only one type of soil were used to develop the model. Two assumptions were necessary: antecedent soil moisture is some long-term average, and storm rainfall is uniform in both time and space. The infiltration and surface-retention storage parameters were determined for the soil of each basin. Observed rainstorm and runoff data were used to develop a separation curve, or incipient-runoff curve, which distinguishes between runoff and nonrunoff rainfall data. The position of this curve defines the infiltration and surface-retention storage parameters. \r\n\r\nA procedure for applying the model to basins that contain more than one type of soil was developed using data from 7 of the 10 study basins. For these multiple-soil basins, the incipient-runoff curve defines the infiltration and retention-storage parameters for the soil having the highest runoff potential. Parameters were defined by ranking the soils according to their relative permeabilities and optimizing the position of the incipient-runoff curve by using measured runoff as a control for the fit. Analyses of runoff from multiple-soil basins indicate that the effective contributing area of runoff is less than the drainage area of the basin. In this study, the effective drainage area ranged from 41.6 to 71.1 percent of the total drainage area. Information on effective drainage area is useful in evaluating drainage area as an independent variable in statistical analyses of hydrologic data, such as annual peak frequency distributions and sediment yield.A comparison was made of the sum of the simulated runoff and the sum of the measured runoff for all available records of runoff-producing storms in the 10 study basins. The sums of the simulated runoff ranged from 12.0 percent less than to 23.4 percent more than the sums of the measured runoff. A measure of the standard error of estimate was computed for each data set. These values ranged from 20 to 70 percent of the mean value of the measured runoff. \r\n\r\nRainfall-simulator infiltrometer tests were made in two small basins. The amount of water uptake measured by the test in Dugout Creek tributary basin averaged about three times greater than the amount of water uptake computed from rainfall and runoff data. Therefore, infiltrometer data were not used to determine infiltration rates for this study.","language":"ENGLISH","publisher":"U.S. Govt. Print.

These bedrock units and glacial deposits have been designated for study as part of the U.S. Geological Survey 's Regional Aquifer System Analysis program, a nationwide program to assess the regional hydrology, geology and water quality of the Nation 's most important aquifers. The purpose of the study is to define the hydrology, geochemistry, and geologic framework of the aquifer system within the Silurian and Devonian rocks and glacial deposits, with emphasis on describing the groundwater flow patterns and characterizing the water quality. The study, which began in 1988 , is expected to be completed in 1993. In 1980, the aquifers in the study area supplied more than 280 million gallons of water/day to industry, agriculture, and a population of more than 6.3 million people. With a projected future population growth to 7.1 million in 1990, and with intensified agricultural and industrial uses, water withdrawals from these bedrock and glacial aquifers are expected to be increased. The most significant groundwater problems in the study area result from the pronounced areal differences in availability and quality of the groundwater. These differences are related to the lateral discontinuity of many of the glacial deposits and to variations in secondary permeability of the bedrock aquifers associated with patterns of fracturing. Planned activities of the study include compilation of available geohydrologic and water quality data, such as groundwater levels, geohydrologic properties of aquifers, chemical analyses, land use and water use data, and ancillary data such as digital satellite images. Additional geohydrologic and water quality data may be collected from existing wells or wells that may be drilled for this study. A computerized, geographic information system will be used as a data base management tool and for spatial analysis and presentation of the data. A digital computer model will be developed to study the regional groundwater flow system and to investigate the effects of development on the aquifer system.

Three sites on two cold-water trout streams Black Earth Creek at Cross Plains, Black Earth Creek near Cross Plains, and Garfoot Creek near Cross Plains were continuously monitored for streamflow and water-quality data. One site in a warm-water stream, Brewery Creek at Cross Plains, also was monitored. Aquatic macrophyte biomass was determined for three sites on Black Earth Creek.</p>\n<p>Streamflow at Black Earth Creek at Black Earth during the 1985 and 1986 water years (WY) were 44 and 60 percent greater than the long-term mean discharge of 33.3 ft3/s (cubic feet per second) for the period 1955-86. Water year 1986 had the highest annual mean discharge, 53.4 ft3/s, since records began in 1954 at the most downstream site Black Earth Creek at Black Earth. Although there have been considerable fluctuations in streamflow, it has tended to increase since WY 1965 as a result of above-average precipitation and consequent rising ground-water levels.</p>\n<p>Trout population densities may be related to annual mean streamflow. A regression analysis of adult trout populations and the 3-year moving annual mean discharge had a correlation coefficient of 0.75 with a standard error of 83 percent.</p>\n<p>Aquatic macrophyte biomass in Black Earth Creek was substantially less in 1986 than in 1985 as a result of substrate scouring from the flood of July 25, 1985. The frequency of occurrence of species during 1985 and 1986 was similar to that of 1981, and seasonal succession of species also was similar; Potamogeton crispus dominated early in the year and senesced in July. P. crispus and P. pectinatus, both indicative of eutrophic conditions, dominated upstream and downstream, respectively; neither species is native to the area. In 1985, the greatest biomass was found upstream from Cross Plains. This large biomass caused diurnal fluctuations in dissolved-oxygen concentration of 5 to 6 mg/L (milligrams per liter) as a result of photosynthesis and respiration. Many of the dissolved-oxygen minimums, recorded at night, were less than the State 6.0-mg/L water-quality standard for trout waters. Discharge from point sources may adversely affect Black Earth Creek's water quality. Warm water discharged to Black Earth Creek from a gravel pit operation upstream from Cross Plains increased water temperatures 2 to 4 degrees Celsius and decreased the dissolved oxygen about 1 mg/L at a site 1.8 miles downstream. Runoff from a settling pond from a landfill operation in the headwaters of the Black Earth Creek basin drains through a wetland that drains to Black Earth Creek and contained as much as 60 mg/L ammonia nitrogen, 980 mg/L biochemical oxygen demand, and 1,300 mg/L chemical oxygen demand, which may be detrimental to trout.</p>\n<p>Garfoot Creek had the highest suspended-sediment and phosphorus yields per unit area of the three upstream basins during low to moderate runoff. Detention ponds in the Brewery Creek basin appear to be less effective in controlling suspended-sediment and phosphorus loads during periods of high runoff than during moderate runoff. Brewery Creek had the highest concentrations of suspended sediment and total phosphorus during low and high flows. The water quality at the Black Earth Creek gaging station at Black Earth was affected by Garfoot Creek and unnamed tributaries. As a result, yields of suspended sediment, phosphorus, and nitrogen increased between Cross Plains and Black Earth. High streamflows during WY 1985 resulted in suspendedsediment yields at Black Earth Creek at Black Earth that were 29 percent greater than the 12-year (1955-65, 85-86) mean; yields ranged from 69.5 ton/mi2 (tons per square mile) in Black Earth Creek at Cross Plains to 116 ton/mi2 in the Brewery Creek basin. Phosphorus yields ranged from 312 lb/mi2 (pounds per square mile) in Black Earth Creek at Cross Plains to 628 lb/mi2 in the Brewery Creek basin. Total nitrogen yields ranged from 3,280 lb/mi2 in the Brewery Creek basin to 6,920 lb/mi2 in the Garfoot Creek basin.</p>\n<p>An increase in oxygen demand, caused by agricultural runoff, has resulted in reduced dissolved-oxygen content of the water in both Black Earth and Garfoot Creeks. The most substantial reduction occurred at Black Earth Creek at Cross Plains on July 25, 1985, as a result of the largest storm runoff event during the study. A rainfall of 5.54 inches caused streamflow discharges to increase from 9 to 122 ft3/s and dissolved-oxygen concentrations to decline to 3.0 mg/L; the dissolved-oxygen concentration was less than 6.0 mg/L for 30 hours.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri894089","collaboration":"Prepared in cooperation with the Wisconsin Department of Natural Resources","usgsCitation":"Field, S.J., and Graczyk, D., 1990, Hydrology, aquatic macrophytes, and water quality of Black Earth Creek and its tributaries, Dane County, Wisconsin, 1985-86: U.S. Geological Survey Water-Resources Investigations Report 89-4089, vi, 38 p., https://doi.org/10.3133/wri894089.","productDescription":"vi, 38 p.","numberOfPages":"44","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":55953,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1989/4089/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":122886,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1989/4089/report-thumb.jpg"}],"country":"United States","state":"Wisconsin","county":"Dane County","otherGeospatial":"Black Earth Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.72911834716797,\n              43.18440150752066\n            ],\n            [\n              -89.791259765625,\n              43.09170711357466\n            ],\n            [\n              -89.66697692871094,\n              43.06838615478111\n            ],\n            [\n              -89.54132080078125,\n              43.04555812998933\n            ],\n            [\n              -89.53239440917969,\n              43.11401670811261\n            ],\n            [\n              -89.51934814453125,\n              43.13130731581085\n            ],\n            [\n              -89.52587127685547,\n              43.14082759275761\n            ],\n            [\n              -89.72911834716797,\n              43.18440150752066\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc71d","contributors":{"authors":[{"text":"Field, S.

The watersheds include mined and reclaimed, mined and unreclaimed, and unmined agricultural land uses and are each less than 3 square miles in area. Surface-water, ground-water, and meteorologic data for the 1981 and 1982 water years were used to describe and compare hydrologic systems of the six watersheds and to identify hydrologic effects of mining and reclamation.</p>\n<p>Discharge at the unreclaimed watersheds was continuous during the study period, whereas discharge at the other watersheds was intermittent and more variable. Peak discharges were greater at the agricultural watersheds than at the unreclaimed watersheds, primarily because of large final-cut lakes in the unreclaimed watersheds. Annual runoff was greatest at the unreclaimed watersheds, intermediate at the agricultural watersheds, and least at the reclaimed watersheds.</p>\n<p>Hydrologic effects of mining were identified by comparing the hydrologic systems at mined and unreclaimed watersheds with those at unmined agricultural watersheds. These comparisons indicate that surface coal mining without reclamation can increase base flow, annual runoff, and ground-water recharge to the bedrock; reduce peak flow rates and variation in flow; lower the water table in upland areas; change the relation between surface- and ground-water divides; and create numerous, local flow systems in the shallow ground water. Hydrologic effects of reclamation were identified by comparing the hydrologic systems at mined and reclaimed watersheds with those at mined and unreclaimed watersheds. Reclamation can decrease base flow, annual runoff, and recharge to the bedrock; increase peak flow rates, variation in flow, and the response to thunderstorms; reestablish the premining relation between surface- and ground-water divides; and create fewer local flow systems in the shallow ground water.</p>\n<p>Hydrologic effects of mining and reclamation were identified by comparing the hydrologic systems at mined and reclaimed watersheds with those at unmined agricultural watersheds.

The report summarizes information on the geology, geomorphology, soils, climate, hydrology, water use, land use, population, and coal-mining history of Clay, Owen, Sullivan, and Vigo Counties in Indiana. Site-specific information is given on the morphology, geology, soils, land use, coal-mining history, and hydrologic instrumentation of the six watersheds, which are each less than 3 square miles in area.</p>\n<p>West-central Indiana is underlain by coal-bearing Pennsylvanian rocks. Nearly all of the area has been glaciated at least once and is characterized by wide flood plains and broad, flat uplands. Most of the soils have formed in loess or in loess overlying Illinoian till. The Wabash, White, and Eel Rivers are the major drainages in west-central Indiana. Average annual precipitation is about 39.5 inches per year, and average annual runoff is about 13 inches per year. The most productive aquifers are confined or unconfined outwash aquifers located along the major rivers. Bedrock aquifers are regionally insignificant but are the sole source of ground water for areas that lack outwash, alluvium, or sand and gravel lenses in till.</p>\n<p>Indiana has more than 17 billion short tons of recoverable coal reserves; about 11 percent can be mined by surface methods. Almost half of Indiana's surface reserves are in Clay, Owen, Sullivan, and Vigo Counties. More than 50,000 acres in west-central Indiana were disturbed by surface coal mining from 1941 through 1980.</p>\n<p>Big Slough and Hooker Creek are streams that drain unmined, agricultural watersheds. Row-crop corn and soybeans are the principal crops. Soils are moderately well-drained silt loams, and the watersheds have well-developed dendritic drainage systems.</p>\n<p>The unnamed tributary to Honey Creek and the unnamed tributary to Sulphur Creek are streams that drain mined and reclaimed watersheds. Ridges of mine spoil have been graded to a gently rolling topography. Soils are well drained and consist of 6 to 12 inches of silt-loam topsoil that was stockpiled and then replaced over shale and sandstone fragments of the graded mine spoil. Grasses and legumes form the vegetative cover in each watershed.</p>\n<p>Pond Creek and the unnamed tributary to Big Branch are streams that drain mined and unreclaimed watersheds. Approximately one-half of the Pond Creek watershed is unmined, agricultural land. Soils are very well-drained shaly silty loams that have formed or' steeply sloping spoil banks. Both watersheds contain numerous impoundments of water and have enclosed areas that do not contribute surface runoff to streamflow. The ridges of mine spoil are covered with pine trees, but much of the soil surface is devoid of vegetation.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Physical environment and geohydrologic effects of surface coal mining in west-central Indiana","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/wsp2368A","usgsCitation":"Martin, J.D., Crawford, C.G., Duwelius, R.F., and Renn, D.E., 1990, Description of the physical environment and coal-mining history of west-central Indiana, with emphasis on six small watersheds: U.S. Geological Survey Water Supply Paper 2368, vii, 38 p., https://doi.org/10.3133/wsp2368A.","productDescription":"vii, 38 p.","numberOfPages":"48","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":346,"text":"Indiana Water Science Center","active":true,"usgs":true}],"links":[{"id":139164,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2368a/report-thumb.jpg"},{"id":30119,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2368a/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":394474,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25298.htm"}],"country":"United States","state":"Indiana","county":"Clay County, Owen County, Sullivan County, Vigo County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.617,\n              38.9\n            ],\n            [\n              -86.633,\n              38.9\n            ],\n            [\n              -86.633,\n              39.606\n            ],\n            [\n              -87.617,\n              39.606\n            ],\n            [\n              -87.617,\n              38.9\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aaae4b07f02db6690ea","contributors":{"authors":[{"text":"Martin, Jeffrey D. 0000-0003-1994-5285 jdmartin@usgs.gov","orcid":"https://orcid.org/0000-0003-1994-5285","contributorId":1066,"corporation":false,"usgs":true,"family":"Martin","given":"Jeffrey","email":"jdmartin@usgs.gov","middleInitial":"D.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":27231,"text":"Indiana-Kentucky Water Science Center","active":true,"usgs":true},{"id":346,"text":"Indiana Water Science Center","active":true,"usgs":true}],"preferred":true,"id":146354,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crawford, Charles G. 0000-0003-1653-7841 cgcrawfo@usgs.gov","orcid":"https://orcid.org/0000-0003-1653-7841","contributorId":1064,"corporation":false,"usgs":true,"family":"Crawford","given":"Charles","email":"cgcrawfo@usgs.gov","middleInitial":"G.","affiliations":[{"id":37947,"text":"Upper Midwest Water Science Center","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":146353,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Duwelius, Richard F.","contributorId":31378,"corporation":false,"usgs":true,"family":"Duwelius","given":"Richard","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":146356,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Renn, Danny E.","contributorId":14808,"corporation":false,"usgs":true,"family":"Renn","given":"Danny","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":146355,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The aquifer is present throughout Iowa and is confined beneath other aquifers in much of the State. Information on the aquifer available from drillers and contractors, provided estimates of aquifer transmissivity values ranging from about 500 to about 3,000 square feet per day. The largest transmissivity values are for dolomite and dolomite-cemented sandstone, indicating that permeability in much of the aquifer is due to secondary fractures. The aquifer is vertically bounded by an upper leaky confining unit with a vertical hydraulic conductivity of 10<sup>-10</sup> feet per second.</p>\n<p>The aquifer was simulated using a two-layer finite-difference ground-water flow model. The upper layer simulated a source bed in aquifers composed of Silurian and Devonian rocks overlying the St. Peter-Jordan aquifer. The lower layer simulated flow in the St. Peter-Jordan aquifer. Lateral boundaries assigned in the model include constant heads in northeastern Iowa, where the aquifer is in contact with the Mississippi River or is unconfined, and no-flow boundaries in western and northwestern Iowa, where the rocks are insufficiently permeable to form an aquifer. The aquifer boundaries to the north, east, and south of Iowa were determined by geohydrologic conditions and the relation of the St. Peter-Jordan aquifer with the lateral extent of adjacent aquifers.</p>\n<p>An assumption that the largest part of recharge to the aquifer is from outcrop areas in northeastern Iowa and from Minnesota is not supported by the results of this study. Vertical leakage from overlying rocks accounted for most of the recharge to the aquifer in northwestern Iowa. Discharge is mostly through lateral boundaries and to rivers.</p>\n<p>Pumping has caused changes in the flow system that include regional declines in the potentiometric surface of the aquifer. Simulation indicates that pumping through 1980 increased net vertical leakage into the aquifer to about double the predevelopment rate. Discharge across lateral boundaries has been substantially reduced or reversed by pumping. Aquifer storage provided about one-third of the water required to supply pumping in the 1970's. Simulation of future conditions, assuming no increase in pumping rates, indicates that the rate of decline in water levels will decrease by the year 2020. As equilibrium with pumping is approached in 2020, 75 percent of the pumpage will be balanced by vertical leakage, eight percent by water released from aquifer storage, and 17 percent by increases in boundary recharge or decreases in boundary discharge. Future pumping at an increasing rate of about 10 percent per decade of the average pumping rate in 1975 will require about one and one-half times the vertical leakage of the 1971-1980 period and about fivetimes the net inflow from lateral boundaries; however, the rate of water released from aquifer storage will be about half the 1970's rate. Under these conditions, the head in the aquifer will continue to decline at an almost constant rate until 2020.</p>","language":"English","publisher":"U.S. Geological

Geophysical logs can provide information on the construction of wells and on the character of the rocks and fluids penetrated by those wells, as well as on changes in the character of these factors over time. The response of well logs is caused by petrophysical factors, by the quality, temperature, and pressure of interstitial fluids, and by ground-water flow. Qualitative\r\nand quantitative analysis of analog records and computer analysis of digitized logs are used to derive geohydrologic information. This information can then be extrapolated vertically within a well and laterally to other wells using logs.\r\nThe physical principles by which the mechanical and electronic components of a logging system measure properties of rocks, fluids, and wells, as well as the principles of measurement, must be understood if geophysical logs are to be interpreted correctly. Plating a logging operation involves selecting the equipment and the logs most likely to provide the needed information. Information on well construction and geohydrology is needed to guide this selection. Quality control of logs is an important responsibility of both the equipment operator and the log analyst and requires both calibration and well-site standardization of equipment.  Logging techniques that are widely used in ground-water hydrology or that have significant potential for application to this field include spontaneous potential, resistance, resistivity, gamma, gamma spectrometry, gamma-gamma, neutron, acoustic velocity, acoustic televiewer, caliper, and fluid temperature, conductivity, and flow. The following topics are discussed for each of these techniques: principles and instrumentation, calibration and standardization, volume of investigation, extraneous effects, and interpretation and applications.","language":"ENGLISH","publisher":"U.S. G.P.O. ;For sale by the Books and Open-File Reports Section, U.S. Geological Survey,","doi":"10.3133/twri02E2","issn":"0565-596X","usgsCitation":"Keys, W., 1990, Borehole geophysics applied to ground-water investigations: U.S. Geological Survey Techniques of Water-Resources Investigations 02-E2, xvi, 150 p. :ill. ; 28 cm., https://doi.org/10.3133/twri02E2.","productDescription":"xvi, 150 p. :ill. ; 28 cm.","costCenters":[],"links":[{"id":139095,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":286,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/twri/twri2-e2/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dce4b07f02db5e1c53","contributors":{"authors":[{"text":"Keys, W.S.","contributorId":75126,"corporation":false,"usgs":true,"family":"Keys","given":"W.S.","email":"","affiliations":[],"preferred":false,"id":149632,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Another graph defines the relation between drainage area and median depth of flow over the low point of riffles.

About 20 feet of clay underlying the Delta land surface commonly is underlain by about 80 to 180 feet of sand and gravel that forms the Mississippi River alluvial aquifer. This study of the alluvial aquifer was prompted by recent declines of water levels. The study was designed to better define the hydrology of the aquifer and to quantify availability of water from the aquifer. \r\n\r\nThe Mississippi River is in good hydraulic connection with the alluvial aquifer. Generally, smaller streams are less likely to recharge the aquifer than larger streams. Direct vertical recharge to the alluvial aquifer from the 52 inches per year of precipitation is small, especially in the central part of the Delta. \r\n\r\nA two-dimensional finite-difference computer model of the alluvial aquifer was constructed, calibrated, and verified using water levels observed for five dates from April 1981 to September 1983. The values of some of the calibration-derived parameters are hydraulic conductivity, 400 feet per day; specific yield, 0.30; and infiltration of precipitation to the aquifer, 0.5 inch per year. \r\n\r\nThe model showed that the aquifer had a net loss in storage of about 360 million gallons per day from April 1981 to April 1983. During this period, pumpage was about 1,100 million gallons per day (1,270,000 acre-feet per year), and the net inflows from the sources of recharge were as follows, in million gallons per day: Mississippi River, 390; recharge along the east edge of the Delta, 170; streams within the Delta, 57; areal recharge from infiltration, 180; and oxbow lakes, 24. \r\n\r\nThe effects of several levels of pumpage by wells--0, 670, 1,100, 1,900, and 4,000 million gallons per day--were projected 20 years into the future. In 2003, the 1,100-milliongallon-per-day pumping rate, about average for the early 1980's, would take 46 percent of the water withdrawn from aquifer storage, water levels would be lowered more than 20 feet in a large area in the central part of the Delta, and groundwater levels would continue to decline in future years.","language":"ENGLISH","publisher":"U.S. G.P.O. ;\r\nFor sale by the Books and Open-File Reports Section, U.S. Geological Survey,","doi":"10.3133/wsp2292","usgsCitation":"Sumner, D.M., and Wasson, B.E., 1990, Geohydrology and simulated effects of large ground-water withdrawals on the Mississippi River alluvial aquifer in northwestern Mississippi: U.S. Geological Survey Water Supply Paper 2292, vi, 60 p. :ill., maps ;28 cm., https://doi.org/10.3133/wsp2292.","productDescription":"vi, 60 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":138668,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2292/report-thumb.jpg"},{"id":29220,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2292/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a8c76","contributors":{"authors":[{"text":"Sumner, D.

Hydrologic investigations in Iowa are made through three basic types of projects: (1) hydrologic data-collection programs; (2) local or areal hydrologic studies; and (3) statewide or regional investigations. These projects are funded through cooperative joint-funding agreements with Federal, State, and local agencies and direct Federal funds. The data and the results of the interpretive studies are published or released by either the U.S. Geological Survey or by cooperating agencies. This report describes: (1) the hydrologic data-collection programs; (2) the local or areal hydrologic investigations; and (3) statewide or regional studies conducted by the U.S Geological Survey in

To model the effects that the Garrison Diverson Unit could have on water quantity, monthly gaged and estimated streamflow data and estimated unregulated streamflow data were compiled to develop a complete monthly streamflow record for January 1931 through December 1984 (data-development period) for 29 sites in the Red River of the North basin.</p><p>Gaged streamflow records were available for January 1931 through December 1984 for only 4 sites; no records or records of various length were available for the remaining 25 sites.

During recent years, the District completed several investigations as well as initiated others. An intense effort has been made to publish interpretive reports and data on a near-current basis. As a result of this effort, a significant number of water resources reports were completed and/or published during the 1989 fiscal year. This report contains a complete list of USGS reports addressing West Virginia hydrology as of December 1989. The mission of the Water Resources Division is to provide the hydrologic information and understanding needed for the optimum utilization and management of the Nation 's water resources for the overall benefit of the people in the United States. This is accomplished, in large part , through cooperation with other Federal and non-Federal agencies, by: (1) Collecting, on a systematic basis, data needed for the continuing determination and evaluation of the quantity, quality, and use of the Nation 's water resources; (2) Conducting analytical and interpretive water resource appraisals describing the occurrence, availability, and the physical, chemical, and biological characteristics of surface and groundwater; (3) conducting supportive basic and problem-oriented research in hydraulics, hydrology, and related fields of science to improve the scientific basis for investigations and measurement techniques and to understand hydrologic systems sufficiently well to quantitatively predict their response to stress, either natural or manmade; (4) disseminating the water data and the results of these investigations and research through reports, maps, computerized information services, and other forms of public releases; (5) Coordinating the activities of Federal agencies in the acquisition of water data for streams, lakes, reservoirs, estuaries, and groundwaters; and (6) Providing scientific and technical assistance in hydrologic fields to other Federal, State and local agencies, to licensees of the Federal Power Commission, and to international agencies on behalf of the Department of State.

Descriptions of existing conditions may be achieved by various kinds of chemical and hydrologic analyses, whereas information about the effects of such conditions on living organisms depends on biological monitoring. Toxicity testing is one type of biological monitoring that can be used to identify possible effects of toxic contaminants. \r\n\r\nBased on experimentation designed to monitor responses of organisms to environmental stresses, toxicity testing may have diverse purposes in water-quality assessments. These purposes may include identification of areas that warrant further study because of poor water quality or unusual ecological features, verification of other types of monitoring, or assessment of contaminant effects on aquatic communities. Toxicity-test results are most effective when used as a complement to chemical analyses, \r\n\r\nhydrologic measurements, and other biological monitoring. However, all toxicity-testing procedures have certain limitations that must be considered in developing the methodology and applications of toxicity testing in any large-scale water-quality-assessment program. A wide variety of toxicity-test methods have been developed to fulfill the needs of diverse applications. The methods differ primarily in the selections made relative to four characteristics: (1) test species, (2) endpoint (acute or chronic), (3) test-enclosure type, and (4) test substance (toxicant) that functions as the environmental stress. Toxicity-test approaches vary in their capacity to meet the needs of large-scale assessments of existing water quality. Ambient testing, whereby the test organism is exposed to naturally occurring substances that contain toxicant mixtures in an organic or inorganic matrix, is more likely to meet these needs than are procedures that call for exposure of the test organisms to known concentrations of a single toxicant. However, meaningful interpretation of ambient test results depends on the existence of accompanying chemical analysis of the ambient media. The ambient test substance may be water or sediments. \r\n\r\nSediment tests have had limited application, but they are useful because most toxicants tend to accumulate in sediments and many test species either inhabit the sediments or are in frequent contact with them. Biochemical testing methods, which have been developing rapidly in recent years, are likely to be among the most useful procedures for large-scale water-quality assessments. They are relatively rapid and simple, and more. importantly, they focus on biochemical changes that are the initial responses of virtually all organisms to environmental stimuli. \r\n\r\nMost species are sensitive to relatively few toxicants, and their sensitivities vary as conditions change. Therefore, each test method has particular uses and limitations, and no single test has universal applicability. One of the most informative approaches to toxicity testing is to combine biochemical tests with other test methods in a 'battery of tests' that is diversified enough to characterize different types of toxicants and different trophic levels. However, such an approach can be costly, and if not carefully designed, it may not yield enough additional information to warrant the additional cost. \r\n\r\nThe application of toxicity tests to large-scale water-quality assessments is hampered by a number of difficulties. Toxicity tests often are not sensitive enough to enable detection of most contaminant problems in the natural environment. Furthermore, because sensitivities among different species and test conditions can be highly variable, conclusions about the toxicant problems of an ecosystem are strongly dependent on the test procedure used. In addition, the experimental systems used in toxicity tests cannot replicate the complexity or variability of natural conditions, and positive test results cannot identify the source or nature of","language":"ENGLISH","publisher":"U.S. G.P.O. ;\r\nBooks and Open-File Reports Section [distributor],","doi":"10.3133/cir1049","usgsCitation":"Elder, J.F., 1990, Applicability of ambient toxicity testing to national or regional water-quality assessment: U.S. Geological Survey Circular 1049, iv, 49 p. :ill. ;28 cm., https://doi.org/10.3133/cir1049.","productDescription":"iv, 49 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":120769,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1990/1049/report-thumb.jpg"},{"id":31061,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1990/1049/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67ac0b","contributors":{"authors":[{"text":"Elder, John F.","contributorId":23919,"corporation":false,"usgs":true,"family":"Elder","given":"John","email":"","middleInitial":"F.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":147937,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
