To compensate for this loss, water-quality and streamflow data were statistically analyzed and solute loads were simulated using computer techniques.</p><p>Functional relationships existing between specific conductance and solute concentration for monthly samples were used to develop linear regression models. The models were then used to simulate daily solute concentrations using daily specific conductance as the independent variable. Once simulated, the solute concentrations, in milligrams per liter, were transformed into daily solute loads, in tons, using mean daily streamflow records.</p><p>Computer output was formatted into tables listing simulated mean monthly solute concentrations, in milligrams per liter, and the monthly and annual solute loads, in tons, for water years

This report updates a previous report with 2 years of additional data collection and presents statistics and regression equations for water-quality variables. The most apparent feature of the study is the variability of water quality. Time-trend differences are most noticeable, with areal differences being present but more subtle. In comparing stations at the mouths of the five major drainages entering the Yellowstone River from the study area, water from the Powder River ranks near the middle of the group in dissolved-solids concentration (mean of 1,390 mg/L), but far exceeds the other drainages in suspended-sediment concentration, often exceeding 10,000 mg/L. The Tongue River generally has the best overall quality with respect to dissolved constituents; extremes are moderated by mixing in the Tongue River Reservoir. Suspended sediment ranged from 5 to 4,360 mg/L. Rosebud Creek shows about a 50-percent average increase in dissolved-solids concentration from the most upstream station to the mouth. Armells and Sarpy Creeks, smallest of the five drainages, have a pool-riffle configuration that influences both dissolved and suspended constituents. Pools permit greater evaporation, thus increasing dissolved-constituent concentrations. They also act as sediment traps.

An integral part of this study will be a simulation of the ground-water flow regime using the Geological Survey's three-dimensional finite-difference model. The first step in the modeling effort is the design and development of a systematic set of processes to facilitate the collection, evaluation, manipulation, and use of large quantities of information. A computerized data-base system to accomplish these goals has been completed for the northern Midwest RASA.</p>\n<p>The input to the data-base system consists of either point values or contour maps of the hydrogeologic data required by the model. Digital samples of contoured surfaces are obtained by machine digitization. Uniformly spaced model-node values are then computed from the discrete data by two-dimensional interpolation. The interpolator uses the regional (long wavelength) characteristics of the data to compute a surface with minimum total curvature. Local (short wavelength) data are merged with the regional surface to produce the model-node values at the desired spacing. Nonuniformly spaced nodal values may be obtained by fitting two-dimensional polynomials (bicubic splines) to surfaces formed by uniformly spaced points and solving for the surface values at the node locations. The uniformly or nonuniformly spaced node values constitute the output of the data-base system and in turn are the input arrays of data values for the ground-water flow model.</p>\n<p>Management of the data base is facilitated by forming a data file for each model input parameter and for other hydrogeologic data used in the study. The data files are subdivided into elements consisting of individual model-layer arrays. In this form the data base can be readily accessed and edited. In addition to the interpolation programs, software components of the system include programs: (1) to transform geographic coordinates on a Lambert conformal conic projection to cartesian coordinates and vice versa, (2) to machine contour gridded data, (3) to expedite manipulation and editing of data, and (4) to perform various interarray computations.</p>\n<p>The data-base system has the following attributes: (1) manual handling of data is minimized and machine handling of data is maximized, (2) given unequally spaced point data over the extent of a study area, model input arrays for any reasonable uniform node spacing can be rapidly computed, (3) accuracy of computed node values are generally compatible with accuracy and spatial distribution of point data, (4) a relatively large class of nonuniformly spaced node configurations can be computed, (5) data within data-base files can be easily accessed and readily edited, and (6) the occurrence of data processing errors at various stages of data-base generation is monitored by machine contouring the computed grids.</p>\n<p>Functioning of the data-base system is illustrated by the sequence of steps required to produce a model-input array of transmissivity, given raw geologic and hydraulic conductivity data.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri80104","usgsCitation":"Kontis, A., and Mandle, R.J., 1980, Data-base system for northern Midwest regional aquifer-system analysis: U.S. Geological Survey Water-Resources Investigations Report 80-104, iv, 23 p., https://doi.org/10.3133/wri80104.","productDescription":"iv, 23 p.","numberOfPages":"29","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":56941,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1980/0104/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":124967,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1980/0104/report-thumb.jpg"}],"country":"United States","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abde4b07f02db674351","contributors":{"authors":[{"text":"Kontis, A.L.","contributorId":69542,"corporation":false,"usgs":true,"family":"Kontis","given":"A.L.","affiliations":[],"preferred":false,"id":199243,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mandle, Richard J.","contributorId":19956,"corporation":false,"usgs":true,"family":"Mandle","given":"Richard","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":199242,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The model was constructed from available hydrologic data: Records of precipitation, well hydrographs, well logs, two ground-water level surveys, and analyses of six aquifer tests. </p><p>Utilizing this array of data, water levels determined from a series of steady-state simulations of different hydraulic conductivity distributions were calibrated against measured (December 1977) ground-water levels. The simulations that provided the best matches used two hydraulic conductivity distributions: One was an areally varying hydraulic conductivity distribution; the other an areally uniform hydraulic conductivity (40 feet per day) distribution. </p><p>After these more probable hydraulic conductivity distributions were found, they were utilized in steady state maximal pumping simulations. The maximal well-field yield for these simulations was 20.5 million gallons per day for the areally varying hydraulic conductivity distribution, and 11.3 million gallons per day for the areally uniform hydraulic conductivity.

The procedures are applicable to flood flows that are not significantly affected by artificial storage or other manmade activities. For 115 gaged sites within the State, the estimates are from the frequency curves defined from the gaging records. Flood-frequency estimates are made for ungaged sites by using regression relations that require evaluation of the size, main channel slope, and a soil-infiltration index for the drainage basin. Regression relations are considered applicable for estimating flood peaks at sites on basins draining 0.05 to 100 square miles and for estimating flood volumes at sites on basins draining from 0.05 to 15 square miles.</p><p>Limitations on use of the regression relations and the reliability of regression estimates are discussed. A method is indicated for using the estimating procedure and embankment ponding to design smaller highway culverts.</p><p>The procedures were developed from analysis of flood records of 123 gaged sites in South Dakota and adjacent States. For 66 sites, short-term records were extended on the basis of long-term climatic records and a rainfall-runoff model. Linear least-squares regression analyses were used with logarithmic transformation of variables to relate flood magnitudes as dependent variables to indexes describing the drainage basins as independent variables. A dimensionless hydrograph shape was found appropriate for rainfall-runoff hydrographs in South Dakota.</p>","language":"English","publisher":"U.S. Geological

Mapping of outwash sands and gravels delineated two distinct layers of sand and gravel in the southern and eastern parts of the county that merge into one aquifer more than 100 feet thick to the north and west. A digital model that simulates groundwater flow in three dimensions was used to integrate the geologic and hydrologic conditions into a suitable analog of the groundwater system surrounding Fort Wayne. The model consisted of three layers representing (1) the upper till, (2) the upper sand and gravel, and (3) the lower aquifer. The lower aquifer represents a combination of the lower sand and gravel and a section of limestone aquifer immediately underlying the glacial sediments. The model, calibrated against water-level and streamflow data collected during September 1976, was used to simulate pumping and to evaluate the effects of pumping on groundwater levels and streamflows. Two distribution schemes of pumping were tested, each with two different boundary conditions (constant heads and constant flows). The results of these simulated pumping schemes indicate that between 30 and 40 million gallons per day can be produced and that the streamflow losses resulting from this pumping would be between 17 and 25 million gallons per day.

A 1-year study tested the network operation and determined that analysis of the data could demonstrate the major changes in salinity, temperature, and light-attenuation distributions known to occur, based on earlier research, in response to variations of delta inflow and to other physical processes. Observations of eddies at two stations, of the influence of water from a river flooding in the extreme south bay, and of difference in salinity and temperature laterally across the entrance to the south bay are all new but are consistent with existing models. The pH, dissolved oxygen, and light-attenuation measurements, while adequate to observe small-scale vertical variations, are not sufficiently sensitive to detect the effects of phytoplankton blooms.

Basins monitored are in two different geologic and hydrologic environments. Two basins are underlain predominantly by relatively impermeable indurated rocks in the Pottsville Formation of Pennsylvanian age. The two remaining basins are underlain predominantly by unconsolidated permeable rocks in the Coker Formation of Late Cretaceous age. Well yields from the Pottsville Formation generally range from 0 to 0.3 liter per second, whereas well yields from the Coker Formation generally range form 0.3 to 6.4 liters per second. Streamflow distribution reflects seasonal precipitation. Storm runoff is characterized by sharply concentrated flows of short duration that rapidly recede to low-flow conditions. Streams draining basins underlain chiefly by the Pottsville Formation frequently go dry, whereas those draining basins underlain chiefly by the Coker Formation have well sustained low flows. Water in the Pottsville Formation is slightly acidic and moderately hard to very hard. Dissolved solids concentrations ranged from 176 to 268 milligrams per liter. Water in the Coker Formation is soft, far less mineralized, and more acidic than water in the Pottsville. Surface water is generally soft, acidic and low in dissolved solids concentrations. Water in streams draining basins underlain chiefly by the Pottsville Formation was slightly more mineralized and less acidic than water in streams draining the Coker Formation.&nbsp;</p>","language":"English","publisher":"Geological Survey (U.S.)","doi":"10.3133/wri8022","usgsCitation":"Puente, C., Newton, J.G., and Hill, T.J., 1980, Hydrology of selected basins in the Warrior coal field, Alabama — A progress report: U.S. Geological Survey Water-Resources Investigations Report 80-22, vii, 62 p., https://doi.org/10.3133/wri8022.","productDescription":"vii, 62 p.","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":394841,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_35396.htm"},{"id":159124,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1980/0022/report-thumb.jpg"},{"id":92274,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1980/0022/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alabama","otherGeospatial":"Warrior coal field","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.5467,\n              33.327\n            ],\n            [\n              -87.344,\n              33.327\n            ],\n            [\n              -87.344,\n              33.599\n            ],\n            [\n              -87.5467,\n              33.599\n            ],\n            [\n              -87.5467,\n              33.327\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a13e4b07f02db602066","contributors":{"authors":[{"text":"Puente, Celso","contributorId":36140,"corporation":false,"usgs":true,"family":"Puente","given":"Celso","email":"","affiliations":[],"preferred":false,"id":201188,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Newton, John G.","contributorId":22323,"corporation":false,"usgs":true,"family":"Newton","given":"John","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":201187,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hill, Thomas J.","contributorId":13270,"corporation":false,"usgs":true,"family":"Hill","given":"Thomas","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":201186,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

When supporting data from water analyses are available, the value of the cementation exponent m can be determined more precisely. Data for this study were taken from logs of oil-test wells, Amstrat sample studies, drill-stem tests and water test wells in parts of Montana, North and South Dakota, and Wyoming. The preferred resistivity curves for apparent water resistivity (Rwa) analyses are the deeply focused laterolog and the induction log. The standard electric log can be used if the drilling mud is not saturated with salt. The preferred porosity logs are the sonic, sidewall neutron, compensated neutron, and the density logs. Older, uncalibrated neutron curves can be empirically calibrated in some instances, however, resulting porosities are frequently anomalous when compared to those determined from core or modern logs. When apparent water resistivity is determined for many wells, the data can be plotted and contoured to outline areas of recharge, direction of probable ground-water movement, and location and salinity of brine areas.

The way ground-water evapotranspiration varies with depth was modified, and a minimum transmissivity was used to prevent the model from \"going dry\" during water-table simulations.</p>\n<p>Tests of the model showed good correlation with field data, but also showed that certain additional types of information would be useful to make the model more reliable. Particularly helpful would be more water-level and evapotranspiration data, synoptic base-flow measurements in the subbasins, and better information on the variation of permeability and specific yield with depth.</p>\n<p>Predictive simulations made by the model show the effects of imposing various changes on the hydrologic system. Residential development was simulated in 1 square mile of the basin by combinations of the following conditions: 1-acre, 1/2-acre, and 1/4-acre lot size; wastewater disposal by septic systems or by public sewers; domestic wells or public-supply wells for water supply; and 0, 1, and 5 percent reduction in recharge in the developed area. Where water is supplied locally by wells, decreased lot size and reduced recharge result in increased drawdowns and reduced base flow. When wastewater is exported by sewers, these effects are magnified. The simulations by the model show the relative severity of the effects of various development schemes.</p>","language":"English","publisher":"U.S. Geological

The reduced head, already below sea level throughout most of the aquifer system, in conjunction with encroachment of salty water toward centers of pumping, threatens the continued use of the aquifer as a source of freshwater in the area. A single layer, two-dimensional finite difference digital model was used to simulate the response of the aquifer system to pumping stresses during the 18-year period, 1956-73. Model simulations were based on close agreement between (1) observed and calculated heads and head trends for 10 observation wells during the period, 1956-73; and (2) the computed nonpumping steady-state potentiometric surface and a potentiometric surface based on early water-level observations (1900±) solutions. In addition, the hydrologic budget estimated by the model appears to be reasonable for the transient (1956-73) and the steady-state (1900±) solutions. The model was used to compute projected potentiometric heads and trends to the year 2000. Three sets of conditions, all using the 1973 distribution of pumping centers, were simulated. The conditions are:\n(1) no increase in ground-water extractions; (2) continued growth in ground-water extractions at the rate of 1.7 and 3 percent annually; and (3) continued growth in ground-water extractions at the rate of 3 percent annually, in conjunction with the activitation of a freshwater head barrier in the fresh-salty transition zone. Under the first set of conditions, further head reduction would cease over very large regions within two years. Under the second set of conditions involving a 3 percent growth rate similar to that experienced during the simulation period, the broad cone of depression already encompassing most of the New Jersey Coastal Plain would broaden and deepen. Heads would range from 60 to 160 feet below National Geodetic Vertical Datum of 1929. The reduction of head after 1973 would approach 90 feet in some areas. The resultant steeper hydraullic gradients would accelerate the rate of movement of salty ground water toward the pumping centers. A freshwater head barrier could be established in the transition zone to prevent migration of salty ground water across a 35-mile stretch in Gloucester, Camden, and Burlington Counties. A line of injection wells would be required, with total rates of injection to the head barrier ranging from about 56 cubic feet per second in 1984 to about 95 cubic feet per second in 2000. Barrier recharge rates would be equivalent to about 20 percent of the ground water pumped in the fine-grid area in any particular year for a 3 percent increase in extractions.","language":"English","publisher":"U.S. Geological Survey Water Resources Division","publisherLocation":"Trenton, NJ","doi":"10.3133/wri8011","collaboration":"Prepared in cooperation with the New Jersey Department of Environmental Protection, Division of Water Resource","usgsCitation":"Luzier, J.E., 1980, Digital-simulation and projection of head changes in the Potomac-Raritan-Magothy aquifer system, coastal plain, New Jersey: U.S. Geological Survey Water-Resources Investigations Report 80-11, vi, 72 p., https://doi.org/10.3133/wri8011.","productDescription":"vi, 72 p.","numberOfPages":"80","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"links":[{"id":428011,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_35385.htm","linkFileType":{"id":5,"text":"html"}},{"id":267005,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1980/0011/pdf/wrir80-11.pdf"},{"id":267004,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/1980/0011/"},{"id":159627,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_80_11.gif"}],"country":"United States","state":"New Jersey","otherGeospatial":"Potomac-Raritan-Magothy aquifer system","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -75.5420,38.9850 ], [ -75.5420,40.5242 ], [ -73.8501,40.5242 ], [ -73.8501,38.9850 ], [ -75.5420,38.9850 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64ade9","contributors":{"authors":[{"text":"Luzier, James E.","contributorId":102111,"corporation":false,"usgs":true,"family":"Luzier","given":"James","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":199931,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
