Simulation studies of flow and sediment transport using a mathematical model, Atchafalaya River Basin, Louisiana
Marshall E. Jennings, Larry F. Land
1977, Water-Resources Investigations Report 77-14
Simulation studies were made of flow and sediment transport for the Atchafalaya River basin, Louisiana using a mathematical model calibrated and supplied by the Hydrologic Engineering Center and the New Orleans District, U.S. Army Corps of Engineers. The study results are based on three, 50-year computer simulations for the following...

Water quality of selected streams in the coal area of southeastern Montana
J. R. Knapton, P. W. McKinley
1977, Water-Resources Investigations Report 77-80
This report summarizes and evaluates water-quality data collected at 35 stream sites the the coal region of southeastern Montana. Sarpy Creek, Armells Creek, and Rosebud Creek sometimes have dissolved-solids concentrations that cause water to be marginal for agricultural purposes. At times of rainfall and snowmelt, the runoff water mixes with...
Water and related problems in coal-mine areas of Alabama
Alfred L. Knight, John G. Newton
1977, Water-Resources Investigations Report 76-130
Water-resource problems or potential problems in Alabama resulting from surface and subsurface coal mining include erosion and sedimentation, flooding, diversion of drainage, decline in water level, land subsidence, and the degradation of water quality. The degradation of water quality is the most serious and widespread coal-mine related problem in Alabama....
Ground water in the Koehn Lake area, Kern County, California
J. H. Koehler
1977, Water-Resources Investigations Report 77-66
Hydrologic characteristics of the Koehn Lake area were investigated to determine the effects of external stresses on the system. Unconsolidated deposits are more than 900 feet thick in the central part of the basin. Cantil Valley fault, in the central part of the basin, acts as a barrier to the...

Ground-water resources of the alluvial aquifers in northeastern Larimer County, Colorado
R. T. Hurr, P.A. Schneider
1977, Water-Resources Investigations Report 77-7
Ground water is a source of municipal, domestic, stock, and irrigation supply for most of northeastern Larimer County, Colo. A study of the alluvial aquifers in the northeastern part of the county was conducted to determine volume of water in storage, rate and location of ground-water withdrawals, and chemical quality...

Water-level changes in wells along the west side of the Cedar Creek anticline, southeastern Montana
D.L. Coffin, T.E. Reed, S.D. Ayers
1977, Water-Resources Investigations Report 77-93
Water levels have been measured periodically in wells along the west side of the Cedar Creek anticline in southeastern Montana since 1962-64. The measurements show the response of the Fox Hills-Hell Creek aquifer of Late Cretaceous age to withdrawals for domestic, stock, and industrial uses. Water levels were as much...
Computation of records of streamflow at control structures
Dannie L. Collins
1977, Water-Resources Investigations Report 77-8
Traditional methods of computing streamflow records on large, low-gradient streams require a continuous record of water-surface slope over a natural channel reach. This slope must be of sufficient magnitude to be accuratly measured with available stage measuring devices. On highly regulated streams, this slope approaches zero during periods of low...

Low-flow characteristics of Minnesota streams
K.L. Lindskov
1977, Water-Resources Investigations Report 77-48
Low-flow frequency data for 161 continuous-record gaging stations having eight or more complete years of record are presented for 1-, 7-, 14-, 30-, 60-, 90-, 120-, 183-, and 365-day low flows for frequencies ranging from once in 2 years to once in 100 years. In addition, 8,146 low-flow measurements at...
Water resources data for West Virginia, water year 1975
Water Resources Division, U.S. Geological Survey
1977, Water Data Report WV-75-1
Water resources data for the 1975 water year for West Virginia consist of records of stage, discharge, and water quality of streams and springs; stage and contents of lakes and reservoirs; and water levels in wells. This report contains discharge records for 131 gaging stations; stage only records for 1...
Floods of November 12, 1974 in the Charlotte Amalie area, St Thomas, US Virgin Islands
W.J. Haire, K. G. Johnson
1977, Water-Resources Investigations Report 76-91
The flood on St. Thomas, U.S. Virgin Islands, of November 12, 1974, was the largest recorded flood in the area from Fort Christian through Charlotte Amalie and Frenchtown to the end of Crown Bay. This flood has a recurrence interval of about 60 years. With the exception of a few...
Availability of ground water in the lower Merrimack River basin southern New Hampshire
J. E. Cotton
1977, Water-Resources Investigations Report 77-69
This map, scale 1:125,000, is a preliminary assessment of the availability of ground water in the lower Merrimack River basin in southern New Hampshire. It is a generalization of several hydrogeologic factors and provides a guideline for ground-water exploration, which is useful in water- and land-use planning. It does not...
Availability of ground water in the Piscataqua and other coastal river basins southeastern New Hampshire

This map (scale 1:125,000) is a preliminary assessment of the availability of ground water in the Piscataqua and coastal river basins in New Hampshire. It is a generalization of several hydrogeologic factors and provides a guide for ground-water exploration, which is useful in water- and land-use planning. The best aquifers...
Digital model analysis of the principal artesian aquifer, Savannah, Georgia area
H. B. Counts, R.E. Krause
1977, Water-Resources Investigations Report 76-133
A digital model of the principal artesian aquifer has been developed for the Savannah, Georgia, area. The model simulates the response of the aquifer system to various hydrologic stresses. Model results of the water levels and water-level changes are shown on maps. Computations may be extended in time, indicating changes...
