A selection of available computer programs for modeling flow and water quality in surface water systems is described. The models include programs developed as part of the U.S. Geological Survey Water Resources Division hydrologic research activities and others developed by other agencies, universities, and consulting firms. Each model description includes...
A geologic evaluation of proposed lava diversion barriers for the NOAA Mauna Loa Observatory, Mauna Loa Volcano, Hawaii
H. J. Moore
1982, Open-File Report 82-314
Lava flow diversion barriers should protect the Mauna Loa Observatory from flows of reasonable magnitude if properly constructed. The a'a flow upon which the observatory is constructed represents a flow of reasonable magnitude. Proper construction of the barriers includes obtaining riprap from a zone exterior to the proposed V-shaped barrier...
Geomorphology of New England
C. S. Denny
1982, Professional Paper 1208
Widely scattered terrestrial deposits of Cretaceous or Tertiary age and extensive nearshore and fluvial Coastal Plain deposits now largely beneath the sea indicate that the New England region has been above sea level during and since the Late Cretaceous. Estimates of rates of erosion based on sediment load in rivers...
A digital-computer model of the Big Sioux aquifer in Minnehaha County, South Dakota
N.C. Koch
1982, Water-Resources Investigations Report 82-4064
A finite-difference digital model was used to simulate steady-state conditions of the Big Sioux aquifer in Minnehaha County. Average water levels and average base flow discharge (4.9 cu ft/s) of the Big Sioux River were based on data from 1970 through 1979. The computer model was calibrated for transient conditions...

Sewage plume in a sand and gravel aquifer, Cape Cod, Massachusetts
Denis LeBlanc
1982, Open-File Report 82-274
Secondarily treated domestic sewage has been disposed of on surface sand beds at the sewage treatment facility at Otis Air Force Base, Massachusetts, since 1936. Infiltration of the sewage through the sand beds into the underlying unconfined sand and gravel aquifer has resulted in a plume of sewage-contaminated ground water...
Digital classification of Landsat data for vegetation and land-cover mapping in the Blackfoot River watershed, southeastern Idaho
L. R. Pettinger
1982, Professional Paper 1219
This paper documents the procedures, results, and final products of a digital analysis of Landsat data used to produce a vegetation and landcover map of the Blackfoot River watershed in southeastern Idaho. Resource classes were identified at two levels of detail: generalized Level I classes (for example, forest land and...
Sulfur isotopic composition and water chemistry in water from the High Plains aquifer, Oklahoma Panhandle and southwestern Kansas
Noel C. Krothe, Joseph W. Oliver
1982, Water-Resources Investigations Report 82-12
The Ogallala Formation comprises the High Plains aquifer in Oklahoma and southwestern Kansas. Regional ground-water flow is from west to east in the Ogallala Formation, and the concentration of dissolved solids in ground water increases in the direction of flow. This increase may be influenced by residence time, but underlying...
Potential hydrologic impacts of ground-water withdrawal from the Cape Cod National Seashore, Truro, Massachusetts
Denis R. LeBlanc
1982, Open-File Report 82-438
The hydrologic impacts of continuous ground-water withdrawals at 0.75, 1.0, and 1.24 Mgal/d (million gallons per day) from a test-well site in the Cape Cod National Seashore, Truro, Massachusetts, were evaluated with a three-dimensional finite-difference steady-state-flow digital model. The digital model was prepared during an earlier study and is only...

Ground-water monitoring at Santa Barbara, California; Phase 2-effects of pumping on water levels and water quality in the Santa Barbara ground-water basins
Peter Martin
1982, Open-File Report 82-366
From July 1978 to January 1980, water levels declined more than 100 feet in the southern part of the Santa Barbara ground-water basin. The water-level declines are the result of increases in municipal pumping since July 1978. The increase in municipal pumping was part of a basin-testing program to determine...

Perennial-streamflow characteristics related to channel geometry and sediment in Missouri River basin
W. R. Osterkamp, E. R. Hedman
1982, Professional Paper 1242
Geometry, channel-sediment, and discharge data were collected and compiled from 252 streamflow-gaging stations in the Missouri River basin. The sites represent the complete ranges of hydrologic and geologic conditions found in the basin. The data were analyzed by computer to yield equations relating various discharge characteristics to variables of channel...
Effects of flooding upon woody vegetation along parts of the Potomac River flood plain
T.M. Yanosky
1982, Professional Paper 1206
A two-part study along the Potomac River flood plain near Washington, D.C., was undertaken to investigate the effects of flooding upon woody vegetation. Floods abrade bark, damage branches and canopies, and often uproot trees. The first study was of vegetation in five monumented flood-plain plots which differed in the frequency...
