A method for estimating magnitude and frequency of floods in South Dakota
Lawrence D. Becker
1974, Water-Resources Investigations Report 74-35
A general flood-frequency analysis has provided a method for estimating flood magnitudes and frequencies on South Dakota streams. Related flood data useful in planning and design also are included in the report.Two distinct hydrologic regions are delineated within the State. The divisional boundary for these regions is, in general, the...
The 1971 drought in South Florida and its effect on the hydrologic system
Manuel A. Benson, Richard Alfred Gardner
1974, Water-Resources Investigations Report 74-12
The 1971 dry season rainfall in south Florida was low enough that the public media and concerned public officials unanimously characterized the event as a severe drought.Rainfall over all of south Florida during the 1970 wet season and the 1970-71 dry season was less than 85 percent of normal, as...
Estimated permeabilities for soils in the Sacramento Valley, California
Gilbert L. Bertoldi
1974, Water-Resources Investigations Report 73-51
Analysis of engineering and hydrologic data from 15 previous soil studies, analysis of particle-size distribution, and analysis of descriptions of soil profiles show that 50 percent of the Sacramento Valley area has soils having permeabilities characterized by infiltration rates of less than 2 feet per day (0.6 meter per day)....

Hydrologic analysis of the Mojave River, California, using a mathematical model
Timothy J. Durbin, W. F. Hardt
1974, Water-Resources Investigations Report 74-17
The channel of the Mojave Rive'r in California is normally dry and is highly permeable over much of its length, and large quantities of water from natural floodflows in the channel infiltrate through the channel bed to the underlying ground-water body. From 1930 to 1972 only 18 floods at The...
Water quality of hydrologic bench marks; an indicator of water quality in the natural environment
James E. Biesecker, Donald K. Leifeste
1974, Circular 460-E
Water-quality data, collected at 57 hydrologic bench-mark stations in 37 States, allow the definition of water quality in the 'natural' environment and the comparison of 'natural' water quality with water quality of major streams draining similar water-resources regions. Results indicate that water quality in the 'natural' environment is generally very...
Geologic and hydrologic considerations for various concepts of high-level radioactive waste disposal in conterminous United States
E. B. Ekren, G.A. Dinwiddie, J. W. Mytton, William Thordarson, J. E. Weir Jr., E. N. Hinrichs, L.J. Schroder
1974, Open-File Report 74-158
The purpose of this investigation is to evaluate and identify which geohydrologic environments in conterminous United States are best suited for various concepts or methods of underground disposal of high-level radioactive wastes and to establish geologic and hydrologic criteria that are pertinent to high-level waste disposal. The unproven methods of...

Floodflow characteristics of Fourche Creek at Interstate Highway 430, in southwest Little Rock, Arkansas
R.C. Gilstrap, J.N. Sullavan
1974, Open-File Report 74-343
The Arkansas State Highway Department is constructing Interstate Highway 430 (1-430) across Fourche Creek in southwest Little Rock. The Highway Department requested the U.S. Geological Survey to determine the elevation, the discharge, and the frequency of the flood of April 21, 1974, and the elevation, the discharge, and the backwater...

1974, Open-File Report 74-196
The Sahelian Zone Remote Sensing Seminar/Workshop held in Bamako, Mali, April 17-28, 1973. The Government of Mali was host. The Agency for International Development sponsored and funded, and the U. S. Geological Survey prepared and presented the program. Thirteen countries and seven commissions were invited. Thirty-five scientists and management personnel...
Hydrologic data of the Hoosic River basin, Massachusetts
Bruce P. Hansen, Frederick B. Gay, L.G. Toler
1974, Open-File Report 74-368
The Hoosic River has its headwaters in northwestern Massachusetts and southern Vermont and flows northwestward through southern Vermont into New York, where it is tributary to the Hudson River. Upstream from the Massachusetts State line the Hoosic River drains a total of 205 mi2 (531 km2) of which 164 mi2...

Erosion and sediment yields in mountain watersheds of the Transverse Ranges Ventura and Los Angeles Counties, California; analysis of rates and processes
Kevin M. Scott, Rhea P. Williams
1974, Water-Resources Investigations Report 73-47
Major-storm and long-term erosion rates in mountain watersheds of the western Transverse Ranges of Ventura County are estimated to range from low values that will not require the construction of catchments or channel-stabilization structures to values as high as those recorded anywhere for comparable bedrock erodibilities.A major reason for this...
Analog-model studies of ground-water hydrology in the Houston District, Texas
Donald G. Jorgensen
1974, Open-File Report 74-113
The major water-bearing units in the Houston district are the Chicot and the Evangeline aquifers. The Chicot aquifer overlies the Evangeline aquifer, which is underlain by the Burkeville confining layer. Both aquifers consist of unconsolidated and discontinuous layers of sand and clay that dip toward the Gulf of Mexico. Heavy...
