Floods of August and September 1971 in Maryland and Delaware
D.H. Carpenter
1974, Open-File Report 74-1015
Intense rainfall, resulting mostly from severe thunderstorms in August and September 1971 caused considerable flooding throughout much of Maryland and Delaware. Precipitation totals of 5.47 inches in 3 hours and 12.6 inches in 12 hours were reported for the most severe storm of the period which occurred on Aug. 1-2,...
Grid-coordinate generation program
Oliver J. Cosner, Esther Horwich
1974, Open-File Report 74-1018
This program description of the grid-coordinate generation program is written for computer users who are familiar with digital aquifer models. The program computes the coordinates for a variable grid -used in the 'Pinder Model' (a finite-difference aquifer simulator), for input to the CalComp GPCP (general purpose contouring program). The program...
Characteristics of streamflow and ground-water conditions in the Boise River Valley, Idaho
C.A. Thomas, N. P. Dion
1974, Water-Resources Investigations Report 74-38
The quantity, quality, and distribution in time of streamflow in Boise River below Lucky Peak Lake are drastically affected by storage reservoirs, diversions for irrigation, and by domestic, industrial, and agricultural wastes. Reservoirs usually fill during the nonirrigation season, and streamflow for several miles below Lucky Peak Lake is very...
The quality of surface waters in Texas
Jack Rawson
1974, Water-Resources Investigations Report 74-7
The discharge-weighted average concentrations of dissolved solids, chloride, and ,sulfate for many of the principal streams in Texas are less than 500 mg/l (millijgraljls per liter), 250 mg/l, and 250 mg/l, respectively. At 65 of 131 sites on streams that were sampled at least 10 times, the biochemical oxygen demand...
Hydrologic- and salt-balance investigations utilizing digital models Lower San Luis Rey River area, San Diego County, California
Joe A. Moreland
1974, Water-Resources Investigations Report 74-24
The Joint Administration Committee of the Santa Margarita and San Luis Rey Watershed Planning Agencies was designated as the agency to conduct studies leading to the development of a comprehensive water-quality management plan for the two watersheds. Hydrologic and salt balances for the Pauma, Pala, Bonsall, and Mission ground-water basins...
The effect of heated water on the temperature and evaporation of Hyco Lake, North Carolina, 1966-72
W.L. Yonts, G. L. Giese
1974, Water-Resources Investigations Report 74-11
Three levels of thermal loading of Hyco Lake by heat from two steam-electric generators have resulted in higher temperatures and increased evaporation in the 3,750-acre (1,518 square hectometer) lake. During the winter, local temperature increases of 34°F (19°C) were sometimes observed at the surface as heated water spread out on...
Flood profiles and inundated areas along the White River, Chelan County, Washington
John Savini, C.F. Schneider, D.E. LaFrance
1974, Water-Resources Investigations Report 74-13
Flood profiles covering the main stem to river mile 11.0 (kilometer 17.7) of the White River in Chelan County, Wash., were developed in a 3-year field study (1970-72) in cooperation with the State of Washington Department of Ecology. Flood-frequency curves based on an average of a regional computation and a...
Empirical data on longitudinal dispersion in rivers
Carl F. Nordin, George V. Sabol
1974, Water-Resources Investigations Report 74-20
Empirical data on longitudinal dispersion process in rivers are compiled from published and unpublished sources. Fifty-one sets of data, covering flows from about 30 cubic feet per second to 241,000 cubic feet per second (0.85 to 6,820 cubic meters per second), are analyzed graphically....
Flood characteristics of Oklahoma streams techniques for calculating magnitude and frequency of floods in Oklahoma, with compilations of flood data through 1971
Vernon B. Sauer
1974, Water-Resources Investigations Report 73-52
The 2-, 5-, 10-, 25-, 50-, and 100-year recurrence interval floods are related to basin and climatic parameters for natural streams in Oklahoma by multiple regression techniques through the mathematical model, Qx=aAbScPd,where Qx is peak discharge for recurrence interval x, A is contributing drainage area, S is main channel slope,...
An approach to estimating flood frequency for urban areas in Oklahoma
Vernon B. Sauer
1974, Water-Resources Investigations Report 74-23
Flood-frequency studies for urban areas in several parts of the United States and flood-frequency relations for natural streams of Oklahoma were used to develop a set of flood-frequency equations for urban areas of Oklahoma. Equations arepresented for estimating the 2-, 5-, 10-, 25-, 50-, and 100-year flood-peak discharges for basins...
Index to maps of flood-prone areas in Indiana
William G. Weist Jr.
1974, Water-Resources Investigations Report 74-48
A listing of flood maps for Indiana prepared by the U.S. Geological Survey through 1974 is presented by county. The list provides information on the type of flooding depicted and the reliability of the delineation.The list was prepared from a computer file, and an available program allows retrieval of data...
Oak Glen water-resources development study using modeling techniques, San Bernardino County, California
William R. Powers III, William F. Hardt
1974, Water-Resources Investigations Report 74-31
Hydrologic, digital-model, and economic analyses were made to determine the most efficient balance of conjunctive use of local ground water and surface water--specifically, whether additional ground-water supplies can be developed in the Oak Glen study area, San Bernardino County, Calif., for local use and also for export to the adjacent...
Seawater intrusion, ground-water pumpage, ground-water yield, and artificial recharge of the Pajaro Valley area, Santa Cruz and Monterey Counties, California
K. S. Muir
1974, Water-Resources Investigations Report 74-9
The Pajaro Valley area, California, covering about 120 square miles (310 km2), extends from the southern part of Santa Cruz County to several miles south of the county line into Monterey County. It borders the Pacific Ocean on the west and the Santa Cruz Mountains on the east. The city...
