Digital modeling of radioactive and chemical waste transport in the Snake River plain aquifer at the National Reactor Testing Station, Idaho
J.B. Robertson
1974, Open-File Report 74-1089
Industrial and low-level radioactive liquid wastes at the National Reactor Testing Station (NRTS) in Idaho have been disposed to the Snake River Plain aquifer since 1952. Monitoring studies have indicated that tritium and chloride have dispersed over a 15-square mile (39-square kilometer) area of the aquifer in low but detectable...

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...

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...
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...

Mathematical model of San Juan Valley ground-water basin, San Benito County, California
Robert E. Faye
1974, Water-Resources Investigations Report 73-58
A mathematical model study of the San Juan Valley ground-water basin in San Benito County, Calif., has quantitatively described the ground-water hydrology of the basin under past, present, and future conditions of development. An analysis of conditions in the basin prior to large-scale ground-water development indicates that net recharge equaled...
Flood characteristics of Oklahoma streams techniques for calculating magnitude and frequency of floods in Oklahoma, with compilations of flood data through 1971

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,...
Estimating low-flow frequency for perennial Missouri Ozarks streams
John Skelton
1974, Water-Resources Investigations Report 73-59
A linear regression model, utilizing an independent variable described as the flow area of a stream, has been developed for use in estimating minimum streamflow at ungaged sites in the Ozarks region of Missouri. The basic premise in the method is that low-flow characteristics at any point on perennial Ozarks...
