The hydrodynamics of the Big Horn basin: A study of the role of faults
A three-dimensional mathematical model simulates virgin groundwater flow in the Big Horn basin, Wyoming. The computed results are compared to two published interpretations of the Tensleep Sandstone virgin potentiometric surface; both of these interpretations, Bredehoeft and Bennett, and Haun, were made from the same data set. The published maps are quite different. Bredehoeft and Bennett ignored t

Numerical simulation of ground-water flow in the central part of the western San Joaquin Valley, California
The occurrence of selenium in agricultural drain-water in the central part of the western San Joaquin Valley, California, has focused concern on strategies for managing shallow, saline ground water. In order to assess alternatives to agricultural drains, a three-dimensional, finite-difference numerical model of the regional ground-water flow system was developed. This report documents the mathemat

Simulation of water-table response to management alternatives, central part of the western San Joaquin Valley, California
The occurrence of selenium in agricultural drainwater in the central pan of the western San Joaquin Valley, California, has focused concern on alternatives other than agricultural drains for managing shallow, poor-quality ground water. A transient, three-dimensional, finite-difference ground-water flow model was developed to assess the response of the water table to various management alternatives

Calibration of a texture-based model of a ground-water flow system, western San Joaquin Valley, California
The occurrence of selenium in agricultural drain water from the western San Joaquin Valley, California, has focused concern on the semiconfined ground-water flow system, which is underlain by the Corcoran Clay Member of the Tulare Formation. A two-step procedure is used to calibrate a preliminary model of the system for the purpose of determining the steady-state hydraulic properties. Horizontal a

Distribution of wells in the central part of the western San Joaquin Valley, California
Information from 5,860 wells in the central part of the western San Joaquin Valley, California, was collected from several sources and compiled into a common data base. Only 2,547 wells had sufficient information for classification into four categories based on the hydrogeology: wells perforated in the semiconfined zone at depths less than or equal to 50 ft, wells perforated in the semiconfined zo

Texture and depositional history of near-surface alluvial deposits in the central part of the western San Joaquin Valley, California
Saline conditions and associated high levels of selenium and other soluble trace elements in soil, shallow ground water, and agricultural drain water of the western San Joaquin Valley, California, have prompted a study of the texture of near-surface alluvial deposits in the central part of the western valley. Texture is characterized by the percentage of coarse-grained sediment present within a sp

Lateral fluid flow in a compacting sand-shale sequence: South Caspian basin
The South Caspian basin contains both sands and shales that have pore-fluid pressures substantially in excess of hydrostatic fluid pressure. Pore-pressure data from the South Caspian basin demonstrate that large differences in excess hydraulic head exist between sand and shale. The data indicate that sands are acting as drains for overlying and underlying compacting shales and that fluid flows lat

Character and evolution of the ground-water flow system in the central part of the western San Joaquin Valley, California
The occurrence of selenium in agricultural drain water derived from the western San Joaquin Valley, California, has focused concern on the ground-water flow system of the western valley. In this investigation, previous work and recently collected texture and water-level data are used to evaluate the character and evolution of the regional ground-water flow system in the central part of the western

Hydrodynamics of Denver basin: Explanation of subnormal fluid pressures
Anomalously low fluid potential (and hence subnormal fluid pressure) is found in Mesozoic and Paleozoic rocks of the Denver basin. The potentiometric surface for the Dakota and basal Cretaceous sandstones is 2,000-3,000 ft (600-900 m) beneath the land surface in parts of the Denver basin in Colorado and Nebraska. The potentiometric surface for pre-Pennsylvanian carbonate rocks is 1,500 ft (450 m)
