The Brazos Valley Groundwater Conservation District: A Case Study in Texas Groundwater Conservation

Description: This thesis examines the history of groundwater management through the development of groundwater conservation districts in Texas. Political, economic, ideological, and scientific understandings of groundwater and its regulation varied across the state, as did the natural resource types and quantities, which created a diverse and complicated position for lawmakers and landowners. Groundwater was consistently interpreted as a private property right and case law protected unrestricted use for the… more

Three-Dimensional Digital-Computer Model of the Principal Ground-Water Reservoir of the Sevier Desert, Utah

Description: Abstract: A three-dimensional finite-difference digital model was used to simulate the principal ground-water reservoir of the Sevier Desert. The model was calibrated against steady-state water levels, aquifer tests, and measured water-level changes from 1952 to 1982. The calibrated model can be used to project future water-level changes assuming various ground-water development options.

Ground Water in the Northeast Part of Twentynine Palms Marine Corps Base, Bagdad Area, California

Description: Purpose and scope: The U.S. Marine Corps conducts training maneuvers in the study area. Lack of a local source of water has severely limited the utilization of the area. In the past, limited quantities of water have been transported to the area by truck or helicopter. The purpose of this study was to determine the feasibility of obtaining a supply of ground water in the area for use when field maneuvers are being conducted. The major effort for this study was concentrated on the part within the… more

The Effects of Channel Excavation on Water-Quality Characteristics of the Black River and on Ground-Water Levels Near Dunn, North Carolina

Description: From abstract: Data were collected at three sites on the Black River near Dunn, North Carolina, to define the effects of channel excavation on water-quality characteristics and on ground-water levels in nearby areas. Background data were collected at a site upstream from the 5-mile-long excavated reach. Changes in hydrologic characteristics were determined from data collected before, during, and after the construction period 1976-81. Significant changes occurred in shallow ground-water levels, … more

Estimating 1980 Ground-Water Pumpage for Irrigation on the High Plains in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

Description: From introduction: This report describes the results of 1980 sampling of ground-water pumpage for irrigation on the High Plains, one phase of the High Plains Regional Aquifer-System Analysis project. These data were collected to estimate the volume of irrigation water pumped during 1980 and to determine current trends in irrigation pumpage on the High Plains.

Modifications and Corrections to the Finite-Difference Model for Simulation of Three-Dimensional Ground-Water Flow

Description: From abstract: This report describes modifications that are incorporated into the finite-difference model for simulation of ground-water flow in three dimensions by Trescott, and Trescott and Larson. [It] also describes corrections to the model that eliminate errors in the equation formulation and in mass-balance computations for certain types of simulations.

A New Approach to Texas Groundwater Management: An Environmental Justice Argument to Challenge the Rule of Capture

Description: Texas is the last remaining state to utilize the rule of capture, a doctrine based on English Common Law, as a means of regulating groundwater resources. Many of the western states originally used the rule of capture to regulate their groundwater resources, but over time, each of these states replaced the rule of capture with other groundwater laws and regulations. The Texas Water Development Board (TWDB) State Water Plan, Water for Texas-2002, warned Texans if current water usage and laws d… more

Comparison of Remediation Methods in Different Hydrogeologic Settings Using Bioplume II

Description: A contaminant fate and transport computer model, Bioplume II, which allows simulation of bioremediation in ground water systems, was used to compare the effects of 11 remediation scenarios on a benzene plume. The plume was created in three different hydrogeologic settings from the simulation of an underground gasoline storage tank leak.

Feasibility of Digital Water-Quality Modeling Illustrated by Application at Barstow, California

Description: Abstract: A digital water-quality model of the shallow alluvial aquifer near Barstow was evaluated to determine the applicability of the model computer program to varied hydrolic problems. The evaluation was made on the basis of the data requirements of the model, the characteristics and limitations of the model computer program, the relevance of the model results, and the computer costs associated with the model. Two-well tracer-dilution tests may not be a workable means of determining the aqu… more

DIFFERENTIAL GROUP-VELOCITY DETECTION OF FLUID PATHS

Description: For nearly 50 years, surface waves that propagate through near-surface soils have been utilized in engineering for the determination of the small-strain dynamic properties of soils. These techniques, although useful, have not been sufficiently precise to use in detecting the subtle changes in soil properties that accompany short-term changes in fluid content. The differential techniques developed in this research now make it possible to monitor small changes (less than 3 cm) in the water level … more
