Availability of Ground Water in the Branch River Basin, Providence County, Rhode Island

Description: From introduction: This report deals with ground-water resources of the part of the Branch River basin in northwestern Rhode Island upstream from the U.S. Geological Survey gaging station at Forestdale, Rhode lsland, an area of 79 square miles or 205 square kilometers (figure 1). It is one of a series prepared in cooperation with the Rhode Island Water Resources Board to provide quantitative information on the availability of large supplies of ground water in Rhode Island.

Effects of Urbanization on Floods in the Dallas, Texas Metropolitan Area

Description: From abstract: The analyses indicate that in a fully-developed residential area, the flood peaks with be 1.2 to 1.4 times those from an undeveloped area; and the annual direct runoff will be about double that from an undeveloped area. Data were not sufficient to determine the increase in runoff from a highly industrialized area where the effective imperviousness approaches 100 percent.

Evaluating Pollution Potential of Land-Based Waste Disposal Santa Clara County, California -- An Application of Earth-Science Data for Planning

Description: From introduction: As a result of recently initiated programs such as the San Francisco Bay Region Environment and Resources Planning Study, planners in the San Francisco Bay region are becoming increasingly aware of the types and possible uses earth-science data. These data encompasses a wide spectrum of disciplines including hydrology, topography, geology, geomorphology, and seismology. If properly integrated with the planner's competence in demography, sociology, economics, and other fields, earth-science data can be invaluable for evaluating and controlling many critical environment problems in urban areas.

Evaluation of a Proposed Connector Well, Northeastern DeSoto County, Florida

Description: Abstract: At a 24,000-acre citrus grove, a connector well is proposed as a resource management tool for capturing water normally lost through evapotranspiration and by excess runoff. Such a well would connect the surficial sand aquifer with the deep, highly transmissive limestone Floridan Aquifer. Because of natural head differences, water would move by gravity flow from the sand into the Floridan Aquifer, thus replenishing water withdrawn for irrigation from the Floridan Aquifer. A 70-acre marsh was selected as the test site based on analyses of hydraulic conductivity, porosity, and water quality. Recharge rate through the connector well under steady-state conditions is estimated at 160 gallons per minute. The proposed connector well is designed to have 10-inch screens opposite zones in the 45-foot thick sand aquifer, be cased for 400 feet opposite confining beds and a secondary limestone aquifer, and be open hole for about 250 feet in the Floridan Aquifer. A graded-sand filter pack placed around the screened sections of the well will increase its efficiency.

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 aquifer dispersivity and porosity for use in a water-quality model with a large grid interval is under consideration because of the relative insensitivity of such a model to dispersivity. The model results were relevant to the real-life head and water-quality conditions in the aquifer near Barstow and provided an excellent means of evaluating the cause and effect relations associated with ground-water pollution.

Land-Surface Subsidence in the Area of Burnett, Scott, and Crystal Bays Near Baytown, Texas

Description: Abstract: Subsidence in the Baytown area is becoming critical because much of the area is subject to inundation by high tides. Withdrawals of water from industrial wells and declines in artesian pressures began about 1918. As much as 280 feet (85.3 meters) of artesian-head decline has occurred in the Evangeline aquifer, and as much as 320 feet (97.5 meters) of decline has occurred in the Alta Lorna Sand. Subsidence of the land surface began about 1920, and as much as 8.2 feet (2.5 meters) of subsidence had occurred by 1973. Future subsidence was calculated for two loading situations. Case I provided that the artesian heads in the Alta Lorna Sand and Evangeline aquifer would continue to decline at a rate of 6 feet (1.8 meters) per year until 1980. Case II provided that artesian head in the Alta Lorna Sand and Evangeline aquifer would continue to decline at a rate of about 6 feet (1.8 meters) per year until about 1995. The ultimate subsidence expected for the assumed conditions of case I and case II is 11.4 feet (3.47 meters) and 15.1 feet (4.60 meters), respectively.
