Land-Surface Subsidence at Seabrook, Texas

Description: Abstract: Removal of water, oil, and gas from the subsurface in Harris and Galveston Counties, Texas, has caused a decline in fluid pressures, which in turn has resulted in subsidence of the land surface. Subsidence of the land surface at Seabrook is due principally to the removal of water. Significant subsidence of the land surface probably began after 1920, and a minimum of about 3.3 feet (1.0 m) and a maximum of about 4.3 feet (1.3 m) of subsidence had occurred at Seabrook by 1973. Probable … more

Hydrologic Relations Between Lakes and Aquifers in a Recharge Area near Orlando, Florida

Description: Abstract: The three lakes investigated gain water- from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents hydraulic gradient between lake and water-table aquifer, A is lumped parameter representing effect of hydaulic conductivity and cross-sectional area of materials in flow section of water-table aquifer, Y is head diff… more

Waterlogging in an Alluvial Aquifer near Lake Minnequa, Pueblo, Colorado

Description: Abstract: The Lake Minnequa area, located immediately south of the Arkansas River, is mantled with as much as 46 feet (14 meters) of alluvium covering bedrock of Pierre Shale and Niobrara Formation. Surface water enters the area by the Minnequa Canal and the St. Charles Flood Ditch. The water is stored in Lake Minnequa and other reservoirs. Seepage from St. Charles Reservoirs No. 2 and No. 3 is the major source of water to the alluvial aquifer. The depth of the water table ranges from 0 to 40 f… more

Water Resources of the North Coast Limestone Area, Puerto Rico

Description: From introduction: The North Coast Limestone area is one of the two most important ground-water provinces of Puerto Rico--the other being the South Coast Alluvial aquifer. The investigation of the water resources of the South Coast has progressed to the point that at this time (mid-1971) an electric-analog model of the area is being prepared. The hydrology of the North Coast Limestones, however, was never investigated as a whole before this investigation, and, therefore, this study was designed… more

WATEQF: A FORTRAN IV Version of WATEQ, a Computer Program for Calculating Chemical Equilibrium of Natural Waters

Description: Abstract: WATEQF is a FORTRAN IV computer program that models the thermodynamic speciation of inorganic ions and complex species in solution for a given water analysis. The original version (WATEQ) was written in 1973 by A. H. Truesdell and B. F. Jones in Programming Language/one (PL/1). With but a few exceptions, the thermochemical data, speciation, activity coefficients, and general calculation procedure of WATEQF is identical to the PL/1 version. This report notes the differences between WAT… more

Technique for Estimating Magnitude and Frequency of Floods in Kentucky

Description: Abstract: This report presents flood magnitude and frequency relations applicable to 'unregulated streams in Kentucky. The relations are based on flood data at 117 gaging stations in Kentucky and 14 in adjacent states having 10 or more years of record not significantly affected by man-made changes . Equations that relate flood magnitude and frequency to contributing drainage area in 16 geographic areas may be used to estimate magnitude of future floods with recurrence intervals of as much as 10… more

Land-Surface Subsidence in the Area of Moses Lake Near Texas City, Texas

Description: Abstract: Removal of water, oil, and gas from the subsurface in Harris and Galveston Counties has caused declines in fluid pressures, which in turn have resulted in subsidence of the land surface. Subsidence of the land surface at Moses Lake is due principally to the removal of ground water in adjacent areas. Significant subsidence of the land surface at Moses Lake began after 1900, and as much as 1.8 feet (0.55 meters) of subsidence had occurred in the area by 1973. Probable future subsidence … more

Preimpoundment Water Quality of Raystown Branch Juniata River and Six Tributary Streams, South-Central Pennsylvania

Description: Abstract: The Raystown Branch Juniata River watershed, which is the main water source for Raystown Lake, is a 960-square-mile (2,490 square kilometers) drainage basin in south-central Pennsylvania. Preimpoundment water-quality data were collected on the Raystown Branch and six tributary streams in the basin. Specific conductance values varied inversely with water discharge. The pH values were extremely low only at the Shoup Run site. Dissolved oxygen concentrations observed at all sites indicat… more

Availability of Ground Water near Carmel, Hamilton County, Indiana

Description: Abstract: Flow in the unconsolidated glacial deposits near the city of Carmel in central Indiana was simulated by a digital-computer model in a study of hydraulic characteristics of the deposits. The study shows that 21 • 3 million gallons per day (933 liters per second) of additional water could be withdrawn from the aquifer for an indefinite period of time. This pumpage is approximately 5 million gallons per day (219 liters per second) above the projected water needs of Carmel for 1990. Satur… more
