Reconnaissance geology of the Jibal Matalli Quadrangle, sheet 27/40 D, Kingdom of Saudi Arabia
E. B. Ekren
1984, Open-File Report 84-378
The Jibal Matalli quadrangle lies along the northern boundary of the Arabian Shield about 90 km west-southwest of Ha'il. The quadrangle consists of about 45 percent Precambrian bedrock, 50 percent Quaternary deposits, and 5 percent sedimentary cover rocks. The Precambrian rocks include volcaniclastic and volcanic rocks that are slightly metamorphosed...
A ground-water-quality monitoring network for the Lower Mojave River Valley, California
L. R. Woolfenden
1984, Water-Resources Investigations Report 83-4148
A ground-water-quality monitoring network was developed for the Lower Mojave River valley to define the ground-water quality of the valley. Basin geohydrology, geology, land use and water-level and water-quality data were factors considered in developing objectives for an ideal network. These objectives were used in selecting well locations for the...
Evaluation of alternative reservoir-management practices in the Rock River basin, Wisconsin
W.R. Krug, L. B. House
1984, Water-Resources Investigations Report 83-4186
Simulation of the operation of upstream impoundments in the Rock River basin to reduce spring floods showed that such operation would reduce flood peaks by 0.11 foot on the average, and would increase flood peaks some years. The most significant reductions would occur during the average- size floods, whereas little...
Reconnaissance geology of the Qufar Quadrangle, sheet 27/41 D, Kingdom of Saudi Arabia
K.S. Kellogg
1984, Open-File Report 84-159
The Qufar quadrangle, south of the city of Ha' il in the northern Arabian Shield is underlain by late Proterozoic granitic and dioritic rocks and two volcano-sedimentary sequences. Phanerozoic rocks include a few outcrops of the Cambrian and Ordovician Saq Sandstone and small remnants of Miocene basalt flows and plugs. The...
Annual water-resources review, White Sands Missile Range, New Mexico, 1983
R. R. Cruz
1984, Open-File Report 84-720
Ground-water data were collected at White Sands Missile Range in 1983. The total amount of water pumped from White Sands Missile Range supply wells in 1983 was 713,557,500 gallons. The Post Headquarters well field accounted for 686,499,200 gallons of the total. Seasonal water-level fluctuations in the supply wells ranged from...
Carbonate geology and hydrology of the Edwards Aquifer in the San Antonio area, Texas
R.W. Maclay, T. A. Small
1984, Open-File Report 83-537
Regional differences in the porosity and permeability of the Edwards aquiifer are related to three major depositional areas, the Maverick basin the Devils River trend, and the San Marcos platform, that existed during Early Cretaceous time. The rocks of the Maverick basin are predominantly deep basinal deposits of dense, homogeneous...
