Summary appraisals of the nation's ground-water resources – Caribbean region
Fernando Gómez-Gómez, James E. Heisel
1980, Professional Paper 813-U
The Caribbean Region consists of the Commonwealth of Puerto Rico (8,990 km2 (square kilometers)) and the U.S. Virgin Islands (350 km2). The mean annual precipitation varies locally from a high of 5,000 mm (millimeters) to a low of 730 mm. Maximum precipitation occurs within the peaks of Sierra de Luquillo,...
Temperature and solute-transport simulation in streamflow using a Lagrangian reference frame
Harvey E. Jobson
1980, Water-Resources Investigations Report 81-2
A computer program for simulating one-dimensional, unsteady temperature and solute transport in a river has been developed and documented for general use. The solution approach to the convective-diffusion equation uses a moving reference frame (Lagrangian) which greatly simplifies the mathematics of the solution procedure and dramatically reduces errors caused by...
Maps showing coal resources of the Jewell Bridge Quadrangle, Buchanan and Tazewell counties, Virginia
Kenneth J. Englund, Nancy K. Teaford
1980, Miscellaneous Field Studies Map 1211
Coal of low-volatile to high-volatile A bituminous rank is the principal developed mineral resource in the Jewell Ridge quadrangle.  The coal beds in the Jewell Ridge quadrangle contain total estimated original resources of 1,519 million tons.  Of this total, 108 million tons have been mined or lost in mining, leaving...
Geology and ground water in north-central Santa Cruz County, California
Michael J. Johnson
1980, Water-Resources Investigations Report 80-26
North-central Santa Cruz County is underlain mainly by folded sedimentary rocks of Tertiary and Cretaceous age that have been highly fractured by movements in the San Andreas fault system. Ground water is stored in fractures within shale and mudstone formations and in intergranular pore spaces within fine- to very fine-grained...
Investigation of artificial recharge of aquifers in Nebraska
William F. Lichtler, David I. Stannard, Edwin Kouma
1980, Water-Resources Investigations Report 80-93
Large withdrawals of ground water for irrigation are causing progressive declines of ground-water levels in some areas of Nebraska. An investigation was conducted to determine the technical feasibility of artificially recharging aquifers through wells and through surface spreading by means of impoundments, pits, and canals. Information gained from a literature...
Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, Hurricane quadrangle, Alabama
John C. Scott, Larry R. Bohman
1980, Hydrologic Atlas 629
Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the Mobile and Tensaw Rivers in Mobile and Baldwin Counties, Alabama. Most of the inundated areas shown are marshlands or flood plains of small tributary streams. Storm-tides frequency and...
Data-base system for northern Midwest regional aquifer-system analysis
A.L. Kontis, Richard J. Mandle
1980, Water-Resources Investigations Report 80-104
The U.S. Geological Survey is conducting a study of the Cambrian and Ordovician aquifer system of the northern Midwest as part of a national series of Regional Aquifer-Systems Analysis (RASA). An integral part of this study will be a simulation of the ground-water flow regime using the Geological Survey's three-dimensional...
Hydrology and model study of the proposed Prosperity Reservoir, Center Creek Basin, southwestern Missouri
Edward Joseph Harvey, Leo F. Emmett
1980, Water-Resources Investigations Report 80-7
A dam and reservoir have been proposed for construction on Center Creek, Jasper County, in southwestern Missouri. Ground-water levels in the hills adjacent to the reservoir will rise when the impoundment is completed. One of the problems is that the proposed site of Prosperity Reservoir is a few miles upstream...
