Water resources data, Maine, water year 1986
W.P. Bartlett Jr., W.B. Higgins, W.J. Nichols Jr.
1988, Water Data Report ME-86-1
Water resources data for the 1986 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains discharge records for 48 gaging stations; stage only for 2...
Cumulative potential hydrologic impacts of surface coal mining in the eastern Powder River structural basin, northeastern Wyoming
L.J. Martin, D. L. Naftz, H. W. Lowham, J.G. Rankl
1988, Water-Resources Investigations Report 88-4046
There are 16 existing and six proposed surface coal mines in the eastern Powder River structural basin of northeastern Wyoming. Coal mining companies predict water level declines of 5 ft or more in the Wasatch aquifer to extend form about 1,000 to about 2,000 ft beyond the mine pits. The...
Geologic and hydrologic investigations of a potential nuclear waste disposal site at Yucca Mountain, southern Nevada
Michael D. Carr, James C. Yount, editor(s)
1988, Bulletin 1790
Crustal velocity sections based on two seismic-refraction profiles are presented for the area west of Yucca Mountain, Nye County, Nevada. The Crater Flat profile is interpreted in terms of six velocity layers ranging from 1.5 to 6.1 km/s. Interpretation of the Beatty profile reveals an escarpment near the northeast edge...
Simulation of flow in the Edwards Aquifer, San Antonio region, Texas, and refinement of storage and flow concepts
Robert W. Maclay, Larry F. Land
1988, Water Supply Paper 2336-A
The Edwards aquifer is a complexly faulted, carbonate aquifer lying within the Balcones fault zone of south-central Texas. The aquifer consists of thin- to massive-bedded limestone and dolomite, most of which is in the form of mudstones and wackestones. Well-developed secondary porosity has formed in association with former erosional surfaces...
A computer program incorporating Pitzer's equations for calculation of geochemical reactions in brines
Niel Plummer, D.L. Parkhurst, G.W. Fleming, S.A. Dunkle
1988, Water-Resources Investigations Report 88-4153
The program named PHRQPITZ is a computer code capable of making geochemical calculations in brines and other electrolyte solutions to high concentrations using the Pitzer virial-coefficient approach for activity-coefficient corrections. Reaction-modeling capabilities include calculation of (1) aqueous speciation and mineral-saturation index, (2) mineral solubility, (3) mixing and titration of aqueous...
Alternative sources of large seasonal ground-water supplies in the headwaters of the Susquehanna River basin, New York
A. D. Randall, D. S. Snavely, T.P. Holecek, R.M. Waller
1988, Water-Resources Investigations Report 85-4127
The northern divide of the Susquehanna River basin crosses 29 broad valleys that contain thick glacial deposits but are drained only by small headwater streams. Much groundwater could be withdrawn from sand and gravel deposits in these valleys with little immediate effect on streamflow. A digital model of the headwater...
