Hydrologic data for urban studies in the Houston metropolitan area, Texas, 1984
Fred Liscum, J.P. Bruchmiller, D. W. Brown, E.M. Paul
1987, Open-File Report 86-608
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in the Austin and Houston areas, and have been completed in the Dallas-Fort Worth and San Antonio areas. The U.S. Geological Survey, in cooperation with the city of Houston, began...
The effects of boundary conditions on the steady-state response of three hypothetical ground-water systems; results and implications of numerical experiments
O. Lehn Franke, Thomas E. Reilly
1987, Water Supply Paper 2315
The most critical and difficult aspect of defining a groundwater system or problem for conceptual analysis or numerical simulation is the selection of boundary conditions . This report demonstrates the effects of different boundary conditions on the steady-state response of otherwise similar ground-water systems to a pumping stress. Three series...
Relation of sediment and nutrient loads to watershed characteristics and land use in the Otisco Lake basin, Onondaga County, New York
J.E. Paschal, D. A. Sherwood
1987, Water-Resources Investigations Report 86-4026
Otisco Lake, the smallest and easternmost of New York State 's Finger Lakes, is the source of water supply for several villages in Onondaga County. In recent years, turbidity and algal blooms have periodically impaired the lake 's use for both water supply and recreation. Principal land uses within the...
Selected water-quality data for the Burley irrigation district, south-central Idaho, March-April, 1987
H.W. Young, D. J. Parliman, M.L. Jones
1987, Open-File Report 87-240
This map report presents selected March-April 1987, water quality data, principally dissolved nitrite plus nitrate as nitrogen, and depth-to-water measurements for 118 wells in the Burley Irrigation District, south-central Idaho. Nitrogen concentrations ranged from 0.37 to 30 mg/L; the median concentration was 8.0 mg/L. Nitrogen concentrations in 19 wells equaled...
Geology of the Ar Rahail ancient gold mine, Kingdom of Saudi Arabia
Willis H. White, Rashid M. Samater, Jeff L. Doebrich
1987, Open-File Report 88-26
The Ar Rahail ancient gold mine is a collection of ancient workings in metasedimentary rocks of the Murdama Group adjacent to, and above the flanks of the Rahail stock. Injection of mafic dikes of regional origin was followed by emplacement of the Rahail stock, which consisted of early dikes of...

1987, Water Data Report MO-86-1
Water resources data for the 1986 year for Missouri consist of records of stage, discharge, and water quality of lakes and reservoirs; contains records for water discharge at 107 gaging stations; stage and contents at 10 lakes and reservoirs; water quality at 67 sampling stations (including 2 lakes); and data...
Water resources data for Oregon, water year 1985. Volume 1: Eastern Oregon
C.W. Alexander, R. L. Moffatt, P. R. Boucher, M.L. Smith
1987, Water Data Report OR-85-1
Water Resources Data for the 1985 water year for Oregon consist of records of stage, discharge, and water quality of streams; and stage, contents, and water quality of lakes and reservoirs. This report, in two volumes , contains discharge records for 259 gaging stations; stage only records for 10 gaging...
Geochemistry and preliminary assessment of resource potential for postorogenic granites of the southwestern Arabian Shield, Kingdom of Saudi Arabia
J. S. Stuckless, George VanTrump Jr., C. A. Bush, R. B. Vaughn, A.J. Bartel
1987, Open-File Report 87-509
Geochemical data for samples from 55 postorogenic plutons of the southwestern Arabian Shield show that these granitoids are generally less evolved than similar granitoids of the eastern Arabian Shield. Radioelement contents are low to normal relative to typical granitic rocks and uranium contents are distinctly low relative to rocks of...
