Estimation of the recharge area contributing water to a pumped well in a glacial-drift, river-valley aquifer
D. J. Morrissey
1987, Open-File Report 86-543
The highly permeable, unconfined, glacial drift aquifers that occupy most New England river valleys constitute the principal source of drinking water for many communities that obtain part or all of their public water supply from groundwater. Analytical , two-dimensional numerical and three-dimensional numerical models were used to delineate contributing areas...

J. A. Moreland, Hugh Liebscher, W. A. Van Voast, R.D. Feltis
1987, Open-File Report 87-28
The area of the proposed Cabin Creek coal mine was studied to obtain information needed to respond to questions posed by the International Joint Commission advisers concerning water resources near the international border. Specific interest focused on determining the extent and character of surficial material in the Flathead River valley,...
Annual yield and selected hydrologic data for the Arkansas River Basin Compact, Arkansas-Oklahoma, 1986 water year
M. A. Moore, T.E. Lamb, S. P. Blumer
1987, Open-File Report 87-203
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, minimum, and mean discharges are shown...
Interpretation of detailed aerial gamma-ray survey, Jabal Ashirah area, southeastern Arabian Shield, Kingdom of Saudi Arabia
J. S. Duval
1987, Open-File Report 87-599
A detailed aerial gamma-ray spectrometric survey of the Jabal Ashirah area in the southeastern Arabian Shield has been analyzed using computer-classification algorithms. The analysis resulted in maps that show radiometric map units and gamma-ray anomalies indicating the presence of possible concentrations of potassium and uranium. The radiometric-unit map was interpreted...
