1981, Open-File Report 81-542
A requirement of Public Law 95-87, the Surface Mining Control and Reclamation Act of 1977, is the understanding of the hydrology in actual and proposed surface-mined areas. Surface-water data for small specific-sites and for larger areas such as adjacent and general areas are needed also to satisfy the hydrologic requirements...

Robert E. Davis, Scott C. Christenson
1981, Open-File Report 81-483
A quantitative description of the hydrologic system in alluvium and terrace deposits along the Beaver-North Canadian River in northwestern Oklahoma is needed as an aid for planning and management of the aquifer. A two-dimensional finite-difference model was used to describe the aquifer and to predict the effects of future ground-water...

Supplement to predictive modeling of effects of the planned Kindred Lake on ground-water levels and discharge, southeastern North Dakota
C. A. Armstrong
1981, Open-File Report 81-646
A digital model was used to describe a ground-water system in glacial deltaic deposits near Kindred, N.D., and to predict the effects on ground-water levels of a planned lake at the 950-, 960-, 970-, 984-, and 995-foot stages. Model analysis indicates that only the area within a radius of about...
Hydrology of Area 7, Eastern Coal Province, Ohio
Morris J. Engelke Jr., D.K. Roth, and others
1981, Open-File Report 81-815
The U.S. Geological Survey established 24 study areas in Eastern Appalachian Coal Province to appraise the hydrology and water resources from Alabama to Pennsylvania. Chemical, physical, biological, and streamflow data were collected from 138 synoptic sites in Area 7, eastern Ohio. The data are evaluated and presented in this report....
Digital-model simulation of the Toppenish alluvial aquifer, Yakima Indian Reservation, Washington
E.L. Bolke, James A. Skrivan
1981, Open-File Report 81-425
Increasing demands for irrigating additional lands and proposals to divert water from the Yakima River by water users downstream from the Yakima Indian Reservation have made an accounting of water availability important for present-day water management in the Toppenish Creek basin. A digital model was constructed and calibrated for the...
