Factors affecting the recognition of faults exposed in exploratory trenches
Manuel G. Bonilla, James J. Lienkaemper
1991, Bulletin 1947
Trenching-a widely used method for evaluating fault activity-has limitations that can mislead investigators. Some segments of fault strands in trench walls may not be visible, and this nonvisibility can lead to incorrect interpretations of time of most recent displacement and recurrence intervals on a fault. We examined the logs of...
Hydrogeology and simulation of ground-water flow in the Rochester area, southeastern Minnesota, 1987-88
G. N. Delin
1991, Water-Resources Investigations Report 90-4081
Ground-water flow in the St. Peter-Prairie du Chien-Jordan aquifer was studied in a 700 square-mile area surrounding Rochester, Minnesota. The aquifer consisting of sandstone, limestone, and dolomite is locally confined by the Decorah-Platteville-Glenwood sequence of shales and limestones. Regional flow in the aquifer is from a ground-water divide on the...
Simulation of effects of ground-water development on water-levels in glacial-drift aquifers in the Brooten-Belgrade area, west-central Minnesota
G. N. Delin
1991, Water-Resources Investigations Report 88-4193
Ground-water flow in the confined- and unconfined-drift aquifers in the Brooten-Belgrade area of west-central Minnesota was simulated with a three-dimensional finite-difference ground-water-flow model. Model results indicate that about 96 percent of the total inflow to the modeled area is from precipitation. Discounting evapotranspiration, 63 percent of the total outflow is...
Review of water demand and water utilization studies for the Provo River drainage basin, and review of a study of the effects of the proposed Jordanelle Reservoir on seepage to underground mines, Bonneville unit of the central Utah project
K.M. Waddell, G. W. Freethey, D. D. Susong, G. E. Pyper
1991, Open-File Report 91-514
Problem: Questions have been raised concerning the adequacy of available water to fulfill the needs of storage, exchanges, diversions, and instream flows, pursuant to existing water rights in the Provo River drainage basin part of the Bonneville Unit. Also, concern has been expressed about the potential for seepage of water from...
Water-resources activities, North Dakota District, fiscal year 1990
1991, Open-File Report 91-188
The mission of the U.S. Geological Survey, Water Resources Division, is to provide the hydrologic information and understanding needed for the optimum utilization and management of the Nation's water resources for the overall benefit of the people of the United States. This report describes waterresources activities of the Water Resources...
Estimated use of water in North Dakota in 1985 and trends during 1960-85
Edwin A. Wesolowski
1991, Water-Resources Investigations Report 89-4003
Estimates of water use in North Dakota have been compiled by the U.S. Geological Survey every 5 years since 1950.  These estimates have been published in national summaries of water use (MacKichan, 1951, 1957; MacKichan and Kammerer, 1961; Murray, 1968; Murrary and Reeves, 1972, 1977; and Solley and others, 1983,...
