1973, Open-File Report 73-191
The U.S. Geological Survey is conducting a geological and geophysical study of the northeastern United States Outer Continental Shelf and the adjacent slope from Georges Bank to Cape Hatteras. The study also includes the adjacent Coastal Plain because it is a more accessible extension of the shelf. The total study...
Water resources outlook for the Minneapolis-Saint Paul Metropolitan Area, Minnesota
R.F. Norvitch, T.G. Ross, Alex Brietkrietz
1973, Open-File Report 73-203
The water resources were studied within an area whose natural ground-water flow is largely towards the center of the metropolitan area. This area coincides with the extent of the Hinckley Sandstone aquifer. Thus, the general geohydrology of the area bounded by the extent of the Hinckley Sandstone (about 6,000 square...

Geohydrology and artificial-recharge potential of the Irvine area, Orange County, California
John A. Singer
1973, Open-File Report 73-264
The Irvine area is in hydraulic continuity with the rest of the coastal plain in Orange County. Factors that distinguish the aquifer section of the Irvine area from that in other parts of the coastal plain are a low permeability, a high clay and silt content, and a thin alluvial...

A plan for study of water resources in the Platte River basin, Nebraska: with special emphasis on the stream-aquifer relations
C.F. Keech, J.E. Moore, P. A. Emery
1973, Open-File Report 73-139
A "Level B" study is being made of the Platte River basin in Nebraska. The basin (approximately 40,800 square miles) extends the full length of the State, a distance of nearly 470 miles. The study is a Federal and State interagency effort to formulate a comprehensive plan for the conservation,...
Mercury in the Carson and Truckee River basins of Nevada
A. S. Van Denburgh
1973, Open-File Report 73-352
Upstream from major pre-1900 ore milling in the Carson and Truckee River basins, "background" concentrations of total mercury in the upper 1 to 3 inches of sand- to clay-sized stream-bottom sediment are less than 0.1 ug/g (microgram per gram). Downstream, measured concentrations were as much as 200 times the background...

Velocity and depth measurements for use in computation of reaeration coefficients
John S. Zogorski, Peter W. Anderson, Owen O. Williams
1973, Open-File Report 73-369
Empirical computation of reaeration coefficients generally requires knowledge of mean velocity and mean depth of a stream. A practical method for obtaining this knowledge is described herein. The method involves time-of-travel, streamflow, and cross-sectional measurements, the development of discharge-velocity curves, streamflow profiles, and the computation of cross-sectional areas. Values for...
