Status of surface-water modeling in the U.S. Geological Survey
Marshall E. Jennings, Nobuhiro Yotsukura
1979, Circular 809
The U.S. Geological Survey is active in the development and use of models for the analysis of various types of surface-water problems. Types of problems for which models have been, or are being developed, include categories such as the following: (1)specialized hydraulics, (2)flow routing in streams, estuaries, lakes, and reservoirs,...
Water quality in the proposed Prosperity Reservoir area, Center Creek Basin, Missouri
James H. Barks, Wayne R. Berkas
1979, Water-Resources Investigations Report 79-22
Water in Center Creek basin, Mo., upstream from the proposed Prosperity Reservoir damsite is a calcium bicarbonate type that is moderately mineralized, hard, and slightly alkaline. Ammonia and organic nitrogen, phosphorus, total organic carbon, chemical oxygen demand, and bacteria increased considerably during storm runoff, probably due to livestock wastes. Nitrogen...

Mesozoic stratigraphy: the key to tectonic analysis of southern and central Alaska
David Lawrence Jones, Norman J. Silberling
1979, Open-File Report 79-1200
Southern and central Alaska constitutes an enormous tectonic mosaic composed of separate structural blocks and fragments that accreted to North America during Mesozoic and early Cenozoic time. Some of these blocks are far traveled, as shown by paleomagnetic and paleontologic studies. More than 25 discrete tectonostratigraphic terranes now are known,...
Analyses of surficial deposits, central Brooks Range, Alaska
Thomas D. Hamilton, James H. Trexler, James McCalpin
1979, Open-File Report 79-228
Seventy-nine sediment samples from the central Brooks Range were analyzed for grain-size distribution, shape and composition of grains, and other physical properties. Four statistical measures (sorting, mean diameter, skewness, and kurtosis) were then computed for the sand-to-clay size fraction of all samples.Fan sediments resemble the other alluvial-gravel deposits in consisting...
Modeling highly transient flow, mass, and heat transport in the Chattahoochee River near Atlanta, Georgia

1979, Open-File Report 79-270
A coupled flow-temperature model has been developed and verified for a 27.9-km reach of the Chattahoochee River between Buford Dam and Norcross, Ga. Flow in this reach of the Chattahoochee is continuous but highly regulated by Buford Dam, a flood-control and hydroelectric facility located near Buford, Ga. Calibration and verification...
