Using channel geometry to estimate flood flow at ungaged sites in Idaho
W. A. Harenberg
1980, Water-Resources Investigations Report 80-32
Measurements at bankfull stage were made at 136 sites to determine whether predictions of flood discharges using channel-geometry characteristics are as good as or better than predictions using basin characteristics. These measurements are used to determine the variables of bankfull width, area, depth, and velocity. These variables are combined with...
Hydrology of the Chicod Creek basin, North Carolina, prior to channel improvements
Clyde E. Simmons, Mary C. Aldridge
1980, Open-File Report 80-680
Extensive modification and excavation of stream channels in the 6-square mile Chicod Creek basin began in mid-1979 to reduce flooding and improve stream runoff conditions. The effects of channel improvements on this Coastal Pain basin 's hydrology will be determined from data collected prior to, during, and for several years...
A preliminary report of the geohydrology of the Mississippi salt-dome basin
C. A. Spiers, L. A. Gandl
1980, Open-File Report 80-595
The U.S. Department of Energy is investigating the suitability of salt domes in the Mississippi salt-dome basin as repositories for storing radioactive wastes. The Department of Energy has requested that the U.S. Geological Survey describe the groundwater hydrology of the Mississippi salt-dome basin, giving special attention to direction and rate...
Ground-water appraisal of the Fishkill-Beacon area, Dutchess County, New York
Deborah S. Snavely
1980, Open-File Report 80-437
The most productive aquifers in the Fishkill-Beacon area, Dutchess County, N.Y., are the sand and gravel beds in the northeast corner of the area and along the valleys of Fishkill and Clove Creeks. The average yield of these aquifers to wells is 190 gal/min (gallons per minute). The most productive...
Distribution of trace elements in bottom sediment of the northern Bering Sea
Bradley R. Larsen, C. Hans Nelson, Chris Heropoulos, Jeffrey J. Patry
1980, Open-File Report 80-399-A
2-dimensional contour and 3-dimensional value-surface maps of semi-quantitative emission spectographic analyses for over 50 elements in surface sediment from 180 sampling stations are presented. For purposes of discussion, certain of these elements have been grouped into the following categories: petroleum indicators, heavy metals, potentially toxic elements, chemically sensitive elements, major...
Evaluation of peak-flow data network of small streams in Missouri
Leland D. Hauth
1980, Water-Resources Investigations Report 80-87
Standard regression models were used as a tool to evaluate the transferability of streamflow characteristics for the small-streams network in Missouri. Station records were divided into segments and tested for adequacy of record length and sample size for two physiographic regions. The standard error of estimate for each calibrated regression...
Analyses of water and dredged material from selected southern Louisiana waterways and selected areas in the Gulf of Mexico, 1976-78
Geraldine R. Stallworth, Helen F. Jordan
1980, Open-File Report 80-694
The U.S. Geological Survey was requested by the U.S. Army Corps of Engineers to provide water-quality data to evaluate the potential environmental effects of (1) dredging activities in selected navigable waterways of southern Louisiana and (2) the disposal of dredged material at selected areas in the Gulf of Mexico. Areas...
Finite-difference model to simulate the areal flow of saltwater and fresh water separated by an interface
James W. Mercer, S. P. Larson, Charles R. Faust
1980, Open-File Report 80-407
Model documentation is presented for a two-dimensional (areal) model capable of simulating ground-water flow of salt water and fresh water separated by an interface. The partial differential equations are integrated over the thicknesses of fresh water and salt water resulting in two equations describing the flow characteristics in the areal...
