Stratigraphy of an archeological site, Ocmulgee flood plain, Macon, Georgia
Oliver J. Cosner
1973, Water-Resources Investigations Report 73-54
Archeological excavations on the Ocmulgee River flood plain at Ocmulgee National Monument revealed eight sedimentary units of Holocene age. Types of deposits found are natural levee, oberbank deposit, and a probable point bar. Since the 18th century, locally more than 10 feet of sediment has been deposited. These modern sediments...
Effects of Urbanization on Floods in the Houston, Texas Metropolitan Area
Steven L. Johnson, Douglas M. Sayre
1973, Water-Resources Investigations Report 73-3
Rainfall and runoff data from drainage basins in the Houston metropolitan area and a 60-year rainfall record for the National Weather Service station, Houston-City, were used to simulate 60 annual flood peaks at 26 sites. Selected frequency characteristics, based on these simulated annual peaks, are related to drainage area and...
An evaluation of water-quality data obtained at four streamflow daily-record stations in Idaho
Kenneth L. Dyer
1973, Water-Resources Investigations Report 73-30
Chemical data for four stream-gaging stations in Idaho, each having 6 to 22 years of available records, were analyzed to determine functional relations between concentrations of the major inorganic constituents, specific conductance, and stream discharge. Three of the four stations had sufficient available record for assessing changes in constituent relations...
Ground-water hydrology of northern Napa Valley, California
Robert E. Faye
1973, Water-Resources Investigations Report 73-13
The alluvium of northern Napa Valley is the principal aquifer of the area and is capable of yielding as much as 3,000 gallons per minute to wells. Generally the larger-yielding wells are along the Napa River where the alluvium is thickest and most permeable. Recharge to the alluvium is chiefly...
Electric-analog simulation network of unconsolidated aquifers in the upper Wabash River basin, Indiana
James E. Heisel
1973, Water-Resources Investigations Report 73-29
The ground-water budget of the unconsolidated deposits in the upper Wabash River basin was modeled. An electrical-simulation network was used to determine an integrated storage coefficient of 0.003 for the basin. Two practical problems were investigated: a municipal pumping problem and the change in flow regime due to the addition...
A survey of the water resources of St. Thomas, Virgin Islands
D.G. Jordon, O. J. Cosner
1973, Open-File Report 72-201
St. Thomas, with an area of 32 square miles, is the second largest of the Virgin Islands of the United States. The island is mountainous, and slopes commonly exceed 35 degrees along a central ridge 800 to 1,200 feet high running the length of the island. The general appearance is...
Preliminary investigation of land subsidence in the Sacramento Valley, California
B. E. Lofgren, R. L. Ireland
1973, Open-File Report 74-1064
Although a number of agencies have made leveling surveys in Sacramento Valley and a valleywide network of first- and second-order control exists, few areas have sufficient control for determining whether land subsidence has occurred and if so, how much, within the time span of vertical control. Available data suggest that...
Measurement of lateral erosion at proposed river crossing sites of the Alaskan pipeline
James Brice
1973, Open-File Report 73-31
This study of lateral erosion rates by comparison of aerial photographs was undertaken at the request of D. M. Culbertson, hydraulic engineer, U.S. Geological Survey, Menlo Park, Calif., and preparatory work in Alaska (during June 1-18, 1971) was done with the cooperation of Harry Hulsing, district chief, Alaska District. Examination...
