A gravity study of the northern part of the Arctic National Wildlife Range, Alaska
B. A. Kososki, H. N. Reiser, C. D. Cavit, R. L. Detterman
1978, Bulletin 1440
Interpretation of all publicly available onshore gravity data provides a basis for outlining regional elements of the basement and overlying structure in the northern part of the Arctic National Wildlife Range. Major post-Carboniferous sedimentary basins whose centers lie offshore on the Beaufort Shelf extend onshore in the northern part of...
A rainfall-runoff modeling procedure for improving estimates of T-year (annual) floods for small drainage basins
Robert W. Lichty, Fred Liscum
1978, Water-Resources Investigations Report 78-7
Maps depicting the influence of a climatic factor, C, on the magnitude of synthetic T-year (annual) floods were prepared for a large portion of the eastern United States. The climatic factors were developed by regression analysis of flood data using a parametric rainfall-runoff model and long-term rainfall records. Map estimates...
Availability and quality of water from shallow aquifers in Duval County, Florida
Lawson V. Causey, G. G. Phelps
1978, Water-Resources Investigations Report 78-92
The shallow-aquifer system in Duval County, Fla., overlies the Florida aquifer and is composed chiefly of sand, clay, sandy clay, and limestone. Thickness of the system ranges from about 300 to 600 feet. The upper 150 feet of deposits, consisting of the water-table and shallow-rock zones, are the most dependable...
Computer modeling of ground-water availability in the Pootatuck River Valley, Newtown, Connecticut
F.P. Haeni, Elinor H. Handman
1978, Water-Resources Investigations Report 78-77
A hydrologic analysis of the stratified drift in Newtown, Conn., based on available data, test drilling, seismic refraction profiling, and the stream-aquifer connection was performed using a digital computer model. Simulated pumping indicates that a total of 4.0 million gallons of water per day (Mgal/d) can be withdrawn from the...
An analysis of stream temperatures, Green River Basin, Wyoming
H. W. Lowham
1978, Water-Resources Investigations Report 78-13
A method for estimating temperatures of streams in the Green River basin, Wyoming, utilizes a regional model for estimating mean daily temperatures of streams at unmeasured sites. The regional model was developed by describing annual temperature patterns at 43 measured sites and by applying the harmonic function T = M...
Progress report on hydrologic investigations of small drainage areas in New Hampshire: preliminary relations for estimating peak discharges on rural, unregulated streams
Denis R. LeBlanc
1978, Water-Resources Investigations Report 78-47
The magnitude and frequency of floods on rural, unregulated streams in New Hampshire with drainage areas between 0.27 and 622 square miles may be estimated from drainage area, main-channel slope, and a precipitation intensity index. Based on multiple-regression analyses of data from 59 gaged sites in New Hampshire and adjacent...
Dissolved-solids budget of Lake Okeechobee, Florida, October 1964 to September 1974
David V. Maddy
1978, Water-Resources Investigations Report 77-97
Lake Okeechobee is a major surface-water storage facility for south Florida. A dissolved-solids budget for Lake Okeechobee was computed for Oct. 1964 to Sept. 1974, a 10-year budget period. Calculations were based on records of daily discharge, daily specific conductance measurements, and regression equations relating dissolved-solids concentrations and specific conductance....
