A two-dimensional finite-difference digital model was constructed to simulate effects of proposed pumping and recharge schemes on water levels in the Hollister Valley ground-water basin. Pumping rates in the valley are expected to increase from 24,000 acre-feet per year in 1968 to an ultimate rate of 38,500 acre-feet per year....
Flood profiles along the Cedar River, King County, Washington
O.C. Hettick
1979, Water-Resources Investigations Report 78-84
Flood profiles on the Cedar River, King County, Wash., were developed from 21.1 to 33.65 miles upstream from the mouth for the flood of December 3-4, 1975, and for a 100-year flood. Estimated water-surface elevations during a 100-year flood indicate virtually all the flow would be contained in the river...

Miguel A. Lopez, Eloy Colon-Dieppa, Ernest D. Cobb
1979, Water-Resources Investigations Report 78-141
Annual-peak discharge records at 50 sites in Puerto Rico with five or more years of record were used to determine individual site log-Pearson type III frequency curves. The frequency curve values for 2-, 10-, 25-, 50-, and 100-year recurrence intervals at 37 sites with 10 or more years of record...
Saltwater-barrier line in Florida: Concepts, considerations, and site examples
Jerry L. Hughes
1979, Water-Resources Investigations Report 79-75
Construction of canals and enlargement of streams in Florida has been mostly to alleviate impact of floods and to drain wetlands for development. Land drainage and heavy pumpage from coastal water-table aquifers has degraded potable ground and surface water with saltwater. Control of saltwater intrusion is possible through implementation of...

A two-dimensional digital-computer flow model was developed to simulate the Farrington aquifer in the northern part of the Coastal Plain of New Jersey. The area of detailed study includes approximately 500 square miles in Middlesex and Monmouth Couties where the aquifer provides a large part of the municipal and industrial...
Chemical, physical, and radiological quality of selected public water supplies in Florida, November 1977-February 1978
G. A. Irwin, Robert W. Hull
1979, Water-Resources Investigations Report 79-50
Virtually all treated public water supplies sampled in Florida meet the National Interim Primary and Proposed Secondary Drinking Water Regulations. These findings are based on a water-quality reconnaissance of 129 treated public supplies throughout the State during the period November 1977 through February 1978. While primary drinking water regulation exceedences...
Physical, chemical, and biological characteristics of Ross Lake, Snohomish County, Washington
N. P. Dion
1979, Water-Resources Investigations Report 78-44
A study of the physical, chemical, and biological characteristics of Ross Lake in 1975 showed that the lake has no well-defined surface-water inflow and that thermal stratification is well established in summer. The water is of a calcium bicarbonate type, which is typical of lakes in western Washington.Biological productivity in...

1979, Water-Resources Investigations Report 79-46
Hydrology-related problems associated with North Carolina's major estuaries and sounds include contamination of some estuaries with municipal and industrial wastes and drainage from adjacent intensively-farmed areas, and nuisance-level algal blooms. In addition, there is excessive shoaling in some navigation channels, saltwater intrusion into usually fresh estuarine reaches, too-high or too-low...
Documentation of a finite-element two-layer model for simulation of ground-water flow

John M. Klein, Wesley L. Bradford
1979, Water-Resources Investigations Report 79-60
Nitrogen in the unsaturated soil zone in the vicinity of Redlands in San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans have been made to recharge the aquifer with imported surface water. If this occurs, the rising water table will intercept soluble...

B. W. Drost
1979, Water-Resources Investigations Report 79-12
The Swinomish Indian Reservation occupies 17 mi2on Fidalgo Island, northwestern Washington. Six square miles are underlain by mudflats or low-lying alluvial deposits, and are not part of the study area. An appraisal of the water resources of the reservation was made because the Swinomish Tribal Community expects rapid economic and...

John S. Havens, D. W. Wilkins
1979, Water-Resources Investigations Report 80-4
Upward-leaking brine, from a confined aquifer at the base of the Rustler Formation, mixes with fresher water in a shallow aquifer, resulting in discharge to the Pecos River in southern Eddy County, New Mexico, of about 0.5 cubic feet per second of saturated brine. Pumping brine from the aquifer at...
Flood characteristics of Alaskan streams
