Ground-water quality in the Santa Rita, Buellton, and Los Olivos hydrologic subareas of the Santa Ynez River basin, Santa Barbara County, California
S. N. Hamlin
1985, Water-Resources Investigations Report 84-4131
Groundwater quality in the upper Santa Ynez River Valley in Santa Barbara County has degraded due to both natural and anthropogenic causes. The semiarid climate and uneven distribution of rainfall has limited freshwater recharge and caused salt buildup in water supplies. Tertiary rocks supply mineralized water. Agricultural activities (irrigation return...
Evaluation of the Mission, Santee, and Tijuana hydrologic subareas for reclaimed-water use, San Diego County, California
J. A. Izbicki
1985, Water-Resources Investigations Report 85-4032
A study was made to determine the suitability of three small hydrologic subareas in San Diego County, California, for reuse of treated municipal wastewater (reclaimed water). Groundwater quality has been impacted by agricultural water use, changes in natural recharge patterns, seawater intrusion, and groundwater movement from surrounding marine sediments. Groundwater...

1985, Water-Resources Investigations Report 85-4086
Regression relations were determined for estimating mean annual discharge, mean monthly discharge, minimum and maximum 7-day discharge, flow duration series, and peak discharge for natural streams in western Colorado. Multiple regression analyses were used to determine the best predictive relations for each of the streamflow characteristic; separate relations were developed...
Hydrology of Fritchie Marsh, coastal Louisiana
E. L. Kuniansky
1985, Water-Resources Investigations Report 84-4324
Fritchie Marsh, near Slidell, Louisiana, is being considered as a disposal site for sewage effluent. A two-dimensional, finite element, surface water modeling systems was used to solve the shallow water equations for flow. Factors affecting flow patterns are channel locations, inlets, outlets, islands, marsh vegetation, marsh geometry, stage of the...
Management of ground water and evolving hydrogeologic studies in New Jersey : a heavily urbanized and industrialized state in the northeastern United States
P. Patrick Leahy
1985, Water-Resources Investigations Report 85-4277
New Jersey is the most densely populated and one of the most industrialized states in the United States. An abundance of freshwater and proximity to major northeastern metropolitan centers has facilitated this development. Pumpage of freshwater from all aquifers in the State in 1980 was 730 million gallons per day...
Summary of northern Atlantic Coastal Plain hydrology and its relation to disposal of high-level radioactive waste in buried crystalline rock – A preliminary appraisal
O. B. Lloyd, J. D. Larson, R. W. Davis
1985, Water-Resources Investigations Report 85-4146
Interpretation of available hydrologic data suggests that some areas beneath the Coastal Plain in the States of Delaware, Maryland, New Jersey, North Carolina, and Virginia might have some potential for the disposal of nuclear waste in crystalline rock that is buried beneath the Coastal Plain sediments. The areas of major...

This report documents the results of a study of the cost-effectiveness of the stream-gaging program in North Carolina. Data uses and funding sources are identified for the 146 gaging stations currently operated in North Carolina with a budget of $777,600 (1984). As a result of the study, eleven stations are...
Potential effects of surface coal mining on the hydrology of the Horse Creek area, Sheridan and Moorhead coal fields, southeastern Montana
N. E. McClymonds
1985, Water-Resources Investigations Report 84-4239
The Horse Creek area of the Sheridan and Moorhead coal fields, 16 miles east of the Decker Coal Mines near the Tongue River, contains large reserves of Federally owned coal that have been identified for potential lease sale. A hydrologic study was conducted in the area to describe existing hydrologic...
Evaluation of the effects of coal-mine reclamation on water quality in Big Four Hollow near Lake Hope, southeastern Ohio
V.E. Nichols
1985, Water-Resources Investigations Report 85-4197
A subsurface clay dike and mine-entrance hydraulic seals were constructed from July 1979 through May 1980 by the Ohio Department if Natural Resources, Division of Reclamation to reduce acidic mine drainage from abandoned drift-mine complex 88 into Big Four Hollow Creek. Big Four Hollow Creek flows into Sandy Run--the major...
Summary of hydrologic information for the Denver coal region, Colorado
J. M. Norris, S. G. Robson, R. S. Parker
1985, Water-Resources Investigations Report 84-4337
A literature review of available hydrologic information for the Denver coal region is presented. Where little information is available, data from the U.S. Geological Survey 's WATSTORE data base are summarized. The information is divided into three categories: surface water, surface water quality, and groundwater. Data generally are lacking on...
Magnitude and frequency of floods in Alabama
D.A. Olin
1985, Water-Resources Investigations Report 84-4191
Methods are presented to estimate flood magnitude for selected recurrence intervals for urban and rural streams with drainage areas from 1 to 22,000 square miles. Seven hydrologic areas were delineated and regression equations were developed for six areas. Hydrologic data could not be regionalized for the seventh area. Drainage area...
Estimation of selected flow and water-quality characteristics of Alaskan streams
Bruce Parks, R. J. Madison
1985, Water-Resources Investigations Report 84-4247
Although hydrologic data are either sparse or nonexistent for large areas of Alaska, the drainage area, area of lakes, glacier and forest cover, and average precipitation in a hydrologic basin of interest can be measured or estimated from existing maps. Application of multiple linear regression techniques indicates that statistically significant...
Hydrology and its effects on distribution of vegetation in Congaree Swamp National Monument, South Carolina
Glenn G. Patterson, Gary K. Speiran, Benjamin H. Whetstone
1985, Water-Resources Investigations Report 85-4256
Congaree Swamp National Monument preserves a large stand of old-growth southern bottomland hardwood forest on the flood plain of the Congaree River. The distribution of vegetation types in the Monument is controlled by duration of saturated soil conditions during the growing season, which is related to duration of inundation by...
