Geohydrology, Geochemistry, and Ground-Water Simulation-Optimization of the Central and West Coast Basins, Los Angeles County, California
Historical ground-water development of the Central and West Coast Basins in Los Angeles County, California through the first half of the 20th century caused large water-level declines and induced seawater intrusion. Because of this, the basins were adjudicated and numerous ground-water management activities were implemented, including increased water spreading, construction of injection barriers,

Water quality in the Kanawha-New River basin: West Virginia, Virginia, and North Carolina, 1996-98
This report summarizes major findings about water quality in the Kanawha-New River basin that emerged from an assessment conducted between 1996 and 1998 by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program. Water quality is discussed in terms of local and regional issues and compared to conditions found in all 36 NAWQA study areas assessed to date. Findings also a

Evaluation of surface-water/ground-water interactions in the Santa Clara River Valley, Ventura County, California
The interactions of surface water and ground water along the Santa Clara River in Ventura County, California, were evaluated by analyzing river-discharge and water-quality data and geohydrologic information collected by the U.S. Geological Survey between 1993 and 1995 for the Piru, Fillmore, and Santa Paula subbasins. Measurements of discharge and water quality were made at multiple locations alon

Numerical model of a tracer test on the Santa Clara River, Ventura County, California
To better understand the flow processes, solute-transport processes, and ground-water/surface-water interactions on the Santa Clara River in Ventura County, California, a 24-hour fluorescent-dye tracer study was performed under steady-state flow conditions on a 45-km reach of the river. The study reach includes perennial (uppermost and lowermost) subreaches and ephemeral subreaches of the lower Pi

Statistical analysis and mathematical modeling of a tracer test on the Santa Clara River, Ventura County, California
To better understand flow processes, solute-transport processes, and ground-water/surface-water interactions on the Santa Clara River in Ventura County, California, a 24-hour fluorescent-dye tracer study was performed under steady-state flow conditions on a 28-mile reach of the river.
The study reach includes perennial (uppermost and lowermost) subreaches and ephemeral subreaches of the lower Pir

Water-quality trends in the Santa Ana River at MWD Crossing and below Prado Dam, Riverside County, California
The Santa Ana River, located in an extensively urbanized basin, drains about 2,670 square miles near Los Angeles, California. Almost all flow in the river, about 200,000 acre-feet annually, is diverted to ponds where it infiltrates and recharges underlying aquifers. About 2 million people are dependent on these aquifers for water supply. In recent years, base flow in the river has increased as a r

Documentation and description of the digital spatial data base for southern California Regional Aquifer-System Analysis Program, Santa Clara-Calleguas Basin, Ventura County, California
This report documents the geographic information system map layers and data files generated for the Santa Clara-Calleguas Basin, Ventura County, as part of a Regional Aquifer- System Analysis of southern California from 1989 to 1995. Thirty-six map layers and four data files are maintained in this geographic information system data base. The map layers cover the Santa Clara-Calleguas drainage basi

Comparison of 1972 and 1996 water levels in the Goleta central ground-water subbasin, Santa Barbara County, California
Ground-water levels for 1996 were compared with 1972 water levels to determine if a "drought buffer" currently exists. The drought buffer was defined previously, in a litigated settlement involving the Goleta Water District, as the 1972 water level in the Central ground-water subbasin. To make this deter mination, a network of 15 well sites was selected, water levels were measured monthly from Apr
