Development and calibration of a two-dimensional digital model for the analysis of the ground-water flow system in the San Antonio Creek Valley, Santa Barbara County, California
Peter Martin
1985, Water-Resources Investigations Report 84-4340
A two-dimensional finite-difference model was used to simulate ground-water flow conditions in San Antonio Creek valley. The model was calibrated to simulate steady-state conditions as approximated by ground-water conditions in 1943 and transient conditions during the period 1944-77. The transmissivity of the aquifer and the vertical hydraulic conductivity of the...

Water-quality reconnaissance of selected water-supply lakes in eastern Kansas
L. M. Pope, J. A. Arruda, A.E. Vahsholtz
1985, Water-Resources Investigations Report 85-4058
Data collected for 19 public water-supply lakes in eastern Kansas during spring-fall 1983 were statistically analyzed to describe relationships between water-quality constituents and lake and watershed physical characteristics. A large range was observed in mean concentrations of total nitrite plus nitrate nitrogen, total ammonia nitrogen, total phosphorus, total organic carbon,...

1985, Open-File Report 85-85
A twenty-four hour injection of chloride and sodium was made into Leviathan Creek, Alpine County, California to aid interpretation of the coupled interactions between physical transport processes and geochemical reactions. Leviathan Creek was chosen because it receives acid mine drainage from Leviathan Mine, an abandoned open-pit sulfur mine. Water samples...

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...
