Quality of storm-water runoff, Mililani Town, Oahu, Hawaii, 1980-84
Cheryl M. Yamane, Marty G. Lum
1985, Water-Resources Investigations Report 85-4265
Storm water runoff and rainfall data were collected at two urban sites in Mililani Town, Oahu, Hawaii between September 1980 and August 1984. The data included results from analyses of 300 samples of storm water runoff. Turbidity, suspended solids, Kjeldahl nitrogen, and phosphorus concentrations exceeded the State of Hawaii Department...
Approximate potentiometric surface for the aquifer unit A2, Southeastern Coastal Plain aquifer system of the United States, prior to development
V.A. Stricker
1985, Water-Resources Investigations Report 85-4019
A generalized potentiometric surface map prepared as part of the southeastern United States, Regional Sand Aquifer-System Analysis defines the altitude of water levels under conditions prior to development for aquifer unit A2, the upper group of aquifers in the sand aquifer system. Aquifer unit A2, consisting of lower Tertiary sands,...
Spirit Lake dam-failure flood routing assessment
D. L. Kresch
1985, Open-File Report 82-770
Potential clear-water floodflows resulting from uncontrolled breaching by Spirit Lake of a debris dam deposited by the May 18 , 1980, eruption of Mount St. Helens, Washington, were evaluated. U.S. Geological Survey dam-break model K-634 was utilized, first to compute clear-water flood hydrographs for various hypothetical breach scenarios, and then...
An example expert system for the interpretation of depositional environments
K. B. Krystinik
1985, Open-File Report 85-30
During 1983 the U.S. EPA requested the U.S. Geological Survey and the Missouri Department of Natural Resources to study the geology, water movement, and sediment characteristics of Sugar, Romaine, and Rock Creek basins in Jefferson County, Missouri. The information was needed because the EPA had confirmed the presence of dioxin...
Water-quality assessment and wastewater-management alternatives for Dardenne Creek in St. Charles County, Missouri
W.R. Berkas, J. R. Lodderhose
1985, Water-Resources Investigations Report 85-4120
The quality of water in the 15 mile downstream reach of Dardenne Creek in St. Charles County, Missouri, was assessed to determine if it met the Missouri water quality standards. Concentrations of dissolved oxygen and total ammonia failed to meet water quality standards downstream from the Harvester-Dardenne and St. Peters...
Potentiometric surfaces of the coastal plain aquifers of South Carolina prior to development
Walter R. Aucott, Gary K. Speiran
1985, Water-Resources Investigations Report 84-4208
Characteristics of the Coastal Plains aquifers of South Carolina are being studied as a part of the Regional Aquifer Systems Analysis program of the U.S. Geological Survey. A framework has been developed to best represent the hydrology of the Coastal Plain aquifers by dividing them into a system of five...
Hydrology of Lake Placid and adjacent area, Highlands County, Florida
D. Briane Adams, Yvonne E. Stoker
1985, Water-Resources Investigations Report 84-4149
The study conducted during 1982-83, documents hydrologic conditions in Lake Placid and surrounding areas of Florida. Lake-stage data indicate that the 2- to 50-year flood stage ranges from 93.9 to 96.2 ft. Lake stage is reflected by annual departure of precipitation of the previous year from long-term average. A bathymetric...
Regional geochemical study of the felsic plutonic rocks in the Nuqrah Quadrangle, sheet 25E, Kingdom of Saudi Arabia
W. E. Hall, David Dellinger, G.I. Selner
1985, Open-File Report 85-25
A regional geochemical investigation of the felsic plutonic rocks of the Nuqrah quadrangle, sheet 25 E, Kingdom of Saudi Arabia, in which pan concentrates of 384 wadi samples, and 145 rock samples, were collected, defined two separate and distinct anomalous areas. One area contains Jabal Tuwalah and Jabal Awja, and...
Geohydrology of the Irondequoit Creek Basin near Rochester, New York
Richard M. Yager, Phillip J. Zarriello, William M. Kappel
1985, Water-Resources Investigations Report 84-4259
Geohydrologic information on the area within and surrounding the Irondequoit Creek basin near Rochester, in north-central New York, is presented on five maps at 1:24,000 scale indicating: (1) locations of glacial geomorphic features, (2) surficial geology, (3) soil permeability, (4) potentiometric-surface altitude and directions of groundwater movement, and (5) groundwater...
Study and interpretation of the chemical characteristics of natural water
John David Hem
1985, Water Supply Paper 2254
The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities. Broad interrelationships among these processes and...
Occurrence of saltwater in the alluvial aquifer in the Boeuf-Tensas Basin, Arkansas
D. J. Fitzpatrick
1985, Water-Resources Investigations Report 85-4029
The occurrence of saline water in the alluvial aquifer in the Boeuf-Tensas basin in southeastern Arkansas has been of increasing concern. A band of saline water containing chloride concentrations of greater than 50 milligrams per liter extends through the entire length of the basin. The most severely affected area is...
