Ground-water flow and water quality in northeastern Union County, Ohio
K. S. Wilson
1987, Water-Resources Investigations Report 87-4083
A study was done by the U.S. Geological Survey, in cooperation with the Village of Richwood, Ohio, to determine directions of ground-water flow, ground-water-level fluctuations, and water quality in the northeastern part of Union County. The topography of the study area generally is featureless, and the land surfaces slopes gently eastward...
Relation between ground water and surface water in the Hillsborough River basin, west-central Florida
R. M. Wolansky, T. H. Thompson
1987, Water-Resources Investigations Report 87-4010
The relation between groundwater and surface water in the Hillsborough River basin was defined through the use of: seismic-reflection profiling along selected reaches of the Hillsborough River, and evaluation of streamflow, rainfall, groundwater levels, water quality, and geologic data. Major municipal well fields in the basin are Morris Bridge and...
Geologic map of the Chelan 30-minute by 60-minute quadrangle, Washington
R. W. Tabor, V. A. Frizzell Jr., J. T. Whetten, R. B. Waitt Jr., D. A. Swanson, G. R. Byerly, D. B. Booth, M. J. Hetherington, R. E. Zartman
1987, IMAP 1661
Summary -- The Chelan quadrangle hosts a wide variety of rocks and deposits and display a long geologic history ranging from possible Precambrian to Recent. Two major structures, the Leavenworth and Entiat faults divide cross the quadrangle from southeast to northwest and bound the Chiwaukum 'graben', a structural low preserving...
Effects of proposed highway embankment modifications on water-surface elevations in the lower Pearl River flood plain near Slidell, Louisiana
J. J. Gilbert, R. E. Schuck-Kolben
1987, Water-Resources Investigations Report 86-4129
Major flooding in the lower Pearl River basin in recent years has caused extensive damage to homes and highways in the area. In 1980 and 1983, Interstate Highway 10 and U.S. Highway 190 were overtopped. In 1983, the Interstate Highway 10 crossing was seriously damaged by the flood. The U.S....
Effects of coal strip mining on stream water quality and biology, southwestern Washington
L. A. Fuste, D. F. Meyer
1987, Water-Resources Investigations Report 86-4056
Strip mining for coal in southwestern Washington may be affecting the water quality of streams. To investigate these possible effects, five streams were selected for study of water quality in each of the two coal bearing areas: the Centralia-Chehalis coal district, and Kelso-Castle Rock coal area. In the Centralia-Chehalis coal...
Application of techniques to identify coal-mine and power-generation effects on surface-water quality, San Juan River basin, New Mexico and Colorado
C. L. Goetz, Cynthia G. Abeyta, E.V. Thomas
1987, Water-Resources Investigations Report 86-4076
Numerous analytical techniques were applied to determine water quality changes in the San Juan River basin upstream of Shiprock , New Mexico. Eight techniques were used to analyze hydrologic data such as: precipitation, water quality, and streamflow. The eight methods used are: (1) Piper diagram, (2) time-series plot, (3) frequency...
