Traveltime and longitudinal dispersion in Illinois streams
Julia B. Graf
1986, Water Supply Paper 2269
Twenty-seven measurements of traveltime and longitudinal dispersion in 10 Illinois streams made from 1975 to 1982 provide data needed for estimating traveltime of peak concentration of a conservative solute, traveltime of the leading edge of a solute cloud, peak concentration resulting from injection of a given quantity of solute, and...
Ground-water movement and effects of coal strip mining on water quality of high-wall lakes and aquifers in the Macon-Huntsville area, north-central Missouri
D. C. Hall, R. E. Davis
1986, Water-Resources Investigations Report 85-4102
Glacial drift and Pennsylvanian bedrock were mixed together forming spoil during pre-reclamation strip mining for coal in north-central Missouri. This restructuring of the land increases the porosity of the material, and increases aqueous concentrations of many dissolved constituents. Median sodium and bicarbonate concentrations were slightly greater, calcium 5 times greater,...
Exploration for areas suitable for ground-water development, central Connecticut Valley lowlands, Massachusetts
B. P. Hansen
1986, Water-Resources Investigations Report 84-4106
Drilling and geophysical borehole logs for a 25-sq-mi section of the Connecticut River valley lowlands area of Amherst, Hadley, and Sunderland, Massachusetts, indicate that the area is mostly underlain by fine-grained lacustrine deposits. Nine test wells ranging in depth from 100 to 303 ft completely penetrate the unconsolidated valley fill....
Delineating recharge areas for stratified-drift aquifers in Connecticut with geologic and topographic maps
E. H. Handman
1986, Water-Resources Investigations Report 83-4230
Stratified-drift aquifers, the major source of large quantities of groundwater in Connecticut, are recharged principally by (1) precipitation that infiltrates the land surface overlying the aquifer and percolates downward to the saturated zone, (2) subsurface inflow of groundwater from adjacent till-and-bedrock uplands, and (3) surface water that infiltrates through streambed...
Bedrock topography of northwest Iowa
R.E. Hansen, D. L. Runkle
1986, IMAP 1726
Bedrock in Iowa (Hershey, 1969) generally is overlain by deposits of glacial drive and alluvium. The drift, consisting of glacial till and glacial outwash, ranges in thickness from zero to more than 500 feet in western Iowa; the alluvium in stream valleys ranges in thickness from less than 1 foot...
Effects of detention on water quality of two stormwater detention ponds receiving highway surface runoff in Jacksonville, Florida
P. S. Hampson
1986, Water-Resources Investigations Report 86-4151
Water and sediment samples were analyzed for major chemical constituents, nutrients, and heavy metals following ten storm events at two stormwater detention ponds that receive highway surface runoff in the Jacksonville, Florida, metropolitan area. The purpose of the sampling program was to detect changes in constituent concentration with time of...
Areal and temporal variability of selected water-quality characteristics in two hydrologic-benchmark basins in the northeastern United States
R.A. Hainly, J.R. Ritter
1986, Water-Resources Investigations Report 85-4025
Two U.S. Geological Survey National Hydrologic Benchmark stations--Young Womans Creek near Renovo, Pennsylvania and Esopus Creek at Shandaken, New York--were studied to (1) define, both areally and temporally, variations of stream acidity and other water quality characteristics within the basins; (2) evaluate how well the data collected at the Benchmark...
A description of the hydrologic system and the effects of coal mining on water quality in the East Fork Little Chariton River and the alluvial aquifer between Macon and Huntsville, north-central Missouri
D. C. Hall
1986, Water-Resources Investigations Report 86-4160
The quality of surface and groundwater has been affected by abandoned strip mines and by abandoned underground mines in a 110-sq mi subbasin of the East Fork Little Chariton River. More than 14% of the area was strip mined for coal before 1979. The hydrologic system in the area was...
Occurrence and availability of ground water in the Athens region, northeastern Georgia
D. B. Radtke, C.W. Cressler, H.A. Perlman, H.E. Blanchard Jr., K.W. McFadden, Rebekah Brooks
1986, Water-Resources Investigations Report 86-4075
A study was conducted to assess the occurrence and availability of groundwater in the crystalline rocks of the Piedmont area in northeastern Georgia and to determine whether groundwater is a viable alternative or supplemental source for industrial, public and private supplies. The area is underlain by a variety of metamorphic...
Map showing landslides in California that have caused fatalities or at least $1,000,000 in damages from 1906 to 1984
Fred Taylor, E. E. Brabb
1986, Miscellaneous Field Studies Map 1867
Understanding where landslide processes in California have been most severe is helpful in determining priorities for landslide mapping, mitigation measures, and preparedness planning. Although a few studies of landslide damage and fatalities have been published (see sources of data 12, 17, 34, 36, 40), and many more reports mention landslide...
Seismicity map of the state of Utah
C. W. Stover, B.G. Reagor, S. T. Algermissen
1986, Miscellaneous Field Studies Map 1856
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Utah, even though earthquakes...
Digital data base of lakes on the North Slope, Alaska
Kim-Marie Walker, James York, Dennis Murphy, C. E. Sloan
1986, Water-Resources Investigations Report 86-4143
The National Mapping Division and Water Resources Division of the U.S. Geological Survey have produced a digital data base of approximately 23,330 lakes on the North Slope of Alaska. The inventoried region consists of the area north of the 69th parallel and is composed of sixteen 1° x 3° quadrangles....
