Tidal-flow, circulation, and flushing changes caused by dredge and fill in Tampa Bay, Florida
Carl R. Goodwin
1987, Water Supply Paper 2282
Tampa Bay, Florida, underwent extensive physical changes between 1880 and 1972 because of construction of causeways, islands, channels, and shoreline fills. These changes resulted in a progressive reduction in the quantity of tidal water that enters and leaves the bay. Dredging and filling also changed the magnitude and direction of...

Hydrology of the White Tail Butte area, northern Campbell County, Wyoming
M.E. Lowry, J.G. Rankl
1987, Water-Resources Investigations Report 82-4117
Quantity of runoff and peak discharge from one small basin in the White Tail Butte area, determined from a calibrated rainfall-runoff model, is less than the quantity computed using results of a regional study. The difference is caused by the extensive beds of exposed, permeable clinker in the area. Potentiometric...
Possible changes in ground-water flow to the Pecos River caused by Santa Rosa Lake, Guadalupe County, New Mexico
D. W. Risser
1987, Water-Resources Investigations Report 85-4291
In 1980 Santa Rosa Dam began impounding water on the Pecos River about 7 miles north of Santa Rosa, New Mexico, to provide flood control, sediment control, and storage for irrigation. Santa Rosa Lake has caused changes in the groundwater flow system, which may cause changes in the streamflow of...
Floods in Kansas and techniques for estimating their magnitude and frequency on unregulated streams
R.W. Clement
1987, Water-Resources Investigations Report 87-4008
Techniques are presented for generalizing the skewness coefficient of log-Pearson Type III distributions of annual maximum discharges and for flood magnitudes that have selected recurrence intervals from 2 to 100 yr. A weighted least-square (WLS) regression model was used to generalize the coefficients of station skewness that resulted in a...
Simulation of ground-water flow near the nuclear-fuel reprocessing facility at the Western New York Nuclear Service Center, Cattaraugus County, New York

Geology and hydrology of the Onondaga aquifer in eastern Erie County, New York, with emphasis on ground-water-level declines since 1982
W. W. Staubitz, Todd S. Miller
1987, Water-Resources Investigations Report 86-4317
The Onondaga aquifer is a nearly flat-lying, 25- to 110-foot-thick, cherty limestone with moderately developed karst features such as sinkholes, disappearing streams, and solution-widened joints. Most groundwater moves through solution-widened bedding planes, although some moves through vertical joints. The yield of water from 42 wells ranges from 3 to 100...
Potential for pollution of the Upper Floridan aquifer from five sinkholes and an internally drained basin in west-central Florida
J.T. Trommer
1987, Water-Resources Investigations Report 87-4013
Sinkholes are natural and common geologic features in west-central Florida, which is underlain by water soluble limestone deposits. Dissolution of these deposits is the fundamental cause of sinkhole development. Sinkholes and other karst features are more pronounced in the northern part of the study area, but sinkhole activity has occurred...
