Hydrologic data of the coastal drainage basins of southeastern Massachusetts, Plymouth to Weweantic River, Wareham
John R. Williams, Gary D. Tasker, Richard E. Willey
1977, Open-File Report 77-186
The principal basins in this study in southeastern Massachusetts are those of Town Brook, Eel River, and Beaverdam Brook, all draining to Cape Cod Bay; Herring Brook draining to the Cape Cod Canal; and Red Brook, Agawam River, Wankinco River, and Weweantic River, all draining to Buzzards Bay. This report...
Time of travel of solutes in the Tuscarawas River Basin, Ohio, August and September, 1974
Arthur O. Westfall, Earl E. Webber
1977, Open-File Report 77-23
A time-of-travel study was made on a 10.6-mile reach of the Tuscarawas River to determine average velocity and dispersion characteristics between selected points. The reach was divided into five subreaches, and a fluorescent dye used as a tracer material. At about the 50-percent flow-duration level, time-of-travel of the peak concentration...
Dissolved-oxygen regimen of the Willamette River, Oregon, under conditions of basinwide secondary treatment
Walter G. Hines, S. W. McKenzie, D. A. Rickert, F. A. Rinella
1977, Circular 715-I
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Simulated changes in ground-water levels resulting from proposed phosphate mining, west-central Florida; preliminary results
William Edward Wilson
1977, Open-File Report 77-882
A digital model of two-dimensional ground-water flow was used to simulate projected changes in the Floridan aquifer potentiometric surface in 1985 and 2000, resulting from proposed ground-water developments by the phosphate mining industry in west-central Florida. The .model was calibrated under steady-state conditions to simulate the September 1975 potentiometric surface....
Limnology of selected lakes in Ohio, 1975
Robert L. Tobin, John D. Youger
1977, Water-Resources Investigations Report 77-105
Water-quality reconnaissance by the U.S. Geological Survey and Ohio Environmental Protection Agency, to evaluate the status of Ohio's lakes and reservoirs was begun in 1975 with studies of 17 lakes. Spring and summer data collections for each lake included: profile measurements of temperature, dissolved oxygen, pH, and specific conductance; field...
Availability of ground water in the lower Connecticut River basin, southwestern New Hampshire
J. E. Cotton
1977, Water-Resources Investigations Report 77-79
This map scale 1:125,000 presents a preliminary assessment of the availability of ground water in the lower Connecticut River basin in southwestern New Hampshire. It is a generalization of several hydrogeologic factors and provides a guideline for ground-water exploration useful in water- and land-use planning. It does not describe the...
Surficial and applied surficial geology of the Belchertown Quadrangle, Massachusetts
Joseph A. Caggiano
1977, Open-File Report 77-633
Till and stratified drift overlie maturely dissected topography in the Belchertown quadrangle, an area that straddles the New England Upland and Connecticut Valley Lowland in central Massachusetts. Lower Paleozoic, massive quartzo-feldspathic gneiss, quartzite and schist of the Pelham dome and Devonian granodiorite and quartz diorite of the Belchertown intrusive complex...
