1981, Open-File Report 81-343
Area 4 (one of the 24 hydrologic areas defining the Eastern Coal Province) is located at the northern end of the Eastern Coal Province in eastern Ohio, northern West Virginia, and western Pennsylvania. It is part of the upper Ohio River basin, which includes the Beaver, Mahoning, and Shenango Rivers....
Proceedings of Conference XIII, evaluation of regional seismic hazards and risk
Barbara B. Charonnat (compiler)
1981, Open-File Report 81-437
The participants in the conference concluded that a great deal of useful research has been performed in the national Earthquake Hazards Reduction Program by USGS and non-USGS scientists and engineers and that the state-of-knowledge concerning the evaluation of seismic hazards and risk has been advanced substantially. Many of the technical...
Geology and hydrology for environmental planning in Marquette County, Michigan
F. R. Twenter
1981, Water-Resources Investigations Report 80-90
Marquette County, in the glaciated area of the Upper Peninsula of Michigan, includes 1,878 square miles. Precipitation averages 32 inches per year. Bedrock and glacial deposits contain materials that are good aquifers. Sedimentary bedrock units generally yield sufficient water for domestic supply and, in places, may yield more than 100...
Floods of September 16, 1975 in the Tallaboa Valley, Puerto Rico
Karl G. Johnson
1981, Water-Resources Investigations Report 80-1283
This report provides a record of the flood of September 16, 1975, and associated hydrologic data. These data can be used in making rational decisions in formulating effective flood-plain regulations that would minimize flood problems in the Tallaboa Valley.The Tallaboa Valley (fig. 1) lies on the southwestern coast of Puerto...
Shallow ground-water conditions and vegetation classification, central Volusia County, Florida
Edward P. Simonds Jr., Benjamin F. McPherson, Peter W. Bush
1981, Open-File Report 80-752
In the early 1970's, the Volusia County Council recognized the need to develop new sources of freshwater for future growth and development. County Council, using data from the U.S. Geological Survey and private consultants, concluded that the central wetlands were an optimal area for well-field development. With this in mind,...
The ecology of intertidal oyster reefs of the South Atlantic Coast: A community profile
Leonard M. Bahr, William P. Lanier
1981, FWS/OBS 81/15
The functional role of the intertidal oyster reef community in the southeastern Atlantic coastal zone is described. This description is based on a compilation of published data, as well as some unpublished information presented as hypotheses. The profile is organized in a hierarchical manner, such that relevant details of reef oyster...
Mapsat conceptual design; system overview
Alden P. Colvocoresses
1981, Open-File Report 81-26
After more than 10 years of study and applications of Earth imaging satellite systems, the U. S. Geological Survey has conceptually defined a candidate Operational Land Remote Sensing Satellite. A conceptual design study of this system, known as MAPSAT, has been completed by Itek Optical Systems, a division of Itek...
Data on ground-water quality with emphasis on radionuclides, Sarasota County, Florida
Horace Sutcliffe, R. L. Miller
1981, Open-File Report 80-1223
A compilation of analytical results are presented for selected radiochemical and chemical characteristics for 200 groundwater samples collected from 92 wells in Sarasota County, Fla. Radium-226 analysis was made on 160 of the water samples and 80 samples equaled or exceeded the 5 picocuries per liter maximum contaminant level established...
Time-of-travel studies for the Little Androscoggin River, Maine
William J. Nichols, Barry M. Reed, Fred W. Greenlaw
1981, Open-File Report 81-640
Time-of-travel studies were conducted at flow durations of 20, 80, and 95 percent on the Little Androscoggin River from South Paris to Auburn, Maine. The river is about 29.3 miles long, and drains an area of about 354 square miles at its mouth.Traveltimes were determined by tracing the movement of...

William C. Sinclair, Ronald C. Reichenbaugh
1981, Open-File Report 81-212
Fourteen interconnected lakes in and around the city of Winter Haven, Polk County, Fla., form the Winter Haven Chain of Lakes. Levels of the lakes during the spring of 1976 were at a record low stage for the 31 years of record. During 1960-76, rainfall had been below average for...
Tracing ground-water movement by using the stable isotopes of oxygen and hydrogen, upper Penitencia Creek alluvial fan, Santa Clara Valley, California
K. S. Muir, Tyler B. Coplen
1981, Water Supply Paper 2075
Starting in 1965 the Santa Clara Valley Water District began importing about i00,000 acre-feet per year of northern California water. About one-half of this water was used to artificially recharge the Upper Penitencia Creek alluvial fan in Santa Clara Valley. In order to determine the relative amounts of local ground...
