Water resources data for Hawaii and other Pacific areas, water year 1977: Volume 1. Hawaii
Water Resources Division, U.S. Geological Survey
1978, Water Data Report HI-77-1
Volume 1 of water resources data for the 1977 water year for Hawaii and other Pacific Areas consist of records of stage, discharge, and water quality of streams; and water levels and water quality in wells and springs. This report contains discharge records for 114 gaging stations; water quality for...
Water table in the surficial aquifer and potentiometric surface of the Floridan Aquifer in selected well fields, west-central Florida, May 1978
R. M. Wolansky, L. R. Mills, W. M. Woodham
1978, Open-File Report 78-939
The water table in the surficial aquifer and the potentiometric surface of the Floridan aquifer in a 1,200-square-mile area in west-central Florida are mapped semiannually by the U.S. Geological Survey. Maps are prepared showing water levels measured in wells each May to coincide with seasonal low levels, and each September...
Agricultural land use and water quality in the upper St. Joseph River basin, Michigan
T. Ray Cummings
1978, Open-File Report 78-950
Land use in the upper St. Joseph River basin of south-central Michigan is primarily agricultural. In the 144-square-mile area, the chemical and physical characteristics of water are determined by the climate and soils, as well as by land conservation practices. Municipal waste discharges affect water quality at some locations, as...
Reconnaissance geotechnical study of the Lucerne Granite, Maine
Sharon F. Diehl, Fitzhugh T. Lee
1978, Open-File Report 78-862
Physical properties, including density and strength, of the Lucerne Granite (Wing, 1958) vary because of inhomogeneities caused by fracturing and differences in texture. Two granitic facies were found: a coarse-grained variety in the southern part of the body and near the edges of the pluton and a medium-grained porphyritic variety...
Principles of computer processing of Landsat data for geologic applications
James V. Taranik
1978, Open-File Report 78-117
The main objectives of computer processing of Landsat data for geologic applications are to improve display of image data to the analyst or to facilitate evaluation of the multispectral characteristics of the data. Interpretations of the data are made from enhanced and classified data by an analyst trained in geology....
Calibration of a simple oilspill trajectory model using the Argo Merchant spill
Timothy Wyant
1978, Open-File Report 78-334
An oil spill risk analysis was conducted to determine the relative envionmental hazards of developing oil in different regions of the Eastern Gulf of Mexico Outer Continental Shelf lease area. The study analyzed the probability of spill occurrence, likely paths of the spills, and locations in space and time of...
