Spatial variation in total element concentration in soil within the Northern Great Plains coal region and Regional soil chemistry in Bighorn and Wind River basins, Wyoming and Montana
R. C. Severson, R.R. Tidball
1979, Professional Paper 1134-A,B
PART A: To objectively determine the changes in chemical character of an area subjected to mining and reclamation, prior information is needed. This study represents a broadscale inventory of total chemical composition of the surficial materials of the Northern Great Plains coal region (western North and South Dakota, eastern Montana,...
Status of surface-water modeling in the U.S. Geological Survey
Marshall E. Jennings, Nobuhiro Yotsukura
1979, Circular 809
The U.S. Geological Survey is active in the development and use of models for the analysis of various types of surface-water problems. Types of problems for which models have been, or are being developed, include categories such as the following: (1)specialized hydraulics, (2)flow routing in streams, estuaries, lakes, and reservoirs,...
Water quality of selected streams in the coal area of east-central Montana
P. W. McKinley
1979, Water-Resources Investigations Report 78-142
In October 1975 the U.S. Geological Survey established a network of nine data-collection stations on eight streams in Montana to monitor water quality in potential coal-mining areas. The report summarizes and evaluates the water-quality data that have been collected during the first 2 years (3 years for 1 station) of...
Effects of seepage from fly-ash settling ponds and construction dewatering on ground-water levels in the Cowles unit, Indiana Dunes National Lakeshore, Indiana
William R. Meyer, Patrick Tucci
1979, Water-Resources Investigations Report 78-138
Part of the Indiana Dunes National Lakeshore shares a common boundary with the Northern Indiana Public Service Company (NIPSCO). This area is underlain by unconsolidated deposits approximately 180 feet thick. NIPSCO accumulates fly ash from the burning of coal in electric-power generating units in settling ponds. Seepage from the ponds...
Water budget and hydraulic aspects of artificial recharge, south coast of Puerto Rico
J. E. Heisel, Jose Raul Gonzalez
1979, Water-Resources Investigations Report 78-58
An analog model was used to evaluate ground-water conditions on the south coast of Puerto Rico. Water levels during a normal period and during an extended drought were simulated. Recharge and discharge values are reported. The model was also used to evaluate the possibilities of using treated waste water to...
Digital model of the Hollister Valley ground-water basin, San Benito County, California
G.W. Kapple
1979, Water-Resources Investigations Report 79-32
A two-dimensional finite-difference digital model was constructed to simulate effects of proposed pumping and recharge schemes on water levels in the Hollister Valley ground-water basin. Pumping rates in the valley are expected to increase from 24,000 acre-feet per year in 1968 to an ultimate rate of 38,500 acre-feet per year....
Coal resources of southeastern Massachusetts assessed in 1942
Newton Earl Chute
1979, Open-File Report 79-1140
Large easily mined coal deposits of usable quality would be of great value to Massachusetts, particularly in war time. Every effort has been made in this study to evaluate the probable occurrence, quantity, and quality of the coal deposits in southeastern Massachusetts but unfortunately it is impossible from surface observations...
Flood characteristics of Alaskan streams
R. D. Lamke
1979, Water-Resources Investigations Report 78-129
Peak discharge data for Alaskan streams are summarized and analyzed. Multiple-regression equations relating peak discharge magnitude and frequency to climatic and physical characteristics of 260 gaged basins were determined in order to estimate average recurrence interval of floods at ungaged sites. These equations are for 1.25-, 2-, 5-, 10-, 25-,...
