Appraisal of water resources in the Hackensack River basin, New Jersey
L.D. Carswell
1976, Water-Resources Investigations Report 76-74
The Hackensack River basin, in the northern part of the New Jersey-New York metropolitan area, includes some of the most highly urbanized areas in the United States as well as a largely undeveloped 23.4 square mile area of tidal marsh referred to as the Hackensack Meadows. Bedrock in the Hackensack...
Computer simulation model of the Pleistocene valley-fill aquifer in southwestern Essex and southeastern Morris counties, New Jersey
Harold Meisler
1976, Water-Resources Investigations Report 76-25
A finite-difference digital computer model was developed to simulate a buried valley-fill aquifer consisting of outwash sand and gravel deposited in a series of valleys cut into bedrock of Triassic age. Till, clay, silt, and muck function as an overlying semiconfining layer. The bedrock which is represented as an unconfined...
Water-quality data for the Southern Ute Indian Reservation, southwestern Colorado
E. Carter Hutchinson, Robert E. Brogden
1976, Open-File Report 76-16
Water-quality data from a study by the U.S. Geological Survey on the Southern Ute Indian Reservation in southwestern Colorado are presented in two tables. The data were collected during 1973-76 from 338 ground-water and surface-water samples. All samples were analyzed for major catons and anions, and selenium and arsenic. Data...
Limnological investigation of six lakes in southeast Alaska
George A. McCoy, William W. Wiggins, Artwin E. Schmidt
1976, Water-Resources Investigations Report 76-122
Limnological data were collected from six lakes in southeast Alaska in 1974. The data include concentrations of major inorganic constituents, nutrients, selected trace metals, total organic carbon, and chlorophyll. Vertical profiles of specific conductance, temperature, dissolved-oxygen saturation, and pH were drawn. With the exception of Redoubt Lake, all of the...
Computer applications for step-backwater and floodway analyses
James O. Shearman
1976, Open-File Report 76-499
A computer program which can be used to computer water-surface profiles for gradually varied, subcritical flow is described. Profiles are computed by the standard step-backwater method. Water-surface profiles may be obtained for both existing stream conditions and for stream conditions as modified by encroachment. The user may specify encroachment patterns...
Flood-frequency analysis for small natural streams in Georgia
Harold G. Golden, McGlone Price
1976, Open-File Report 76-511
Flood information from 104 project basins (0.1 to 20 square miles) and data available from 170 larger basins (20 to 1,500 square miles) are analyzed to provide planners and designers with relations for estimating the magnitude and frequency of flood-peak discharges on small natural streams in Georgia. More than 90...
Water resources of south-central Missouri
E. E. Gann, Edward Joseph Harvey, Don E. Miller
1976, Hydrologic Atlas 550
This atlas describes hydrology in an area of approximately 23 ,000 sq mi and includes all or parts of 38 counties in Missouri. The area is bounded on the north by the southern edge of the Missouri River flood plain, on the east by the Mississippi River and the Plateaus-Lowlands...
Documentation of finite-difference model for simulation of three-dimensional ground-water flow
Peter C. Trescott, S. P. Larson
1976, Open-File Report 76-591
User experience has indicated that the documentation of the model of three-dimensional ground-water flow (Trescott and Larson, 1975) should be expanded. This supplement is intended to fulfill that need. The original report emphasized the theory of the strongly implicit procedure, instructions for using the groundwater-flow model, and practical considerations for...
