Evaluation of the streamflow-data program in Pennsylvania
Herbert N. Flippo Jr.
1982, Water-Resources Investigations Report 82-21
The stream-gaging program in Pennsylvania is subject to budgetary constraints in the next several years. Elimination of those gaging stations that have no current-purpose use and little utility in providing regional flow-characteristic information is the most effective way to reduce costs. The efficient design of a network of gaging stations for obtaining regional information...

David P. Brown
1982, Water-Resources Investigations Report 82-37
The average annual rainfall in the Manasota Basin is 53.7 inches , and annual evapotranspiration is about 39 inches. Annual runoff from gaged parts of the Basin ranges from about 13 to 17 inches per year. Streamflow in the upland areas diminishes rapidly following the end of the rainy season...
A plan for hydrologic investigations of in situ, oil-shale retorting near Rock Springs, Wyoming
Kent C. Glover, E. A. Zimmerman, L. R. Larson, J.C. Wallace
1982, Open-File Report 82-758
The recovery of shale oil by the in-situ retort process may cause hydrologic impacts, the most significant being ground-water contamination and possible transport of contaminants into surrounding areas. Although these impacts are site-specific, many of the techniques used to investigate each retort operation commonly will be the same. The U.S....

1982, FWS/OBS 82/10.27
Habitat preferences of the yellow warbler (Dendroica petechia) are described in this publication. It is one of a series of Habitat Suitability Index (HSI) models and was developed through an analysis of available information on the species-habitat requirements of the species. Habitat use information is presented in a review of...

1982, Water-Resources Investigations Report 82-4025
This report describes modifications incorporated into the finite-difference model for simulation of groundwater flow in three dimensions. These modifications extend the application of this model to simulations involving head-dependent sources and sinks (i.e., rivers, evapotranspiration, and springs or drains). Other modifications are made that enhance the iterative-solution process of the...

Ground-water applications of remote sensing
Gerald K. Moore
1982, Open-File Report 82-240
Remote sensing can be used as a tool to inventory springs and seeps and to interpret lithology, structure, and ground-water occurrence and quality. Thermograms are the best images for inventory of seeps and springs. The steps in aquifer mapping are image analysis and interpretation and ground-water interpretation. A ground-water interpretation...

R. J. Lindgren
1982, Water-Resources Investigations Report 82-4011
Irrigation pumpage was determined for parts of Kearny and Finney Counties in Southwestern Kansas using crop-acreage data and consumptive, irrigation-water requirements. Irrigated acreages for 1974-80 were compiled for wheat, grain sorghum, corn, and alfalfa using records from the U.S. Agricultural Stabilization and Conservation Service. Consumptive-irrigation requirements were computed using a...
