Water levels have declined about 30 ft from 1940 to 1980 in part of the Equus beds aquifer in south-central Kansas where the city of Wichita operates a well field. A three-dimensional, finite-difference, groundwater flow model was developed to: (1) Reproduce hydrologic conditions in the flow system between the Equus...
Estimation of selected flow and water-quality characteristics of Alaskan streams
Bruce Parks, R. J. Madison
1985, Water-Resources Investigations Report 84-4247
Although hydrologic data are either sparse or nonexistent for large areas of Alaska, the drainage area, area of lakes, glacier and forest cover, and average precipitation in a hydrologic basin of interest can be measured or estimated from existing maps. Application of multiple linear regression techniques indicates that statistically significant...

Calibration procedure for a daily flow model of small watersheds with snowmelt runoff in the Green River coal region of Colorado
J. M. Norris, R. S. Parker
1985, Water-Resources Investigations Report 83-4263
A calibration procedure was developed for the U.S. Geological Survey 's Precipitation-Runoff Modeling System for watersheds in which snowmelt is the major contributor to runoff. The model uses daily values of air temperature and precipitation as input and the output is mean daily discharge. The procedure appears sufficient to calibrate...
