Technique for estimating the 2- to 500-year flood discharges on unregulated streams in rural Missouri
Terry W. Alexander, Gary L. Wilson
1995, Water-Resources Investigations Report 95-4231
A generalized least-squares regression technique was used to relate the 2- to 500-year flood discharges from 278 selected streamflow-gaging stations to statistically significant basin characteristics. The regression relations (estimating equations) were defined for three hydrologic regions (I, II, and III) in rural Missouri. Ordinary least-squares regression analyses indicate that drainage...
Geohydrology and simulation of ground-water flow near Los Alamos, north-central New Mexico
P. F. Frenzel
1995, Water-Resources Investigations Report 95-4091
An existing model was modified in recognition of new geohydrologic interpretations and adjusted to simulate hydrographs in well fields in the Los Alamos area. Hydraulic-head drawdowns at the Buckman well field resulting from two projected ground-water-withdrawal alternatives were estimated with the modified model.
