Reconnaissance of the shallow-unconfined aquifer in Salt Lake Valley, Utah
R. L. Seiler, K.M. Waddell
1984, Water-Resources Investigations Report 83-4272
The shallow-unconfined aquifer in Salt Lake (Jordan) Valley, Utah, seldom is used for domestic or industrial purposes because it yields water slowly and is readily contaminated. The water in the aquifer, however, can flood basements and is a potential source of contamination to other water supplies. In about one-half of...

Application of the conjugate-gradient method to ground-water models
T.A. Manteuffel, D.B. Grove, Leonard F. Konikow
1984, Water-Resources Investigations Report 83-4009
The conjugate-gradient method can solve efficiently and accurately finite-difference approximations to the ground-water flow equation. An aquifer-simulation model using the conjugate-gradient method was applied to a problem of ground-water flow in an alluvial aquifer at the Rocky Mountain Arsenal, Denver, Colorado. For this application, the accuracy and efficiency of the...
