Numerical simulation of ground-water flow in the central part of the western San Joaquin Valley, California
Kenneth Belitz, Steven P. Phillips, Jo Ann M. Gronberg
1993, Water Supply Paper 2396
The occurrence of selenium in agricultural drain water in the central part of the western San Joaquin Valley, California, has focused concern on strategies for managing shallow, saline ground water. To assess alternatives to agricultural drains, a three-dimensional, finite-difference numerical model of the regional groundwater flow system was developed. This...
