Detailed and reconnaissance mapping of the Devils Hole, Nevada, area has improved definition of the local geologic structure within a regional carbonate aquifer near its primary discharge points -- the springs of Ash Meadows. Several formerly unmapped calcite veins, and other young calcite-lined paleo-spring feeder zones were found, as well...
Water resources of Borrego Valley and vicinity, San Diego County, California: Phase 2 - Development of a ground-water flow model
H. T. Mitten, G. C. Lines, Charles Berenbrock, T. J. Durbin
1988, Water-Resources Investigations Report 87-4199
Because of the imbalance between recharge and pumpage, groundwater levels declined as much as 100 ft in some areas of Borrego Valley, California during drinking 1945-80. As an aid to analyzing the effects of pumping on the groundwater system, a three-dimensional finite-element groundwater flow model was developed. The model was...
Hydrologic data for computation of sediment discharge: Toutle and North Fork Toutle Rivers near Mount St. Helens, Washington, water years 1980-84
Dallas Childers, Stephen E. Hammond, William P. Johnson
1988, Open-File Report 87-548
