Economics of Groundwater-Pumping Level Statutes
Pumping from one well may lower the water table in another to the point where pumping from it becomes unfeasible. Problems exist in allocating the increased costs of pumping caused by...
San Joaquin Valley Hydrologic-Economic Model
The rapid development of agriculture in the San Joaquin Valley has resulted in increased ground water pumpage. Increasing energy costs coupled with increasing pumping lifts have a major...
Groundwater Basin Storage in Southern California
The feasibility of implementing a groundwater storage program in the Chino Groundwater Basin (Chino Basin) to increase the firm yield of the SWP (California State Water Project) is considered....
Ground Water Economics in the San Joaquin Valley
Ground water pumping in the San Joaquin Valley to supplement surface water supplies has increased from about 200 thousand acre-feet per year at the beginning of this century to nine million...
Drip Irrigated Cotton: Economics and Water Savings
Groundwater withdrawals for cotton production in the arid Southwest account for about 15 percent of all groundwater withdrawals. In Arizona, cotton's proportion of groundwater...
Testing for Salt Damage
Salts used to melt snow can contribute to deterioration of concrete structures. Various tests were used to determine the extent of damage in two structures in Rochester, N.Y. One is an...

Vertical Behavior of Two 16-Year Old Drilled Shafts
Vertical load tests were performed on drilled shafts subject to lateral confining and heaving pressures from expansive soil over 16 years. Results indicated mobilized skin friction equal...
Consolidation Performance of Soft Clays: Part 2. Predictions
The simplified version of the model described in Part 1 was used to predict the short-term performance of the St. Alban test fill. The long-term predictive capability of the model was...
Consolidation by Sand Drain in Anisotropic Ground
The author reduces Biot's equations of consolidation into a single governing equation with the excess pore water pressure as the only unknown function and derives the theory...
Time and Stress Dependent Compression in Soft Sediments
Results are presented for laboratory experiments using a typical estuarine mud settling from a slurry in columns of 100mm diameter. Measurements have been made of density and pore water...
