Automatic Controls for Industrial Water System
An 8-mile pipeline and associated facilities along its route are controlled by a centralized system consisting of a master station and four remotes. Each site employs Westinghouse programmable...
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...
River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
Environmental Engineering
The purpose of the Annual Conference on Environmental Engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of the many environmental...
Water Today and Tomorrow
These conference proceedings include 87 papers dealing with irrigation-related topics concerning water supplies, water quality, legal and social infrastructure, irrigation projects and...
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...
Application of Finite Strain Consolidation Theory for Engineering Design and Environmental Planning of Mine Tailings Impoundments
A knowledge of the consolidation behavior of mine tailings, during and after deposition, is important in estimating final impoundment capacity, rate and pore fluid expulsion during and...
Convection-Diffusion Analysis of Sedimentation in Initially Dilute Solids-Suspensions
The settling of suspended solids in solids-suspensions is treated from the viewpoint of the relative fluxes established as a result of the upward diffusion of water and the downward convection...
Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...
New Tools Help Find Flaws
Certain electromagnetic tools for nondestructive evaluation of existing infrastructure, though not widely used, can cut cost and time of identifying flaws in existing infrastructure. Five...
Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...
Infrastructure: Money and Methods
State and local governments have started to cope with their infrastructure problems by passing bond issues, establishing infrastructure banks to centralize resources and decision making,...
Selecting an Economical Water Main Rehab
Many miles of aging water mains exist with carrying capacities that are less than half of what they were when new. Engineers must, therefore, stretch every dollar to eliminate deposits...
