Modeling an Alluvial Aquifer with Flood Irrigation
Interaction between an unconfined alluvial aquifer, recharged by flood irrigation, and the associated stream system in a glacial outwash area of Wyoming was studied. The United States...
Optimizing Drain Spacing and Depth Using Steady State Equations
A method is developed for minimizing the total cost of establishing relief drains by choosing appropriate depth and spacing of the drains. Solution graphs are presented for a wide range...
A GIS to Predict Non-Point Source Pollution Potential
The non-point pollution potential of agricultural lands was analyzed using a geographic, computer based system. Bacterial pollution received special emphasis. The system accepts digitally...
Linking Data Base Management and Computer Models
Storing, tabulating, and graphing large volumes of data, not usually a strong point of a computer model, is more appropriate for a data base management system. A blend of these two technologies,...
A Customized Database Management System for Watershed Modeling
When large watershed areas are being studied and continuously monitored, it is desirable to create a database management system (DBMS) that provides the necessary capability to build and...
Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...
Water Infrastructure Maintenance Needs?A Case Study
Adoption of measures to prevent loss of water in many cases is cost-effective. In order to illustrate the magnitude of infrastructure problems of large cities, a test case infrastructure...
The Rx for Relief from Equipment Failure
A predictive maintenance program was developed for a treatment plant with a large number of pieces of critical mechanical equipment. Using an inexpensive, portable vibration meter, data...
Modernizing the Maintenance Function
The Los Angeles County Department of Public Works maintains one of the largest and most complex flood control and water conservation systems in the world. A system study of the maintenance...
An Experimental Study on the Effect of Wastewater Application in Dry Wells and Its Impact on Groundwater
A study was conducted in order to gather accurate information on the effectiveness of dry wells for use in wastewater disposal and the effect of such disposal practice on groundwater....
Port Infrastructure Program in Mexico
In Mexico the policies, guidelines, goals and methodologies refering to transport, are the responsibility of the 'Secretaria de Comunicaciones y Transportes'...
Central Arizona Project Startup
The Central Arizona Project is a water conveyance scheme, lifting and conveying Colorado River water from Lake Havasu on the Colorado River 190 miles to Phoenix and another 150 miles to...
Operations Models of the Columbia Reservoir System
Several of the computer models used in management of the basin's reservoir system are described. Among the models discussed are the Streamflow Synthesis and Reservoir Regulation...
Model to Maximize Releases for Supplemental Generation in a Pump-Storage System
An optimization model has been developed to maximize releases for supplemental power generation in a pump-storage system. The model was developed to aid in the scheduling of pump-storage...
Transferring Conserved Water
The proposal to transfer water salvaged by water conservation programs from one area to another is a new concept. Imperial Irrigation District (District), located in the southeast portion...
Interstate Agreements for Water Transfers
Any state is typically subjected to opposing forces that wish to 1) preserve limited water resources for future in-state uses, or 2) to export that resource for out-of-state use. Statutes...
Rainfall-Loss Parameter Estimation for Illinois
The U. S. Geological Survey is currently conducting an investigation to estimate values of parameters for two rainfall-loss computation methods used in a commonly used flood-hydrograph...
Groundwater Quality Monitoring in the New York Metropolitan Area: Statistical Alternatives
The need for development of groundwater monitoring strategies for the New York metropolitan area with emphasis on statistical analysis has been investigated in this study. Statistical...
Corps of Engineers Automation of Real-Time Water Control Management
Automation of real-time water control management activities has enabled the Corps to keep pace with an ever increasing workload in a time of fiscal constraint and reduced manpower. Where...
Sedimentation Problems of the California Aqueduct
The California Aqueduct crosses the alluvial fans of many intermittent streams on the west side of the San Joaquin Valley. At two sites where watershed sediment yields were underestimated,...
