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...
Gully Incision Prediction on Reclaimed Slopes
An investigation was conducted to estimate the potential of gully intrusion into reclaimed waste impoundments. A series of eight reclaimed impoundments exhibiting gully intrusions were...
Stochastic Design of Wastewater Storage Ponds
The authors combine the principle of mass conservation with basic ideas from probability theory and then apply Monte Carlo simulation techniques to develop a family of design charts called...
Parameter Optimization of Dynamic Routing Models
The methodology utilizes approximate cross-sectional properties represented by separate power functions for channel and floodplain, and a very efficient optimization algorithm for determining...
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....
Investigating and Treating Chromium in Ground Water at a Wood Treater in California
A wood treating facility, operating for more than five years without required permits, contaminated soil and ground water on and offsite. The company moved slowly in response to enforcement...
Remedial Action Alternatives for Groundwater Contamination
Preliminary remedial action alternatives are formulated for a site contaminated by heavy metals. The results of soils and hydrogeologic investigations are summarized and three corrective...
Liquid Waste Pollution from a Sugar Cane Industry
The water pollution survey as performed in this study, indicates that all liquid wastes from the mill are segregated. The chemical waste sewerage systems supposedly conveys these wastes...
On the Ship's Waterways Passing Through Bridges
This paper reports on a study of bridge openings that serve as waterways, in view of the analysis of ship collision accidents. For the purpose of this study, cases of ship collision accidents...
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...
Intrastate and Interstate Water Transfers
Riparian states generally do not permit transfers of water outside the watershed of origin, while the opposite is true in the appropriation states provided there is no harm to existing...
Evolving Institutions for Water Transfer in the U.S.
A major source of constraint is state water allocation law, which defines rights for water use and development, including in some cases restrictions on place of use that limit transfer....
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...
