Expert Pattern Recognition for Pollution Source Identification
This paper presents an approach for developing an Expert System to aid the identification of locations and magnitudes of a finite number of groundwater pollution sources. A pattern recognition...
Debris Flows and Hyperconcentrated Streamflows
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that...
Recovery of Freshwater Stored in Saline Aquifers in Peninsular Florida
Subsurface freshwater storage has been operationally tested at seven sites in central and south Florida. Injection was into a high chloride water aquifer at six sites, and into a high...
Conjunctive Use and Managed Groundwater Recharge: Engineering and Politics in Arid Lands
In regions with alluvial groundwater basins, increasing consumer demands for water, irregular surface water flows, and high evapotranspiration rates, managed recharge and long-term conjunctive...
America's National Forests: Our Ultimate Water Source
National Forest System lands in the western United States make up 21 percent of the total land area but yield over 55 percent of the region's streamflow and provide more than...
Water Management of the Snowy Mountains Scheme Australia
The Snowy Mountains Scheme in south-eastern Australia provides a classic example of Water Resources Planning and Management on a National scale. The Scheme provides mainly peak electricity...
River Basin Network Model for Conjunctive Use of Surface and Groundwater
A generalized river basin computer model called CONSIM is presented for management of the conjunctive use of surface and subsurface storage in an interconnected stream-aquifer system....
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...
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...
An Evaluation of Sediment Resuspension Parameterizations
The recent attention to managing surface water toxic substances has resulted in a number of modeling approaches, all of which to a great or lesser extent require accurate treatment of...
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...
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...
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...
