Local Resources in Developing Country Water Supplies
Maximizing the use of local resources in water supply projects can expand markets for locally produced equipment and materials, reduce exports and minimize expenditures of hard currency...

Hydrodynamic Modeling of Bolsa Chica, California, Proposed Wetland Enhancements
The California State Lands Commission (SLC) requested US Army Engineer Waterways Experiment Station (WES), Coastal Engineering Research Center (CERC), to conduct engineering studies for...

Management and Institutional Considerations in Selecting Appropriate Technologies in Water Supply and Sanitation
Rural water supply and sanitation systems in developing countries have had an unacceptably high rate of failure or reduced use. Development planners have not sufficiently considered the...

Incipient Motion Criteria Defining Safe Zones for Salmon Spawning Habitat
Approximately 70% of the City of Seattle's water supply is drawn from the Cedar River. Between 200,000 and 400,000 sockeye salmon spawn annually in this partially dewatered...

Modelling Longitudinal Temperature Distribution in TVA Reservoir System
A one-dimensional model has been developed for computation of water temperature in the TVA reservoir system. The model has been successfully used in evaluating the impact of incremental...

Visualization of a Groundwater Contaminant Model
Groundwater contamination is a problem of major national concern. Three-dimensional characterization of groundwater contamination is typically required. This paper describes integration...

Scientific Visualization Techniques Applied to Water Quality and Transport
Applying the advanced-computer technology available at the San Diego Supercomputer Center (SDSC), researchers from SDSC and the U.S. Geological Survey (USGS) simulated and visualized numerical...

Visualizing Groundwater Flow
This presentation demonstrates the application of some public domain scientific visualization software tools in the area of groundwater modeling. Specifically, we use these tools to interpret...

Uncertainty Quantification in Water Distribution Parameter Estimation
Calibration for water distribution system model parameters is usually undertaken with a minimal amount of field measurements so additional pseudomeasurements are assumed. Both the actual...

Measurements to Calibrate Suspended Sediment Model for Adsorbed Contaminant Transport Study of North Fork Holston River, Virginia
A daily suspended sediment (SS) and mercury transport model was developed for a 25-mile reach of the North Fork Holston River below Saltville, Virginia. Daily streamflow measurements;...

Conventional Storm Drainage Which Recharges the Groundwater
Since the demand for water is on the rise, more resourceful means of retaining and controlling the release of stormwater is needed. This retained stormwater may then be used for aesthetic...

Management of Water Resources Distribution in Iran
On the basis of 45th principle of the Iranian Constitution, seawater as well as river waters, streams and any other natural course, whether surface or underground, also floods, wastewaters,...

Effect of Manning's Roughness Coefficient in Simulating Flow Parameters in Natural Channels
Manning's roughness coefficients are presented for three of the oldest and largest irrigation canals in Egypt. The discharges ranges from 35 to 318 m3/s....

Computer Data Exchange Using National and International Standards
There is a need within the construction industry to electronically transmit standard documents between designers, owners, contractors, and material suppliers. Ideally, the transmission...

The Debate Over Large Dams
Dam megaprojects across the globe are under increasing scrutiny. Critics say large dams have clearly lost their luster. While the outcry over huge public subsidies and high ecological...

Water, Water, Where?
Water�who gets it, where it comes from, who pays for it�has always been a central issue in California. Rapidly increasing demand, fierce environmental opposition to new sources and a drought...

Oxygen Mass Transfer to Flowing Ground Water Using Oxygen Microbubbles
Mass balance and transfer of oxygen has been studied from oxygen microbubbles to low dissolved oxygen ground water passing through variously configured pilot scale vertical slice test...

Ground Water in the Pacific Rim Countries
This proceedings, Ground Water in the Pacific Rim Countries, consists of papers presented at the Symposium held in Honolulu, Hawaii, July 23-25,...

Symposium on Ground Water
This proceedings, Symposium on Ground Water, contains papers presented at the International Symposium on Ground Water in Practice, held in...

Ground-Water Modeling Without Fear
Computerized ground-water modeling has leapt from the cloistered laboratory to the field project as more and more programs are written for the personal computer. These easy-to-understand...
