Increasing Computational Accuracy of Radial Gate Flows
Radial (Tainter) gates are the most widely used flow control structure on large, open channel conveyance systems. In contrast, the hydraulic forces are complicated and this type of gate...

Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...

Waste of Water Is Costly. Why Not Use an Accurate Flow Monitoring System?
Water becomes more and more a precious good. Therefore the exact measurement of flow of water, the management of water and process control in connection with water will become more and...

Getting Wet with Metric
Conversion from what is now the American system of units to the SI system of units is a dry subject at best. In the water resources area, however, a rather complete immersion is going...

Fostering Reclamation through Cooperation

The Influence of Peak-Regulation of the Three Gorges Power Plant on Navigation
The paper studies the unsteady flow resulted from peak-regulation by daily regulation at both Three Gorges and Gezhouba Power Plants and concludes that the river section between the dam...

An Economy and Risk Analysis of Installed Capacity Expansion at the Three Gorges Power Plant
This paper studies the possibility and economy of peak-regulation operation during flood period at the Three Gorges reservoir, which will at the same time satisfy the requirements for...

Groundwater Recharge with Reclaimed Water Another Step Closer to Potable Reuse
California.s water supply is becoming increasingly unreliable, and investments to make water more reliable must be seriously investigated. In this arid region of Southern California, reclaimed...

Water Based Land Use Regulations Using GIS Water Budgeting Model
Protection of water quality and supplies in developing watersheds requires maintenance of the natural water budget. Water budgeting model using GIS provides foundation for land use regulatory...

Identification of Regional (Third Party) Impacts Associated with the Truckee River Operating Agreement
This paper focuses on problems and solutions encountered to identify regional impacts of the Truckee River Operating Agreement (TROA). Two issues influenced the development of a regional...

Transport Modeling of the Coastal Waters of Oahu, Hawaii
A hydrodynamic model of the coastal waters around the island of Oahu, Hawaii has been constructed to provide quantitative information on the movements and mixing of water that are to be...

Comprehensive Modelling of Water Distribution Networks
An analyst of a water distribution systems must frequently contend with a host of problems with very different time scales. Traditionally, such concerns have been accommodated by having...

Moving from a Model to a Decision Support System: Salt River Project's Experience with a Reservoir Simulation System
The Salt River Project (SRP) is in the third year of a process to develop a computerized hydra-meteorological decision support system (Hydromet) that will eventually cover all aspects...

Integrated Facility Information Systems: Total Information Access
This paper will attempt to fill the void in computer information handling with regards to facility management information by providing those in the water industry with tips and suggestions...

Privatization and Water Supply/Treatment Projects
Privatization is often mentioned as a way to get much needed, but difficult to finance infrastructure projects delivered for both developed and developing countries. However, the suitability...

An Engineering Information System Application for Water Supply and Distribution Systems
Engineering information systems are characterized by both static infrastructure and dynamic time dependent data. Telemetered readings can often be relatively substantial over an extended...

Salinity Management for the Upper Gila River
Over development and over allocation of the limited water supply of the S afford valley in eastern Arizona has resulted in serious depletion of water for irrigation in the San Carlos Apache...
