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...
County-Wide Drainage Study Using GIS
A county-wide drainage study was conducted for the County of San Joaquin, California, Department of Public Works, for the determination of storm runoff quantities for the planning of flood...
A Hydrodynamic FVM Algorithm on Arbitrary Grids
This paper presents a finite volume algorithm for the vertically averaged integral form of the hydrodynamic governing equations on an unstructured grid system. The algorithm is applicable...
Problems with Metrication in Transboundary Water Projects
This presentation discusses the lessons learned and difficulties encountered by the author in the conversion to SI (System International or modernized metric system) and provides a brief...
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...
Use of the Metric System in Water Resources
ASCE has advocated use of the metric system since 1876, and the Board of Direction's policy statement specifically urges use of SI in all civil engineering activities. In...

HEC-RAS (River Analysis System)
HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface...
Capillary Pressure-Saturation Relationships in Fracture
Understanding and quantifying unsaturated flow through fractures in rocky slope is important for design and construction of drainage system in large-scale hydraulic engineering. The data...
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...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
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...
