The Effects of Water Surface Profiles on Manning's Roughness Coefficient
The Manning Equation has wide application in engineering practice. Nonetheless, certain aspects of it are still not widely understood. Often, engineers deduce the value of Manning's...
A New Technique for Measuring Vegetation Density
Detennination of the discharge capacity of a vegetated channel or floodplain requires a reasonable estimate of a flow resistance coefficient; such as Manning'
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...
Fostering Reclamation through Cooperation
The WaterReuse Association of California is a statewide nonprofit organization dedicated to removing the barriers to water recycling in a State where water supply is a critical issue....
Estimation of High Spring Floods Causing Inundation in Non-Studied Rivers of the West Siberian Plain
Spring flooding is the main and the most abounding in water period in flow regime of West Siberian rivers. As a result, there is powerful and wide inundation on relief of West Siberia....
Zonification of Areas with Inundation Risk by Means of Mathematical Modeling in the Rosario Region, Argentina
Water course flood valleys are often being subjected to processes of urbanization that take place in several big cities of the world. Therefore, urban planning strategies based on hydric...
Wetland Designs for Environmental Protection?Application in India
In many developing countries raw sewage are discharged into rivers and lakes. This practice causes severe degradation of regional water quality, and often results in serious public health...
Mitigation Measures for Eroding Muddy Shores
A criterion for the stability of muddy coasts is proposed, accounting for bottom resistance, hydrodynarnic forcing and sediment supply. Although qualitative, this criterion provides a...
The Use of an Equivalent Porosity Method to Model Flow in Marshes
Two dimensional modeling of marshes under unsteady flow conditions often involves description of sections that alternately wet and dry. The equivalent porosity method (King and Roig, 1988;...
Two- and Three-Dimensional Hydrodynamic Modeling of the Salton Sea, California
The Salton Sea, the largest surface water body in California, faces a myriad of problems related to rapidly changing water levels, rising salinity, accelerated eutrophication, fish kills,...
Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
Dam Foundation Erosion Study: Pit 4 Scale Model Simulation
This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area...
The Three Gorges Project: Relocation of Reservoir Population
The Three Gorges Project of China, the world.s largest single water resources project, was officially begun its construction in December 1994. The project involves a massive reservoir...
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...
Observations of Tidal Circulation in Mamala Bay, Hawaii
A comprehensive measurement program, designed to study circulation processes and support hydrodynamic modeling, has been carried out in Mamala Bay on the south coast of the Island of Oahu,...
Comparison of Near-Field Dilutions Derived from In Situ Measurements and Simulated Dilutions at the Sand Island Sewage Outfall Plume, HI
Near-field dilutions of the Sand Island Treatment Plant (SITP) wastewater plume were derived from salinity measurements made at the sewage outfall between Sept. 25?Oct. 1, 1994, a period...
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 and Sanitation Intervention in Flood Mitigation Programs
Disasters, like floods and cyclones, are almost annual events in Bangladesh. Often post-disaster epidemics of diarrhoeal diseases cause more short- and long-term health problems than injuries...
