Evaluating Hydraulic Roughness in Tunnels
Much of the data presented in the literature on measured friction losses in tunnels are given in terms of the Darcy-Weisbach
Synchronized Measurements of Bed-Shear Stress and Flow Velocity in Open Channels with Simulated Vegetation
Synchronized measurements of shear stresses at the bed and velocities both within and above a simulated plant canopy in an open-channel flow are presented. Traditional (hot-film sensors)...
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...
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;...
Direct Measurement of Turbulence Structures in a Standard Jar Test Tank Using PIV System
Particle image velocimetry (PIV) is applied to the measurement of instantaneous two-dimensional velocity fields in a standard 2-liter jar test tank for several different impeller speeds....
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,...
Vegetation-Induced Drag: An Experimental Study
Open-channel flow models through vegetative canopies require a quantitative measure of the ability of plants to absorb momentum by form drag, which is commonly characterized in terms of...
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...
