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 f or 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' n....

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

Storm-Surge Flooding in Chittagong City and Associated Risk
Chittagong, the biggest seaport and the second largest city of Bangladesh, is highly prone to storm-surge floodings. The paper will highlight the extent of the storm-surge floodings and...

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...

Effective Management and Control of Urban Flood Disasters in West Africa
This paper begins by examining the characteristics of the impacts of flood disasters in the urban centers of West Africa. The paper then examines some significant examples of individual...

Numerical Simulation of Bridge Abutment Scour Development
This paper reports a project to simulate the development of a local scour hole around a bridge abutment by a computational model. From the prelim inary results obtained, it may be concluded...

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;...

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,...

The HEC NexGen Software Development Project
The NexGen project is developing successor software packages to the existing family of HEC computer programs. Development is occurring via teams comprised of technical specialists, computer...
