Prematurely Terminated Slug Tests?A Field Application
Slug tests suffer problems of non-uniqueness to a greater extent than other well tests. Alternatively, a prematurely terminated slug test (PTST) or a systematized drillstem test is proposed,...
Effects of Solute Transport Processes on In-Situ Denitrification for Nitrate Control in Ground Water
This paper discusses the effects of solute transport mechanisms on the effectiveness of biodenitrification in the subsurface environment. The only solute transport processes apparently...
Groundwater Modeling with GIS: An Example
The versatility and widespread usage of a geographic information system (GIS) as a hydrological modeling tool is only now showing up in the literature. In this regard, a research team...
Buoyant, Miscible Plume in Heterogeneous Aquifer
A three-dimensional, particle tracking scheme is used to compute the trajectory of and spread about the centroid of a mass slug added to steady flow through an infinite aquifer with an...
Sediment Transport Measurements in the Nile River at Bani Mazar
Measurements of sediment transport on the Nile River were conducted at Bani Mazar (200 km South of Cairo) during high and low water stages. Bed-load and suspended-load transport rates...
Application of Stable Channel Design Method
Systematic stable channel design methods are currently being developed by the US Army Engineer Waterways Experiment Station for use in the planning stages of local flood control projects....
Pump Station/Storage Opportunities for Urban Freeway Systems
This paper introduces the concept of utilizing underground storage to minimize both the initial cost and the long-term maintenance and operation costs of multiple pump stations for a freeway...
Optimizing Regional Detention Basins for Price Expressway
Stormwater runoff from the drainage area contributing to the Price-Santan Freeway is captured in regional detention basins which require a series of pump stations for evacuation. With...
Three-Dimensional Velocity Distribution at Open-Channel Diversions
A study is underway to develop an improved understanding of the 3-D flow pattern at 90? diversions. The main goal is to explain, via the velocity distribution, the behavior of sediment...
Three-Dimensional Modeling of Transport of Fine Sediments and Contaminants in Lakes and Estuaries
The transport of fine sediments and contaminants due to currents and wind waves in estuaries and lakes have been studied by means of field experiment, laboratory experiment and a comprehensive...
Submerged Vane Projects for Bank Stabilization and Sedimentation Management
Submerged vanes are small flow training devices placed in a stream to eliminate or create secondary currents to direct sediment in a controlled fashion. In recent years submerged vanes...
Local Resources in Developing Country Water Supplies
Maximizing the use of local resources in water supply projects can expand markets for locally produced equipment and materials, reduce exports and minimize expenditures of hard currency...
Modeling of Wetland Hydrodynamics and Transport in Coastal Louisiana
Modeling of hydraulics and transport of large wetland systems poses critical decisions between resolution of the complex geometry of a wetland and the testing required to meet study goals....
Hydrodynamic Modeling of Bolsa Chica, California, Proposed Wetland Enhancements
The California State Lands Commission (SLC) requested US Army Engineer Waterways Experiment Station (WES), Coastal Engineering Research Center (CERC), to conduct engineering studies for...
Management and Institutional Considerations in Selecting Appropriate Technologies in Water Supply and Sanitation
Rural water supply and sanitation systems in developing countries have had an unacceptably high rate of failure or reduced use. Development planners have not sufficiently considered the...
Appropriate Technology in Infrastructure Development and Management
Infrastructure management principles apply to appropriate technologies used for hydraulic structures. However, some of the principles are more culturally sensitive than others, mainly...
Education, Research and Training for Appropriate Technology
Much has been written about appropriate technology (AT) and how to accomplish it. This paper adds to that literature with specific ideas for education, training and research programs and...
Flood Control Design for Development on Alluvial Fans
Hydrology, debris production, sediment transport and hydraulic studies were conducted to provide flood control for a development within an alluvial fan floodplain. Innovative techniques...
Verification of a Numerical Model for Suspended Sediment Transport in San Francisco Bay
Two-dimensional vertically averaged hydrodynamic and sediment transport models were verified to field measurements from a 25-hour intensive survey in central San Francisco Bay. Excellent...
River Dike Design Using a Numerical Model Approach
The preliminary design of a dike field at Redeye Crossing on the Mississippi River (Baton Rouge, Louisiana) is discussed. The TABS-2 modeling system was used to develop a two dimensional...
