Riprap Design Criteria for the ARS Low Drop Structure
The ARS low drop grade control structure has proven to be an effective means to stabilize incised channels in Mississippi. However, field inspections and laboratory testing have indicated...
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...
New Lessons About the Hydraulic Performance of Highway Storm Sewer Inlets
Laboratory experiments were performed with highway storm water curb inlets to 1) reduce the oblique standing wave that extends into the highway from the downstream side of the inlet and...
Evaluation of Embankment Erosion at TVA's Chickamauga Project
Studies were made to evaluate the extent of erosion to be expected under probable maximum flood (PMF) conditions. The erosion studies were made using the EMBANK computer program. The results...
Stepped Spillway Design for Flow Over Embankments
Many embankment dams have been identified as unable to pass their design flows without failure due to overtopping. The U.S. Bureau of Reclamation (Reclamation) is currently at the forefront...
Fluidization Pipe Hole Spacing
Two-dimensional fluidization experiments are performed on fine (d50 = 0.15 mm) and medium coarse (d50 = 0.45...
Bridge Scour Vulnerability Assessment
Although the failure of the New York Throughway bridge over Schoharie Creek in 1987 has focused national attention on scour related failures, other failures reinforce the need for implementing...
TABS-2 Application to Kawainui Marsh Flood Control
The TABS-2 mathematical modeling system was used to evaluate the effectiveness of alternatives designed to eliminate flooding problems in the Kawainui Marsh located in Kailua on the east...
The Design of Scour-Safe Bridges
Two new highway systems, the East Papago and the Pima freeways, are currently under design and construction within the Phoenix, Arizona, metropolitan area. Both of these highways will...
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...
Appropriate Technology in Hydraulic Engineering
Appropriate, and successful, technology transfer is contingent upon the simple dictum: technology transfer is context dependent and context specific. Optimum success in the transfer of...
The Role of Computational Fluid Dynamics in Hydroturbine Analysis
Prospects of developing comprehensive methods of computational fluid dynamics for the analysis and design of new generation of hydroturbines are considered. Unique requirements for this...
Design of High Capacity Spillways for Ritschard Dam, Colorado
A hydraulic model investigation was conducted by the Bureau of Reclamation to assist in designing the hydraulic structures associated with Ritschard Dam. Ritschard Dam will have a labyrinth...
Dam Break Analysis for a Series of Dams Using the HEC-1 and DAMBRK Computer Programs
The HEC-1 and DAMBRK computer programs were developed by the US Army Corps of Engineers, Hydrologic Engineering Center (HEC) [3] and by the National Weather Service (NWS) [4], respectively....
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...
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...
Issues and Challenges Facing the Effective Delivery of Scientific Visualization
The availability of economical hardware and software products for scientific visualization has stimulated implementation of scientific visualization within high performance computing environments....
A Modular Visual Interface for Computational Fluids Forecasting
A forecasting system is under development for predicting the three-dimensional physical features (e.g. velocity, temperature etc.) of large water bodies. Visualization and interface development...
Visualization of Grids and Flow Fields for CFD Data
This paper will address visualization of grids and flow fields for computational field simulation. Specifically, we will present results and demonstrations of surface and grid generation...
Existing U.S. Standards in Hydraulic Engineering
The Task Committee on Recommendations for Standards in Hydraulics confined itself to topics that are used in hydraulic computations or design. Thus numerous standards related to size,...
