Relationship Between Scour Depth and Bend Radius of Curvature on the Red River
Studies of bank and bend processes were undertaken on the Red River between Index, Arkansas and Shreveport, Louisiana in connection with the navigation project on the river downstream...
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...
Operational Procedures for Estimating Bottom Exchange Rates
After briefly reviewing the terminology of the various bottom and water column exchange fluxes, the body of this paper summarizes five possible procedures for establishing operational...
Wind Generated Wave Resuspension of Sediment in Old Tampa Bay, Florida
Vertical profiles of velocity and suspended-solids concentration were measured at a scientific instrumentation platform in Old Tampa Bay during the passage of a cold front in March 1990....
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...
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...
Standardization of Culvert Flow Computations
Culvert flow computations are generally computed by the Federal Highway Administration's (FHWA) nemographs or its HY8 computer program, the U.S. Army Corps of Engineers'...
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...
Overtopping Flow Spillway for Baldhill Dam, Sheyenne River, North Dakota
An existing gated spillway structure for Baldhill Dam and Reservoir (Lake Ashtabula, North Dakota) is not capable of passing floods up to the probable maximum flood (PMF) without overtopping...
Overtopping Protection for A. R. Bowman Dam
Arthur R. Bowman Dam is a 245-foot-high (74.7-m) central-core rockfill dam located on the Crooked River in central Oregon. The probable maximum flood (PMF) would overtop the dam by 20...
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...
Fluidization Pipe Hole Spacing
Two-dimensional fluidization experiments are performed on fine (d50 = 0.15 mm) and medium coarse (d50 = 0.45...
Design of Groins on the Middle Rio Grande
The Albuquerque Projects Office of the Bureau of Reclamation wanted to use groins in place of revetments at two sites on the Rio Grande. The Bureau of Reclamation has limited experience...
Preventing Stilling Basin Abrasion
A 1:10 scale physical hydraulic model of Taylor Draw Dam outlet works was used to develop modifications to prevent back flow intake of rock into the stilling basin. Much of the back flow...
A Review of Sediment-Water Column Process Modeling and Future Applications in Waste Load Allocation
The capabilities of empirical modeling techniques are discussed and three promising mechanistic models to simulate sediment-water interactions are reviewed with respect to their possible...
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...
Innovative Reregulation Weirs for Dam Releases
Two different reregulation weir designs for dam release improvement are discussed. A porous timber crib is favored for applications where increased minimum flow is needed, and a labyrinth...
