Standing Wave Measurements of Bedload Thickness: Feasibility in an Air System with Model Sediment
A novel technique would yield information about bedload thickness from measurements of a standing wave pattern produced by a sound source insonifying the bottom at normal incidence. The...
Coastal Sediment Budget Analysis Techniques
Sediment budget analysis techniques developed by the U.S. Army Corps of Engineers Wilmington District are described. The basic procedure combines information on shoreline and tidal inlet...
Sediment Budget at Oceanside, California, Calculated Using a Calibrated Shoreline Change Model
A quantitative sediment budget analysis was made for the shoreline segment extending from 4 miles north to 4 miles south of Oceanside Harbor using a calibrated shoreline change model....
The Santa Cruz Littoral Cell: Difficulties in Quantifying a Coastal Sediment Budget
Beach compartments or littoral cells form the framework for our understanding of the sources, transport, sinks, and storage of sand in the nearshore zone. In general, along the California...
Dredging & Nourishment Bulk Determination by Sediment Budget
'Ria' is the Spanish name for a sea flooded valley, whatever its origin and evolution. This paper discusses a project involving the regeneration and protection...
Propositions for Packed Bed Adsorption Reactor Design
This paper states ten propositions which describe the behavior of 'wave fronts', i.e., adsorbate concentration versus distance profiles at given elapsed times,...
Design of Extended Length Submerged Traveling Screen and Submerged Bar Screen Fish Guidance Equipment
The hydropower projects on the Snake and lower Columbia Rivers in the Pacific Northwest are unique because these rivers are also the spawning grounds for migratory salmon. The salmon swim...
Risk Analysis Applications for Dam Safety
Dam safety modifications are intended either to reduce the likelihood of the adverse consequences of dam failure or the magnitude of adverse consequences. For instance, widening a spillway...
Dynamics of Protective Coatings to Limit Cavitation Damage
Cavitation implosions inflict a very high impact stress on turbine blades and turbine liners. One strategy for limiting the impact on the turbine components is to overlay a protective...
Tidal Flooding Analysis, San Francisco Bay
Many leveed areas adjacent to San Francisco Bay are potentially subject to tidal flooding. In response to this concern, Congress authorized the U.S. Army Corps of Engineers to conduct...
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....
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...
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 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...
Sediment Problems Associated with Dam Removal, Muskegon River, Michigan
This paper presents an analysis of sediment movement in Michigan's Muskegon River following the removal of Newaygo Dam. The analysis utilized a physical process simulation...

Effect of Gas Flow on Physical Absorption
Air blowing over a liquid surface can greatly increase the rate of physical absorption of a gaseous component. This increase is associated with the initiation of waves and a change in...
