Sediment Transport Mechanism Over Rippled Sand Beds

Depth-Averaged Equations for Free Surface Flows
Depth-Averaged equations for free surface flow are derived by applying fundamental physical principles of mass conservation, momentum and moment of momentum on a control volume from the...

Santa Clara River Fluvial Analysis
The Santa Clara River watershed, located in Los Angeles County, has been subject to rapid increases in population and urban development, resulting in channelization, new bridges, and increased...

Manning's Roughness Coefficient for Coarse-Bed Channels With High In-Bank Flows

Rational Design and Operation of Packed Bed Adsorption Reactors
Design of packed bed adsorption reactors is based presently upon the parameter empty bed contact time (EBCT), a fallacious concept. The column wave front behavior, instead, should be the...

Fluidized Bed Denitrification of Secondary Effluent during Wastewater Reclamation in Southern California
A pilot scale fluidized bed denitrification bioreactor was operated for a period of three years as one unit process in a series designed to repurify secondary effluent for subsequent indirect...

Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...

Bridge Hydraulic and Scour Analysis Using FESWMS-2DH
Stream crossings are usually designed to satisfy all engineering and enviromnental constraints at the lowest possible cost. As a result, roadway approach embankments leading to bridge...

At-A-Station Temporal Variations in Flow under Drought and Flood Conditions and Associated Sediment Problems
The way flow variations take place with time under drought and flood conditions, in comparison with normal flow condition, has been investigated along with the related sediment transport...

Calibration of Sediment Transport Model for the Upper End of Elephant Butte Reservoir
Elephant Butte Reservoir is located about 125 miles north of El Paso, Texas on the Rio Grande. The reservoir is approximately 35 miles long with a narrow neck, called the Narrows, about...

Field Measurements of Streambed Scour at Bridge Piers in Ohio
Field measurements made from 1989 to 1994 were evaluated to characterize pier scour at 21 bridge sites in Ohio. Pier scour was observed at sites in 45 of 47 real-time scour measurements....

How to Manage Floodwaves in the Dutch Meuse: Future Measures to Reduce the Inconvenience of Inundations
This study showed that in the Gravelmeuse the combination of nature development and reducing of inundation inconvenience is possible. In the framework of the obliged supply of a fixed...

Channel Scour Protection at Roadway Crossings
There are several forms of channel scour which may damage a bridge or culvert crossing over a natural or improved channel. Typical forms of scour include general degradation, local scour...

Study of Hydraulic Jump Lengths on Inclined Channel Beds
A hydraulic jump is generally used to dissipate kinetic energy of flow to protect man-made structures such as spillways, drop structures, and outlet works. It serves as a perfect location...
