Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
Plunge-Pool Scour by Inclined Jets
A series of experiments were performed in a sand-bed plunge pool with circular jets produced by nozzles at different angles and elevations and conveying different flow discharges. The...
Numerical Modeling of Fluid Mud Transport in Estuaries
The movement of fluid mud has been cited as the most likely cause of rapid sedimentation in channels located in muddy estuaries. A time dependent, two-dimensional laterally-averaged cohesive...
Management of Sediments on the Red River Waterway Project
The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks...
Temporal and Spatial Variations of Suspended Sediment Concentration during Navigation Traffic in a Natural River
Suspended sediment samples were collected within the channel border area during barge-tow passage events at three cross-sectional locations on the Upper Mississippi River. Typical plots...
A Watershed Model for Estimating Suspended Sediment Hydrographs
A mathematical model was developed to estimate soil detachment and transport and, consequently, suspended sediment hydrograph for single storms on a watershed basis. In this linear cascade...
An Improved Design of Excluding Sediment into River Intake Structures
The function of excluding sediment into river intake structures is usually achieved by the device of sluice ways. Although many sluice ways have been constructed and many formulas are...
Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...
Combined Stormwater Drainage and Treatment
Due to continuing public concern regarding environmental protection for the nation's waterways, new and more stringent water quality control regulations have been developed. This is most...
Water Quality Enhancement Technology for River-Reservoir Systems
Water quality enhancement technology is applied to a wide variety of field conditions in surface waters including rivers, lakes and reservoir epiliminia, lake and reservoir hypolimnia,...
Model of an Upgrade
As further studies and more extensive computer models help engineers better understand the workings of wastewater treatment plant processes, those engineers are finding more efficient...
Malaysia's Twins: High-Rise, High Strength
U.S. firms, following the market for new skyscrapers to Asia, are involved in design and construction of twin office towers in the commercial heart of Kuala Lumpur, Malaysia that will...
