Use of HEC-2 and HEC-6 to Determine Levee Heights and Revetment Toe Scour Depths
The paper presents the use of HEC-2 and HEC-6 to determine levee heights and revetment toe scour depths. These adjustments are due to the U.S. Army Corps of Engineers, Los Angeles District...

Sediment Transport Analysis Rio Grande Floodway at San Marcial Gauge
A detailed analysis of sediment transport data collected on Rio Grande Floodway at San Marcial gauge shows that the all-year total load rating curve and the seasonal rating curves yield...

Hocking River Sedimentation Study
The channel improvement project located on the Hocking River in Athens, Ohio is estimated to have prevented over 68 million dollars in flood damages since its completion in 1971. However,...

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...

Prediction of Accretion Below Muhuri Closure Dam in Bangladesh
An equation for prediction of siltation below a closure dam in the coastal area of Bangladesh has been developed using a diffusion equation of vertical transport of sediment. Applicability...

Local Scour Potential for Large Bed Material with Shallow Tailwater Depth
Jet momentum acting on a bed particle and submerged jet diffusion theory were employed to derive scour prediction formulas in a plunge pool. Semi-theoretical formulas were suggested for...

Sediment Modeling in the Rio Grande Conveyance Channel
The Rio Grande Conveyance Channel and the Rio Grande Floodway convey water from the San Acacia diversion dam to Elephant Butte Reservoir. The Conveyance Channel was built in early 1950's...

Floating Cover Influence on Sediment Transport in Dune-Bed Channels
The results of laboratory flume experiments with a floating cover and a loose bed indicate that, relative to a free surface flow, the increased drag of a floating cover increases flow...

Carpet Flow Analysis
Under very high flow conditions, sediment may be transported either in a suspension or by carpet flow, as defined by Bagnold. This study examines the theoretical conditions for carpet...

An Interagency Overview of Selected Stream Sedimentation Models
The author's experience in developing stream sedimentation models is presented. The interagency study consisted of three phases. Phase one involved making an inventory of the computer...

Sandbar Formation in Side-Diversion Channels
Prediction of sandbar formation in side-diversion channels is desirable in a wide range of river engineering problems. However, the mechanism by which they form is still not well understood...

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...

Modeling Hydrologic and Pollutant Transport Processes for Stromwater Runoff to Surface Waters
Combined sewer overflows and stormwater discharges, which are considered point sources, and certain nonpoint sources (NPSs) display the characteristics of precipitation-driven events....

Coping with EPA's Transportation Storm Water Permit
EPA has released NPDES storm water monitoring data from group applicants. This paper will analyze the data to determine which pollutants are present in storm water runoff from transportation...

Investments in the Future
The projects that earned the 1994 Outstanding Civil Engineering Achievement Awards of Merit were improvements to the nations transportation and environmental infrastructures. On the outskirts...

Let's Go to the Videotape
Illustrating a design concept to educate and soften the resistance of community groups, environmentalists, government regulators and funding agencies is not a new idea. But the state of...

Poland Gets Moving
Poland's transportation network is a victim of two world wars, foreign domination, and neglected maintenance, but there are ambitious plans to rebuild the road and rail systems....

Computing in Civil Engineering
This proceedings consists of papers presented at the First Congress on Computing in Civil Engineering, sponsored by the technical Council on Computer Practices of the American Society...

High Level Radioactive Waste Management 1994
The proceedings of the fifth International Conference on High Level Radioactive Waste Management, held on May 22-26, 1994, Las Vegas, Nevada, continues a concerted effort to transfer technology...
