Computer-Based Predictions of Atchafalaya Bay Sedimentation
The Atchafalaya River, a distributary of the Mississippi River, discharges into Atchafalaya Bay through the Lower Atchafalaya River and Wax Lake Outlet. The bay delta has grown rapidly...

Numerical Modeling of Fine Sediment Physical Processes
Fine sediment in channels, rivers, estuaries, and coastal waters undergo several physical processes including flocculation, floc disruption, deposition, bed consolidation, and resuspension....

Prediction of Shoaling in Estuarial Channels: A Microcomputer Application
Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer....

The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...

Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...

Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....

Computer-Based Design of River Bank Protection
A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and...

SEDIMOT II Application to a Large Coastal Watershed
SEDIMOT II was applied to Barker Reservoir watershed in Houston, Texas, in order to simulate sedimentation in the drainage area and the relative effectiveness of sediment control strategies....

Effect of Tall Vegetation on Erosion and Sedimentation: A Microcomputer Package
A model was developed to predict the effect of standing vegetation on sediment yield. The model is based on the relationship between local scour around standing vegetation and the role...

Coagulation in Natural Waters
The hydrodynamics and chemistry of particle-particle interactions can control the transport of particles and of particle-reactive pollutants. In lakes, particle deposition is accomplished...

Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...

Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...

The Role of Hydraulics and Sediment in Large River Ecology
The National Science Foundation has sponsored a project under the long term ecological research (LTER) program which is called the 'Illinois Rivers' LTER project....

Lake Water Level and Sediment Management?Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...

Analyses of Sediment Transport Data by Microcomputer Software
The MINITAB statistical software project has been popularly used on mainframe computers since 1972. In June 1984, a subset of the program was made available for the IBM-PC microcomputer;...

Explicit Hydraulic Modeling of Sedimentation Transients in Alluvial Channels
An explicit finite difference numerical scheme is used in this study to model sediment transients in alluvial channels. The governing equations are momentum equation and continuity equation...

Assessment of Sediment Problems in Peoria Lake, Illinois
Peoria Lake, located on the Illinois River in Illinois, is the deepest lake in the river valley. Since 1903, the lake has experienced approximately a 31% loss of original storage capacity...

Water Supply Intake Structures on Western Rivers
Many of the problems experienced with water supply intake structures on western rivers result from a failure to mitigate the effects of moving sediments. Shallow but varying flow depths...

Automation of a River Model
The U. S. Army Engineer Waterways Experiment Station (WES) has used physical models to study sedimentation problems since 1931. With the recent advent of new technology, it was realized...

Data Acquisition in USACRREL'S Flume Facility
A computerized data acquisition system has been developed that is based on a Hewlett-Packard 9845B desktop computer. The system allows determination of highly accurate water temperatures,...
