Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...
Numerical Modelling of Pollutant Transport from a Pond to a Stream
The problem of transport of pollutants in groundwater flow from a polluted shallow pond to a natural stream is considered. A numerical model predicting changes in quality of ground water...
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....
The Microcomputer as an Intelligent Workstation in Large Scale Hydrologic Modeling
In an effort to improve the efficiency of the hydrologic modeling activities of the Maryland State Highway Administration (MSHA), a cooperative project between MSHA, the Federal Highway...
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...
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;...
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...
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,...
Three-Dimensional Simulation of Flow, Salinity, Sediment, and Radionuclide Movements in the Hudson River Estuary
The three-dimensional, finite difference model FLESCOT was applied to a 106-km reach of the Hudson River estuary in New York between Chelsea and the mouth of the river. It predicted the...
A Microcomputer Program for River Sedimentation
Erosion and deposition of sediment in rivers causes numerous problems. In order to describe this process, both the hydraulic properties of the river and the mechanics of sediment transport...
