Application of Two-Dimensional Model to Predict Fine Sediment Deposition
The TABS-2 two-dimensional numerical modeling system was used to predict the potential for fine sediment deposition in the lock approach channels at Lock and Dam Nos. 4 and 5 on the Red...
Comparison of
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...
Channel Entrenchment Along the Post Creek Cutoff in Southern Illinois
The Post Creek Cutoff was constructed in 1915 by the Cache River Drainage Commission to divert flow from the Upper Cache River to the Ohio River. The construction of the cutoff reduced...
100 Years of Sedimentation Study by the USGS
On January 15, 1889, the U.S. Geological Survey began collecting sediment data on the Rio Grande at Embudo, New Mexico. During the past 100 years the U.S. Geological Survey's...
Corps of Engineers' Mississippi River Sediment Studies
In conjunction with the 1838 U.S. Army Corps of Engineers hydrographic survey of the Mississippi River, CPT A. Talcott collected sediment samples in the passes 'to determine...
TVA: A Half-Century of Sedimentation Experience
The Tennessee Valley Authority (TVA) is a regional resource development agency, created by the United States Congress in 1933 and charged with bringing to the Tennessee River watershed...
Lessons from Ten Years Experience in 2D Sediment Modeling
The purpose of this paper is to share some of the lessons learned from the experience of the Hydraulics Lab Estuaries Division (WESHE) in applying two-dimensional (2D) numerical models...
An Overview of Computer Stream Sedimentation Models
This paper discuss some of the author's experience in computer modeling of stream sedimentation problems. Comparisons of twelve selected models developed and implemented in...
Flow Modeling in the Toutle River, Washington
In support of flow, suspended load, bed load, and bedform transport measurements, a quasi-three-dimensional river flow model was adapted to a reach extending from 260m upstream to 30m...
Limitations of Modeling High Concentration Streams
Following the 1980 eruption of Mount St. Helens, high sediment concentrations caused rapid deposition and increased flood hazards along the Cowlitz River. The Corps of Engineers developed...
Goodwin Creek Channel Morphology and Stability
Selected cross sections along Goodwin Creek channel, northern Mississippi, have been surveyed a total of twenty-one times since 1977 to document channel adjustments. Initial results of...
Simulating Long-Term Sedimentation Trends on the Lower Mississippi River
A one-dimensional numerical model was used to determine long-term aggradation and degradation trends in the lower Mississippi River. Geometry in the model came from hydrographic surveys....
Bank Failure and Erosion on the Illinois Waterway
In 1988, bank failure and erosion on the Illinois Waterway were evaluated. Banks were inspected from the air and from a motor vessel; thirty-one sites were examined in detail. Severe erosion...
Exceedance of Allowable Velocity in Bank Stability
The authors have developed a method to account for flow duration in the application of the allowable velocity method through comparison with observed bank instabilities on a river system....
STUDH: A Two-Dimensional Numerical Model for Sediment Transport
TABS-2 water level and flow computations are performed by the generalized numerical model program RMA-2V; salinity and tracer transport computations are performed with RMA-4, and sediment...
Total Sediment Discharge Measurement
A procedure for measuring total sediment discharge using point-source suspended-sediment data was developed. The procedure, Total Sediment Discharge (TSD), was compared to field and modified...
Settling Basin Model for the Personal Computer
The SETSIZE program, models sediment deposition in a settling basin. The program can be applied to determine the length of time until dredging or cleaning is necessary or solve for an...
Soil Erosion, Sediment Yield, and Deposition in the Illinois River Basin
The amount of soil erosion of the Illinois River Basin was estimated by using the 1982 National Resources Inventory (NRI) and the Illinois Geographic Information System (GIS). The sediment...
Measuring Resuspension of Sediment by Barge Tows
An earlier effort to measure resuspension of sediment relied on U.S. standard depth-integrating sediment samplers. In designing a new effort to collect field data on resuspension, the...
Sedimentation in Mud Mountain Reservoir at High Discharge
Mud Mountain Dam is a single purpose flood control project completed in 1948 on the White River in the State of Washington. The White River drains the northern and northeastern slopes...
