Selective Erosion: A Key Problem in Numerical Modelling of River-bed Changes
In capacity-controlled sediment transport of alluvial rivers the so-called 'hiding factor' determines the stability of the various grain-size fractions. The paper...
Relationship Between Channel Migration and Radius of Curvature on the Red River
The system behavior of meanders was investigated on the Red River between Shreveport, LA, and Index, AR. The effects of plan form geometry (r/w) and erodibility of bank material on the...
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....
On the Selection of Sediment Transport Equations
Certain aspects of the selection of equations to use in the calculation of sediment transport in streams are examined in this paper. The use of a critical discharge is examined and problems...
Alluvial Stream Bank Erosion?A 10-Year Study
Results of investigations of bank erosion along alluvial streams between 1977 and 1989 are given. Natural processes were found to dominate, with piping an important but hitherto unrecognized...
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...
Low-Waterway and Bank Erosion in a River With Alternating Bars Bed
In a river with alternating bars bed, the banks are often subjected to erosion due to the convergent flow resulted from the bed geometry, even in a straight channel. It is known empirically...
Stream Bank Erosion and Bed Evolution Model
The graded sediment routing and stream bed evolution model of D.K. Borah, C.V. Alonso and S.N. Prasad is expanded by combining with a riverbank erosion model developed by Osman and Thorne....
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....
Sediment Transport Due to Channel Flushing
Blocking of rivers and canals by sediment due to landslides or dumping of waste create problems of upstream flooding and drainage. Experiments are carried out in the present study on flushing...
River Training Works in Gezhouba Project on the Yangtze
A great number of research results of the river regime planning and river training work in Gezhouba Project on the Yangtze are described together with their application in the Project....
Background and Applications of Fluvial-12
The computer program FLUVIAL-12 is formulated and developed for water and sediment routing in alluvial channels. The combined effects of flow hydraulics, sediment transport and river channel...
On Sediment Transport Modeling
Basic elements of a comprehensive water-sediment model are hydraulic, sediment, and morphologic computations. The stream tube approach and minimum energy dissipation rate theories are...
ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and availability
Alluvial channel observations for laboratory and field conditions have been collected throughout the twentieth century. These data have not been adequately evaluated as to accuracy or...
Total Sediment Load Calculations for Goodwin Creek
Total sediment transport load of Goodwin Creek was calculated for the period from 10/1/84 to 9/30/88 using transport relations derived from sample data for the fines (< 0.06 mm),...
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...
Calibration of a Movable Bed River Model
This paper discusses the calibration procedures used for a model study of three miles (5km) of the Arkansas River. A hydro-power station will be added to an existing Corps of Engineers...
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...
Earthquake Effect on Sediment in Rivers and Deltas
Many authors have studied the age and distribution of the Holocene deltaic deposits of the Mississippi River. Several others have written about the magnitude and the recurrence interval...
