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...
Mechanics of Mud Flows in Curved Channels with Uneven Beds
Most natural debris flows move through paths that are curved and that have significant bed topography. Owing to the dependence of the mechanics of wet debris containing substantial amounts...
Comparison of Models for Single-thread Streams
A variety of two- and three-dimensional models for flow in curved channels and rivers have recently been made available for engineering use, and the question arises as to how sophisticated...
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...
The Computation of Total Sediment Transport in View of Changed Input Parameters
The sediment transport phenomenon is one of the most difficult fields in water research. Due to the numerous parameters and various interactions among them several theoretical-empirical...
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...
Convolution-Integral Modeling of Non-Equilibrium Sediment Transport
In transient process of sediment transport due to unsteady or/and nonuniform flow or discontinuity of boundary condition, non-equilibrium process appears and it sometimes plays an important...
Two Dimensional Nonequilibrium Transport of Nonuniform Sediment
Mathematical models based on diffusion and/or diffusion convection equations have been widely applied to study sediment transport in suspension. Some of the studies were reported by C.C....
On the Coexistence of Bedload and Suspended Transport for a Uniform Grainsize Material
A sensitivity analysis and an experimental verification have been made to assess the validity of the equations that describe the sediment transport in non-equilibrium conditions, when...
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...
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....
Sediment Transport Modeling Considerations
In addition to understanding the theory and concepts of mathematical modeling, the engineer or scientist must also have knowledge of the river to be studied, the available data, and the...
Daily Suspended Sediment Model for Water Resources Management
A daily model of streamflow and suspended sediment (SS) concentrations has been developed to analyze daily suspended sediment records from tributary basins. The model provides a method...
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...
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...
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...
