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 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...
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....
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...
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...
Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability
One of the main purposes of the ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability is to assemble worldwide sedimentation data from field and...
Field Data Collection and Analysis of Hyperconcentrations and Mud Flows
Hyperconcentrated flows and mud flows exhibit properties quite dissimilar from Newtonian fluids. In order to further our understanding of such phenomena, field data have been collected...
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...
A Computer Model for Gravel Pit Headcut Simulation
Sand and gravel mining activities have led to numerous problems in river management. A review of many complaints on sand and gravel mining indicates that the major concern is structural...
Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...
Scour Assessment at Bridges
Due to the key role that bridges play in the national transportation system, the Federal Highway Administration has developed a scour evaluation program. This program, issued in the form...
Local Scour at Bridge Abutments
Comparison of local scour depths at bridge abutments computed using different equations yields a large variation in predicted values. To consolidate the fragmented results of previous...
Analysis of Local Scouring
An understanding of local scouring is very important for the safety and integrity of hydraulic structures. The location, shape, and magnitude of the scour hole is a function of dynamic...
Application of Hydraulic and Sediment Transport Principles in the Design of Tidal Exchange Structures
This paper presents a procedure for the analysis and design of tidal exchange structures, such as tidal gates and training dikes. In lieu of over generalized theories or complicated modeling...
Hydraulic Mechanisms of Riverbank Erosion
Recent efforts are described to develop an improved understanding of bank failure due to piping in noncohesive layers in riverbanks. The efforts included field surveys and laboratory tests....
Geotechnical Aspects of River Bank Erosion
The principal geotechnical mechanisms of river bank failure are identified on the basis of extensive field investigations on many different river systems. The role of each factor depends...
Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...
Regional Flood Plain Management
A flood plain management plan for White Rock Creek in the Cities of Dallas and Plano, Texas was developed. New technologies such as three-dimensional topography, CADD, and remote sensing...
