Suspended Sediment Regression Model on Mud Coasts
Two statistical models of the concentration of suspended sediment on mud coasts have been developed by using the stepwise regression method. The statistical analysis in this paper is based...

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...

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 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...

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),...

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...

Convective Sedimentation from a Stable Turbid Layer
A set of experiments was conducted to test T Green's criterion for the existence of double-diffusive convective motions at an originally sharp, horizontal interface separating...

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...

Intrusion of Turbid Water into a Two-Layer Stratified Environment
The horizontal intrusion of a turbid water with some intermediate density spreading on the interface of a two-layered homogeneous body of water is investigated. The study is directed towards...

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...

Scour Protection at the Straight Drop Spillway
Tests were conducted to determine the scour and the effect of tailwater on scour downstream of the straight drop spillway stilling basin. Preliminary results are presented on performance...
