History of the Federal Interagency Sedimentation Project
Since 1939, the date of the Project's inception, the team has operated under the direction of two lead agencies - the U.S. Geological Survey and U.S. Army Corps of Engineers....

Sediment Transport Modelling from Grain Size Data
Grain-size analysis can be useful in determining some of the hydrodynamic aspects of the evolution of a natural sand body. The suite statistics approach minimizes single-sample anomalies...

Highly Concentrated Sediment Loads of the Yellow River
A set of high concentration data for the Yellow River in China is examined and compared with low concentration data and laboratory experimental results....

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...

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....

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...

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...

Criteria for a Sediment Data Set
The transport of sediment through a hydrologic system or basin is an extremely complex phenomenon. Many factors affect this movement. Criteria are established for an 'ultimate' or complete...

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...

Soil Erosion and Sediment Transport Modeling on Small Tropical Watersheds
A fundamentally-based concept of a soil erosion and sediment transport model in a forest tropical area is presented. It will be incorporated to the ANSWERS model. The forest hydrology...

A Watershed Model of Sediment Transport?Load-I
A watershed sediment transport model has been formulated and optimized upon storm hydrographs and the associated sediment load data for several watersheds that have been urbanized and...

Estimation of the Effect of Land Use Changes on Storm-Event Sediment Yield from a Small Watershed
The influence of partial deforestation in a small lowland watershed in the center of Poland on storm-event sediment yield is analysed. Rainfall-runoff model has been applied to estimate...

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...

Investigation of Low-flow Phenomenon in Case of Droughts
By the use of streamflow and truncation levels, hydrologic droughts are defined. Flows of different truncation level are obtained from each selected subbasin. Flow ratio is calculated...

Reducing the Potential for Flood Litigation
A flood event is usually followed by numerous damage claims that often lead to litigation. This paper proposes measures to mitigate the potential for litigation. It is stressed that an...

Hydraulic Design of the Unser Boulevard Crossing
As an integral part of the design process, a comprehensive hydrologic, hydraulic and sediment transport analysis was completed of the proposed Unser Boulevard crossing of Calabacillas...

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...

Determining River Stages with Consideration of Backwater Effects
In a recent hydraulic investigation on the Cache River basin, the stages of the Mississippi River at the Beechridge station were found to be necessary downstream boundary conditions for...

Bank Erosion: A Review of British Research
The paper summarizes recent contributions from British geomorphologists and hydrologists. This includes field measurements of processes, modeling of corrasion and mass failure, interactions...
