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...
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...
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...
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...
Laboratory Analysis of Hyperconcentrations
The physical and kinematic behavior of hyperconcentrations has been reviewed and a summary of recent and past developments in hyperconcentrated flow research is presented. This paper focuses...
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 Discharge Measurement
A procedure for measuring total sediment discharge using point-source suspended-sediment data was developed. The procedure, Total Sediment Discharge (TSD), was compared to field and modified...
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...
Bed Topography and Sorting in Alluvial Channel Bends
A quasi-three-dimensional model has been developed for the purpose of calculating the velocity distribution, the bed topography and sediment sorting along channel bends. The depth-averaged...
Surface Roughness with Erosion of Earth Channels
A determination of the stresses effective in soil detachment is essential in determining erodibility. The soil roughness that exists during testing and in natural channels is a key element...
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...
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...
Baseflow and Beta Distribution
For water resources projects, design engineers are often required to separate total flow into baseflow and direct runoff. During such studies, baseflow is considered a crucial parameter;...
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...
Predicting Human Instability in Flood Flows
The delineation of high flood hazard zones within a flood plain is usually independent of the parameters that constitute a life threatening situation. In order to define human instability...
Cross Sectional Area Reduction Floodway Method
Encroachment on the floodplain, such as structures and fill, reduces the stream's flood carrying capacity, increases the flood heights and velocities, and increases flood...
Comparison of DAMBRK With DWOPER for Computing Water Surface Elevations at Stream Junctions
The National Weather Service computer programs DWOPER (Operational Dynamic Wave Model) and DAMBRK (Dam-break) are one-dimensional models using an implicit finite difference method of solution...
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...
