Bed Load Prediction in Steep Mountain Rivers
The characteristics of the stream channel morphologies in a very steep mountain ravine are explained by the data obtained through the longterm field observation. The bed load transportation...
Step-Pool Streams: An Adjustment to Maximum Flow Resistance
An experiment was conducted to study the maximum flow resistance of step pool streams and the morphology of the steps formed from clastic materials. The step pool formation was qualitatively...
A Mechanism of Pool Formation and Maintenance in Forest Streams
Laboratory and field investigations illustrate a hydraulic mechanism responsible for the formation and maintenance of pools associated with large, in-channel obstructions in forest streams....
Particle Dynamics and Bed Level Adjustments in a Mountain Stream
The focus of the study was the interaction of coarse bedload sheets with a near-static bed. At a critical discharge bed sediment was transported from upstream sources through the study...
Sediment Transport in Sewers and Design Implications
Extended studies on sediment transport in sewers were conducted at the University of Newcastle upon Tyne and using this new as well as previously available data an attempt has been made...
Determination of Geometry and Stress Distribution of an Optimal Stable Channel
A numerical model which determines the geometry of a threshold channel was recently developed (Diplas and Vigilar, 1992). This is important in the design of irrigation canals, channelization...
Luo, Ming
The algebraic stress model of turbulence is employed to calculate the 2-D flow field of the Gongzhui reservoir region. The discharge distribution among the discharging structures is achieved...
Scour Hole Depth Downstream of the SAF stilling Basin
A Model to predict the maximum local scour depth downstream of the SAF stilling basin is presented. The model is based on stability analysis of a particle attacked by the hydrodynamic...
Evaluation of Six Methods for the LP3 Distribution
Six frequently used estimation methods for the Log-Pearson type 3 distribution were evaluated using both the predictive and the descriptive performance indices. Ten LP3 populations and...
Discharge-Frequency Relationships in Distributary Flow Systems
The paper describes discharge-frequency relationships in distributary flow systems. The stream network that makes up the flow system is described in terms of how the various stream segments...
Sediment Transport Analysis Rio Grande Floodway at San Marcial Gauge
A detailed analysis of sediment transport data collected on Rio Grande Floodway at San Marcial gauge shows that the all-year total load rating curve and the seasonal rating curves yield...
Performance of Submerged Vanes for Control of Sediment in an Irrigation Canal
Removal of accumulated sediments from irrigation canals is necessary in order to maintain canal capacity. Removal of these sediments may be enhanced by directing and concentrating sediments...
Urban Runoff Based on Land Use and Particle Size
As point sources have achieved pollution compliance, the focus of pollution abatement has shifted to nonpoint sources. New Federal regulations require wet-weather monitoring of drainage...
Non-Point Pollution Loadings and their Impacts on Tennessee Valley Reservoirs
This is a three-year study which began in March 1992. The project has focused on inflow streams entering storage projects including Douglas, Cherokee, South Holston, Watauga, Norris, Chatuge,...
Theoretical study of unstable waves in the rapids of the river
This paper examines how the velocity distribution in free-surface flow affects the kinematic and dynamic velocities of disturbance waves on hillslopes or in high-gradient rivers, thereby...
Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...
Bearing Capacity of Soils
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 7 This U.S. Army Corps of Engineers engineering manual...
A Thousand Points of Data
Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential...
Computer Calculations Speed Tunnel-Lining Design
A computer program handles the computations and simplifies a method that sets forth the vast amounts of tunnel concrete lining design information in a single diagram. Using the principle...
Let's Go to the Videotape
Illustrating a design concept to educate and soften the resistance of community groups, environmentalists, government regulators and funding agencies is not a new idea. But the state of...
