Simple Model for Downstream Variation of Median Sediment Size in Chilean Rivers
Publisher: American Society of Civil Engineers
Abstract: A simple theory is developed to account for the observed downstream variation of the median sediment size in Chilean rivers based on a reach-wise equilibrium sediment transport concept. The theory makes use of a bedload ...
Engelund's Analysis of Turbulent Energy and Suspended Load
Publisher: American Society of Civil Engineers
Abstract: We analyze a one-equation model for the turbulent kinetic energy of an open channel flow in the presence of suspension sediment. Engelund's pioneer analysis and his criterion for the threshold conditions for the initiation ...
Experiments on Saltation of Sand in Water
Publisher: American Society of Civil Engineers
Abstract: A high-speed video system was used to study saltation of sand in an open channel flow. High rates of image acquisition provided the information needed to resolve details of the Lagrangian properties of particle motion. ...
Erosion of Finite Thickness Sediment Beds by Single and Multiple Circular Jets
Publisher: American Society of Civil Engineers
Abstract: Sediment management in reservoirs with the help of water jets has motivated this work. Erosion caused by single and multiple submerged circular turbulent wall jets on a noncohesive sediment bed of finite thickness lying ...
Discrete Particle Model for Analyzing Bedform Development
Publisher: American Society of Civil Engineers
Abstract: A discrete element model is used to simulate the emergence and evolution in time of wind ripples with the use of simple rules for the motion of individual sediment particles. It is shown, by analyzing the probabilities for ...
Closure to “Turbulence Measurements with Acoustic Doppler Velocimeters” by Carlos M. García, Mariano I. Cantero, Yarko Niño, and Marcelo H. García

Turbulence Measurements with Acoustic Doppler Velocimeters
Publisher: American Society of Civil Engineers
Abstract: The capability of acoustic Doppler velocimeters to resolve flow turbulence is analyzed. Acoustic Doppler velocimeter performance curves (APCs) are introduced to define optimal flow and sampling conditions for measuring ...
