Velocity profiles of turbidity currents flowing over a flat bed
Turbidity currents are the main source of suspended sediment transport in reservoirs and thus one of the main causes of sedimentation. One of the techniques used to avoid reservoir sedimentation is through venting of turbidity currents. In the framework of a research work on venting, velocity measurements of turbidity currents flowing on a flat bed are carried out using Ultrasonic Velocity Prof...
متن کاملExperimental Analysis on the Water Entrainment of Turbidity Current over a Mobile Bed
Study of Turbidity Current, as one of the most important phenomena affecting the sedimentation in the reservoirs of dams, is essential. Since most of the research studies have been conducted under experimental conditions on rigid beds, the effect of erodible bed and the formation of the bed form on the turbidity current specifications is not yet clear. Therefore, in this Research, the study of ...
متن کاملSediment Transport by Mud Flows and Turbidity Currents in Continental Margins
This research has two main components. The first component addresses the evolution of mud flows (i.e. dense gravity currents) on submarine slopes, with the goal of developing the capabilities to predict the velocity, thickness, and run-out distance of mud flows. The second component of the research involves experiments on non-channelized turbidity currents (i.e. dilute density currents) and the...
متن کاملSediment Waves and Gullies Generated by Turbidity Currents
Our objective is to improve our understanding of the genesis of large-scale bed forms similar to those observed in various submarine settings, and thought to be created by both confined and laterallyspreading turbidity currents and related dense underflows in continental slopes and rises. Two types of bed forms are the main focus of this work. First, slope gullies, which are parallel, evenly-sp...
متن کاملCritical conditions of bed sediment entrainment due to debris flow
The present study describes entrainment characteristics of bed material into debris flow, based on flume tests, numerical and dimensional analyses. Flume tests are conducted to investigate influences of bed sediment size on erosion rate by supplying debris flows having unsaturated sediment concentration over erodible beds. Experimental results show that the erosion rate decreases monotonically ...
