RIVER TRAINING WORKS WITH SUBMERGED VANES AT DIFFERENT ANGLES

Abstract

Scour is the main damage cause of abutments, piers, spur dykes and the hydraulic structure in the river bed .Change in flow characteristics lead to changes in sediment transport capacity, and hence to a local disequilibrium between actual sediment load and the capacity of the flow to transport sediment. At times it is required to provide greater channel depth for the purposes of Navigation as the depth available is less than the required depth. The technique of Submerged Vanes helps in performing both the works simultaneously. The technique of submerged vanes is a new, cost-effective and efficient sediment management method in rivers. This method has positive environmental effects. The performance and efficiency of a submerged vane is related to its shape. In this dissertation, Submerged Vanes performance analysis is done with different attacking angle in order to study the effect of scouring and deposition occurring due to different attacking angles and thus developing their Bed Profile and Developing their Speed Profile in the flume at various points.
