Abstract
In rivers and streams, one of the most challenging problems is to minimize and to know the depth of scour due to changes in flow pattern around the hydraulic structures for its stability and economical design consideration.
This chapter presents a critical review of the investigations on scour due to submerged water jets. A vast amount of literature exists on the topic of scour by water jets in soils, however, less attention has been focused on the mixture of sediment, i.e., sand-silt-gravel mixtures. Various aspects of scour process, role of different parameters on equilibrium scour depth, dimensional analysis, change in scour depth with respect to time, scour hole profiles, and equations for scour depth estimation are discussed herein. Scour processes have been studied from time to time by many scientists and researchers. The detailed review of literatures related to scour in cohesionless sediments is presented. The brief descriptions about the important parameters in the process of scour by jets were discussed and how these parameters can help in identifying the practical problem were shown with real time examples for safety of hydraulic structures against erosion and scour due to water jets.
