Estimation and Comparison of Depth of Scouring Around Straight Partially Submerged Impermeable Groynes Aligned at Different Angles

Thangamani Vijaya Kumar, Lokesh Aggarwal

Abstract


Groynes are the part of river training structures which are constructed to reduce the sediment load, protection of the banks from erosion and deflect the flow of river in a determined direction to avoid the meandering of the rivers. While protecting the banks of river from erosion, the foundation of the groynes experience severe scouring that leads to the structural collapse of the groynes which may results in loss of valuable agricultural land and life, etc. So, it is of prime importance to discuss the phenomenon of scouring around groynes. In this study, experiments were done to estimate the maximum depth of scouring around impermeable partially submerged groynes aligned at different angles and comparison of their respective scouring depth to determine the most efficient groyne alignment.
