Abstract:

The local scour downstream of two different types of outlet structures is studied in laboratory experiments with an alluvial sediment. The outlet structure terminates a hydraulic model of a diversion tunnel. Outlet structure A has a flat bottom with a vertical end sill while structure B is a ramp with a uniform adverse slope. The volume and pattern of scour development with time are measured and compared.
