Experimental and Numerical Investigations of Turbulent Open Channel Flow Over a Rough Scour Hole Downstream of a Groundsill

This study discusses the mechanism for the occurrence of equilibrium and non-equilibrium scour holes. By using a particle image velocimetry (PIV) measurement system, it measures the turbulent flow fields in an open channel moving through the rough bed below a groundsill. Then, the Reynolds-stress mo...
