Experiments were performed over smooth and corrugated aprons with different corrugation dimensions to study the scour and flow characteristics under submerged wall jets condition. The scour depth and length are significantly lower for corrugated than smooth rigid aprons. The maximum reductions in scour depth and length are 79 and 83%. respectively. https://www.diegojavierfares.com/flash-offer-A-D-EJ-123-Newton-Compact-Balance-Scale-120-x-0-001-g-hot-grab/
