Abstract

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. Optimum scour depth and length are found for aspect ratio (ratio of corrugation wave length to amplitude) three for corrugated apron. The factors affecting scour depth and length were analyzed graphically, and empirical equations are proposed for predicting maximum scour depth and length, and the point of maximum scour depth for corrugated aprons. Velocity, turbulence characteristics, and Reynolds stress in scour holes for smooth and corrugated aprons were also studied.

Keywords| Wall jets, Corrugated apron, Scour, Turbulence, Reynolds Shear Stress.

HIGHLIGHTS

  • Use of a corrugated apron downstream of sluice gates reduces scour depth and length significantly.
  • Scour depth and length are at their optimum when the aspect ratio of a corrugated apron is three.
  • Velocity vector plot, turbulence intensity distribution, Reynolds stress and threshold bed shear stress are plotted and compared for smooth and corrugated
