Abstract
Experimental investigations using clear-water were conducted to study the effect of having an adverse rear apron on the scour depth and length. Dimensional analysis to find different non-dimensional terms affecting the phenomenon were obtained and verified with the help of the experimental data. It is observed that the maximum scour depth occurs at about 3-5 times of that depth from the end of the floor. The ratio of scour length to its depth has been increased by increasing the adverse slope of the apron. Increasing the adverse slope of the rear apron clearly decreases the scour hole downstream of the structure. The obtained results have been illustrated in the form of curves. For higher discharges, increasing downstream adverse slope. Obviously decreases the scour hole size.
