| Abstract | ||
| Abstract In this paper the energy dissipation was studied using stepped spillway, in addition to that the elimination of air pockets which take place at steps was also studied by using obstructions along the edge of steps. These obstructions were made from iron with square cross-section. Several experiments were conducted on stepped spillway with and without obstructions. The results of the experiments showed that these obstructions were very successful in eliminating air pockets. Their present in general had a positive effect on energy dissipation along the stepped spillway. The results also indicated that the use of these obstructions should be started from second step until the middle step of the spillway.
