Abstract:

Downstream of stilling basin is projected to the sever scouring as results of high kinetic energy leaving the basin. This scouring, normally causes degradation of the channel bed immediately downstream of the basin. The progress of degradation will affect design criteria and size of riprap for control of scouring. Experiments were conducted to evaluate the effect of the degradation level on the bed shear force and size of the riprap required to protect scouring. Results revealed increase in incipient motion of riprap as degradation level and tail water was increased.
