Abstract

Hydraulic engineers have been interested in studying about "The Rate of Erodible Bed SCOURING and its Development due to Jet Impacts". In this research it was investigated the changes of a jet down stream bed in two conditions of submerged & falling with applied discharge changes. Calvert outlet in submerged condition is exactly tangency on material bed level and in falling condition has 46 Cm distant from it. Tail water path in all of tests was constant and equal to 15 Cm. The jets in both two conditions make a 10 degree angle by horizon. The results indicated in early minutes of test the changes of SCOURING were severe but by passing time the changes in both two conditions are reduced. Hence, in submerged condition approximately 80% of final depth appears in early 5 minutes but in falling condition the rate is 70%.
