Abstract

This paper presents an experimental study about scour pattern downstream of stilling basin for non circular pipe outlet using end sill of different geometry. The study was conducted by designing new stilling basin models in a rectangular shaped pipe outlet of size 10.8cm x 6.3 cm with three inflow Froude numbers namely, Fr = 1.85, 2.85 and 3.85. To study the scour pattern downstream of stilling basin, total 33 test runs were conducted using same test run time and sand bed material. The scour pattern (depth and location) after the end sill were measured for each test run. The study indicates that there is a significant effect of the shape of the end sill geometry on the reduction of scour depth downstream of end sill for the pipe outlet stilling basin.
