ABSTRACT:

In this research paper performance of new stilling basin models for pipe outlet stilling basin were investigated experimentally by using different shape and size of intermediate sills along with impact wall and end sill .The experimental study was carried out for two Froude numbers namely 3.85 and 1.85 for rectangular pipe outlet of size 10.8 cm. x 6.3 cm. Performance index (PI) has been defined to evaluate the performance of stilling basin models tested using same sand base material and test run time. The scour pattern was measured for each test run. After 36 tests runs, it was found that scour process were reduced for a specific size and shape at a particular location of intermediate sill combined with end sill of particular size and shape. Newly developed model emerges more efficient as compared to other tested stilling basin models
