Abstract :Energy dissipater in the stilling basin is a structure designed to protect downstream of the spillway from erosion and scour by reducing flow energy in the energy dissipation pool. Energy dissipation pool is an important element of hydraulic structures as a transition between the high-velocity flow and the sensitive tail water. The aim of this study is to investigate the energy dissipation ratios of baffle blocks which constructed in Type III stilling basin by using physical and numerical modeling methods. Energy dissipation ratio of the baffle blocks were determined in 3 different layouts as single row, two rows and two rows without end sill are tested. In addition, these experimental studies were tested by numerical study. Results show that, extra added chute blocks help to increase energy dissipating ratio at the energy dissipating pool and so the stilling basin length shortens by shortening the length of the hydraulic jump. The physical study results and the data obtained from numerical modelling are also similar to each other.Keywords : Open channel hydraulics, Spillway structures, Stilling basins, Energy dissipation block, Energy dissipaters, FLOW-3D, Hydraulic Jump
