Energy dissipation and flow characteristics of baffles and sills on stepped spillways.

The article reflects on two-dimensional physical model evaluating the effectiveness of baffles and sills along with its flow characteristics and energy dissipation. Topics discussed include hydraulic jump defined by total energy dissipation rate, energy dissipation rates causing formation of vortex zones and graphs representing several spillways. Also presented is a table featuring several abbreviations used for Sharp-stepped spillway, Rounded-stepped spillway and Sill-edged spillway.
