Abstract :
Piano Key Weir is a type of nonlinear (labyrinth-type) weir developed specifically for free-surface flow control structures with relatively small spillway footprints. To develop a better understanding of the hydraulic characteristics of piano key weir, one laboratory-scale piano key weir under four operating conditions were tested by numerical simulation. As a result, the velocity profile, the pressure profile, and streamline were analyzed.
