초록

This study aimed at proposing the optimum design of stilling basins in dam spillways by analyzing hydraulic characteristics for various positions and shapes of end sills through the hydraulic model test. The performance of energy dissipating in the case of vertical shape of end sill was much better than the case of inclined shape. Moreover, we could confirm that no further improvement in hydraulic characteristics at stilling basin as well as downstream of the river were made if the height of end sill was increased up EL 50m, e.g., the proposed design value by computation.
