The stilling basin is a structure that useful to reduce the water energy of supercritic-flow that spill on downhill of the weir to be the sub-critic-flow on the behind the end-sill. The end-sill structure is located at the end of the stilling basin. The hydraulic jump that formed in stilling basin, its length can be reduced by adding the end-sill high. The jump length function was developed based on hydraulic leap depth in the upstream and the downstream. The length was conducted experimentally in laboratory. The data of experiment result was analyzed by regression technic. The results are the hydraulic jump length in a function with variable is the downstream depth plus high of the end-sill and upstream depth of the hydraulic jump.
