Most of spillways failure in Indonesia are caused by local scouring that happens continuously at downstream, and at time local scouring get the foot of spillway will dangerous for its operational. This scour occurs because of advanced value of specific energy overflow with high head relatively so that it appear unbalance velocity flow and turbulence flow. An effort to protect foot spillway is build the structure energy dissipator. From this concept at foot spillway is designed with one, two, or more energy dissipator agree with condition and many variables at deform process mechanism appropriately. At laboratory two dimensional physical test had done and its influence for hydraulic jump bucket flow, energy reduction, along with local scour at downstream. At spillway with energy dissipator ,the length of hydraulic jump for upstream depth (Hd= 0,0320 m till 0,0750 m) present in interval (0,305 m till 0,550 m) with downstream normal water depth (0,0310 m till 0,1080 m). Froude Numbers are identified at each initial hydraulic jump bucket flow occur at model (spillway with energy dissipator) present at interval (2,00 – 2,43) The deepest scour at model present at values (0,0602 m – 0,2450 m).
