Figure 3. Prototipe of Spillway Works, Chute dan Stilling Basin 7. TEST MODEL RESULT Results from spillway hydraulic test model of Cipanundan Dam are as follows: 1) The flow conditions on the transition channel are relatively good and there is no crossing flow, 2) The flow conditions on energy dissipator up to Q1000 discharge, still form hydraulic jump, 3) The effectiveness of the energy dissipator is functioning optimally 8. CONCLUSION The results of the hydraulic flow obtained from the test model still needs a further study that is to model the flow condition when it returns to the river and to map scouring pattern in the downstream stilling basin. It is necessary in order that the results of modelling can gain the most optimal condition. 879
