6. SCENARIO OF TESTING In order to achieved the test model objectives, the test scenario are carried out as follows: 1) Testing of spillway weir capacity, 2) Investigation to examine the design of spillway structure to follow the designed discharge as expected, 3) Investigation to improve and refine spillway structure design and their component, 4) Investigation of impacts on dam construction Based on the test scenario above, to support test program, the model is made with two types of riverbed and riverbank, they are: 1) Reservoir model with fixed riverbed and fixed riverbank (Fixed Bed Model), is a model with riverbed and riverbank made from mixed of sand and cement to obtain similarity of roughness, 2) Downstream river model with movable riverbed and movable riverbank (Movable Bed Model), is a model with riverbed and riverbank made from loose material fine sand to imitate riverbed and riverbank material in prototype that can be eroded.
