4. Conclusion

Based on the analysis conducted in this study, the following conclusions are drawn:

1.It appears that the Ogee type spillway has the smallest capacity, except in the flow thickness of less than 1.50 m. The largest discharge is generated by trapezoid-1 type followed by trapezoid-2 type. Saws type has the smallest capacity among a labyrinth type examined in this study.

2. When the Ogee type spillway is considered as a standard (100%), the largest increase in discharge occur in trapezoid-1 type (max 274% or it is increased by 174%) followed by trapezoidal type-2 (265% or it is increased by 165%)), but after the water levels more than 1.5 cm, the percentage decreases. Instead another type of spillway is constantly increasing, although at a thickness of less than 1.5 cm of water, % smaller discharge is resulted by the Ogee type.

3. The coefficient of discharge trapezoid-1 type showed a sharp increase at the beginning of observation until a water thickness of 1.5 cm, and then tend to be flat. In contrast, other types have a tendency spillway discharge coefficient values continue to increase as evidenced by increased thickness of the water in the upstream spillway.
