4 m and deepness of foundation is
2 m, wide of spillway main dam
obtained 45 m, with Q plan return period 100 years to 216,475 m3/s, high of wings main dam is 3 m at elevation + 190,419 m with highly of surveillance is 0,8 m, main dam construction
use rubble stone masonry, elevation of peak spillway sub at + 185,419 m with
