b. The dry dam effective for flood control by cutting and defer the peak of flood by: • existing landscapes and ecosystems have not changed; • river morphology and river regime (natural flow) are unchanged; • easy to operate; • No risk in flood control functions. c. The dry dam has a low operating cost because there is no water elevation setting so it can work without door operation. d. Ciawi Dam and Sukamahi Dam can delay the flood discharge coming from the river ciliwung to jakarta, so the flood impact in the National Capital of Indonesia can be avoided. 5.
