| Summary: | In Indonesia there are numerous problems related to water such as floods or
deficiency water that caused by climate change. As found in surrounding areas of
Citarik river, in Cimanggung district, Sumedang Regency, West Java Province. To
solve that problems, Citarik Dam will be constructed with 31 meters height. Citarik
Dam is planned to fullfill domestic water needs for region around Citarik river,
Tegalmanggung and Sindulang village for 30 years (2021-2051). Reservoir’s life
cycle is planned for 60 years, effective reservoir volume is 202042.42 m3, dead
storage is 21743.25 m3. Total reservoir volume is 223785.67 m3. The function of
Citarik Dam’s spillway is to drain flood discharge. From Snyder Flood
Hydrograph, Spillway is designed for 1000 years flood discharge 248.021 m3/s.
Side channel, floodway channel, and energy dissipators is designed for 100 years
flood discharge 139.788 m3/s. Spillways is designed with Ogee type with 45 meters
width and 3 meters height. Stability analysis of spillway structures results that the
structure is stable from sliding and overturning failure.
