3. PROTOTYPE DATA Prototype data of Cipanundan Dam are as follows: a. Main Dam - Type : Homogeny Embankment - Crest dam elevation : + 46,80 m - Crest width : 7,50 m - Slope : Upstream = 1 : 3,00 Downstream = 1 : 2,50 b. Spillway and Appurtenance Works ■ Spillway works - Type : Ogee - Crest dam elevation : + 44,00 m - Crest width : 17,50 m ■ Transition Channel - Length : 26,50 m - Width : hulu = 17,50 m hilir = 8,50 m - Elevation : hulu = + 38,00 m hilir = + 37,25 m - Basic slope : 0,028302 ■ Chute - Length : 47,65 m - Width : 8,50 m - Basic slope : 0,278069 ■ Stilling Basin - Type : USBR Type II - Length : 30,00 m - Width : 8,50 m 4. DESIGN FLOOD DISCHARGE Based on analysis, it is known that the design flood discharge is based on flood routing through reservoir. So for test model Cipanundan Dam, is used the outflow discharge from the debit of Q2, Q25, Q100, Q1000, and QPMF. The design flood discharge data are as follows: 876
