Abstract

Kertosari dam was built to irrigate an irrigation area of 2,056 Ha with a length of 14,659 Km of
Kertosari irrigation canal. As a result of the non-optimal function of the sand trap to capture
sediment, sedimentation occurs in the irrigation canal so that the carrying capacity of irrigation
water discharge is reduced, eventually decreasing agricultural production in the long term which will
hamper the self-sufficiency program launched by the government. Based on the results of the
calculation of the amount of sediment transport that occurs the Kertosari Dam is 8,312 tons/day or
3,160 m3/day. Furthermore, the results of the sand trap planning ( V ) = 284.43 m3 280 m3. For LB
= 1195,462 m2, because Fr < 1 then: 0,583 < 1 with 0 = 9.039 N/m2. When the sand trap is full and
empty = 47.54>1.667, the sediment that has settled in the full or empty sand trap can no longer be
eroded into floating cargo.
Key words: Sand trap; Kertosari weir; Flying sediment; Sediment settling
