ABSTRACT: A massive debris flow occurred on 28 April and 3 May 2016 in Beriti Hill, Bengkulu Province,
Indonesia. The debris flow carried 4.3 million cubic meters of sediment materials containing 1-2 m diameter
boulders that damaged roads, bridges, and geothermal facilities. This study assesses the debris flow hazard
through comprehensive field investigation and laboratory testing and analyses the effectiveness of proposed
mitigation measures against the destructive energy of the debris flow. A closed-type conduit Sabo dam is
proposed as a countermeasure. The design of the Sabo dam considered the engineering geology, hydrologic
and hydraulic, and geotechnical aspects. The hydrologic analysis used Synthetic Unit Hydrograph, which was
continued by flood analysis using HEC-RAS. The geotechnical analysis was conducted to determine the Sabo
dam stability utilizing the field and laboratory test data. The analysis shows that without a Sabo dam, the debris
flows were distributed to a larger area downstream and destroyed the structure of the old bridge. The impacted
area reduced significantly when the Sabo dam was implemented.
