Abstract
Located in urban and densely populated areas, Batujai Dam was the first dam built in West Nusa Tenggara Province, with a storage capacity of 25,000,000 m3 and a maximum depth of 18 m. The lifetime of the dam has been proposed for 50 years but after its commissioning in 1982, many researchers believed that the annual loss of storage due to sedimentation is higher than expected. The prediction of sediment deposition in Batujai Dam had been carried out in the past two decades. The common method used by authorities and researchers were measuring deposited sediment by using the echo-sounding technique, an adaptation of bathymetric survey. The results of previous analyses focused on Batujai Dam are overviewed and compared to obtain information on the current state of the dam. All studies observed in this paper agree that Batujai Dam experience a considerable sedimentation problem. This means the state of Batujai Dam that has a shorter lifetime is commonly shared by all researchers. Mitigation measures are urgently needed in order to better manage the sediment rate reduction to maintain the remaining lifetime of Batujai Dam.
