Reservoir Sedimentation and Storage Capacity Reduction: Case Study of High-Risk Flood Mitigation Dam in Malaysia
The impacts of sedimentation not only reduce the reservoir storage capacity and shorten the dam life span but also threaten dam stability, affecting water quality and the discharge capacity and potentially damaging the dam equipment. Batu Dam was selected for the case study as a large and high-risk as well as the highest flood mitigation dam. It was chosen due to the potential risk of sedimentation that will impact the sustainability of the Batu Dam reservoir. This paper aims to estimate the volume of sediments deposited in the Batu Dam reservoir and the reduction of reservoir storage capacity. The bathymetric data of the dam is used as a field measurement, and it is the most precise and common method to determine the presence of reservoir sedimentation. Based on bathymetric data in 2013, a revised elevation-storage curve was plotted and compared with the initial design. It illustrates that the storage losses are the volume of sediments deposited in the reservoir. Based on the design sediment analysis, the calculated annual sediment trapped was 40,000 m3/year as designed. Comparing the initial design and the revised elevation-storage curve shows that the sediment deposited in the Batu Dam reservoir is about 1,100,000 m3 with 3.2% storage losses. The sedimentation rate and annual sediment trapped are 0.12 and 42,310 m3/year, respectively. This research paper foresight the potential risk of storage capacity reduction due to reservoir sedimentation.
