The Assessment of Sedimentation Problems in Kenyir Hydropower Reservoir, Malaysia

Lakes may take a while to respond management interventions because of the implications incremental development and degradation issues. This includes requirement for ongoing participation key lake basin institutions their operations. study’s objective is assess impacts land use activities along Kenyir Lake Basin based on sedimentation problem level. There are few hydrological methods that necessary indicators measure level sediment production, such as Total Suspended Solid (TSS), area sub-catchment, river discharge measurement, annual load production. The results showed sub-catchment Besar River released lowest average estimation at 3833.70 kg/km2/year, produced highest 128,070.86 kg/km2/year flow from tributary rivers into Lake. Basin’s downstream midstream regions had higher values than its upstream regions. study highlighted significance effects anthropogenic factors, hydrological, geomorphological, growth, developmental climate changes variables attributing phenomenon Basin. construction long-term or reservoir catchment plan, combined with formation vision comprehensive strategic vital components sound practice. efficient implementation suggested watershed programmes depends active involvement all significant stakeholders.
