Annual Sediment Flushing in Hydropower Dam – Restoring Efficiency and Capacity

by

The annual sediment flushing operation is underway at the hydropower dam, releasing large volumes of silt-laden water through the spillway tunnel. Over time, sediment transported from upstream rivers accumulates in the reservoir, reducing storage capacity, affecting water flow, and potentially impacting turbine efficiency. This controlled flushing process is essential for: Restoring Reservoir Capacity – Removing … Read more

Silt Overload Halts Stoplog Operation in Dam Spillway

by

Heavy silt accumulation has caused a major challenge in dam spillway operations, as seen during the recent stoplog handling attempt. The excessive silt load, a result of upstream flooding and sediment-laden inflows, has significantly increased the weight and resistance on the stoplog, putting strain on the gantry crane system. Silt build-up in reservoirs is a … Read more

Cloudburst Flooding Hits Riverbanks – A Stark Reminder of Nature’s Power

by

A sudden cloudburst in the upper catchment has triggered intense flooding in the river, swelling its flow and turning the usually calm waters into a raging torrent. The forceful current, carrying mud, rocks, and debris, has spread across the floodplain, threatening nearby settlements and infrastructure. Cloudbursts occur when heavy rainfall is concentrated over a small … Read more
