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

Seismic Evaluation of Nauseri Dam Using 3D Finite Element Analysis

by

Abstract The Nauseri Dam, a critical component of the Neelum-Jhelum Hydroelectric Project in Pakistan, underwent extensive seismic evaluation to ensure its structural integrity under operational and extreme seismic events. This study employed three-dimensional finite element analysis (3D FEA) to evaluate the dam’s performance under Operational Based Earthquake (OBE) and Maximum Credible Earthquake (MCE) conditions. This … Read more
