SEDIMENTS REMOVAL FROM DAMS

SEDIMENTS REMOVAL FROM DAMS
Removing sediments from dams is a crucial maintenance process aimed at preserving the functionality and lifespan of these vital water storage structures. Over time, sedimentation occurs as suspended particles settle at the bottom of the dam reservoir, reducing its capacity and potentially impacting water quality. To address this, sediment removal involves FLUSHING USING RIVER WATER accumulated sediments, ensuring that the dam can continue to effectively store and release water. This maintenance activity not only restores the reservoir's original capacity but also mitigates the risk of sediment-related issues, such as reduced water supply, compromised flood control, and potential damage to downstream ecosystems. Regular sediment removal is essential for sustaining the long-term efficiency and safety of dams, safeguarding water resources, and maintaining their integral role in water management systems.
