Reservoir Failure at Malana: Repair and Rehabilitation

摘要

Less than three months after the 86-MW Malana project in India began generating electricity, sub-surface flow below the foundations of the storage reservoir and gravity dam caused a portion of the reservoir floor to settle. The flow of water washed away foundation material beneath a four-block section of the dam. Project owner LNJ Bhilwara Group undertook several remedial and rehabilitation measures to repair the dam and prevent a similar failure in the future.
