The torrential deluge of water, mud and boulders on the dam’s left abutment slopes washed off a section of the left abutment buttresses, prompting the need for immediate restoration and slope stabilization works.
The assignment is being carried out in two packages. Contract 1 involves the reinstatement of around 72,000m3 of rockfill. Contract 2 covers the installation of thousands of soil nails and untensioned rock anchors and the application of shotcrete and hydroseeding for slope stabilization. Special measures to prevent future rockfall include installation of an interceptor drain and a rock trapping net to prevent mud and debris flow. Work is expected to be completed by July 2024.
