After the embankment in Dongting Lake, Hunan Province, China collapsed due to heavy rains, it has been successfully sealed after several days of rescue efforts. The concern now is how to drain the 2.1 billion tons of floodwater, equivalent to 15 West Lakes, that accumulated. Experts suggest a gradual drainage process to maintain safety, expecting it to take over ten days. Once drained, temporary repairs on the dam will be reinforced due to poor impermeability. Experts warn of the risks post-drainage, as long-term saturation can weaken the dam's stability and increase the likelihood of collapses and seepage, which may lead to further breaches.
