🌊 Desilting Can't Keep Up with Sedimentation! Shimen Reservoir's Sedimentation Volume Reaches 1/3 of Total Storage

Reports indicate that over fifty years since its construction, Shimen Reservoir in Taiwan has accumulated sediment reaching one-third of its total storage capacity, with effective storage reduced to about two-thirds. The Northern Region Water Resources Office of the Ministry of Economic Affairs stated that nearly 100 million cubic meters of sediment in the reservoir would cost NT$60 billion to completely remove. Desilting efforts are far outpaced by sedimentation. The article mentions current desilting methods, costs, and future plans to construct anti-sedimentation tunnels to prolong the reservoir's lifespan, along with the author's doubts about the progress and logic of the desilting plan.
