八达水库是牡丹江市郊区的一座小型水库,1979年建成运用。5年后,由于泄水渠与河道连接处未设消能工,河床抗冲刷能力又差,致使河道被冲深达1.4米。同时,泄水渠从末端开始逐步被水流冲毁长达10米。为保证水库安全,确定在泄水渠末端修建一处消能工。当时曾考虑 Baduda Reservoir is a small reservoir on the outskirts of Mudanjiang City, completed and put into operation in 1979. Five years later, due to the lack of decontamination workers at the junction between the drains and the riverways, the riverbed was poorly resistant to erosion and erosion, resulting in the river reaching a depth of 1.4 meters. At the same time, the drains were gradually washed away by water currents up to 10 meters from the end. To ensure the safety of the reservoir, it is determined that an energy dissipater will be built at the end of the drains. Was considered
