In addition dam demolition demolition allows a large number of earth and sand into the river downstream complement to slow the flow of water continued erosion downstream bedrock
In addition, dam body demolition allows large amounts of soil sand to enter the downstream river to replenish, to slow the continuous erosion of the downstream rock plate
In addition, the dam body can be removed to allow a large amount of soil and sand to enter the downstream channel for replenishment, so as to slow down the continuous scouring of downstream rock disk by water flow<br>
