Flood wave reduction method e.g. for flowing waters, involves increasing velocity of flow of running waters at position with before flood wave reaches position and or during flood wave passes through by position

摘要

The method involves increasing the velocity of flow of running waters at a position. The velocity of flow of running waters at the position is increased before the flood wave reaches a position and or during the flood wave passes through by the position. At the position before the arrival of the flood wave, a level prevails, which is adjusted with the arrival of the flood wave at the position. The increase of the velocity of flow is by pumps, propellers and marine propellers.
