Flood reduction method for cities, involves increasing speed at which water flows along river, by positioning ship with large engine performance against obstacle, causing floodwater to accelerate downstream towards river bank
The method involves increasing the speed at which water flows along a river, by positioning a ship with large engine performance e.g. excursion streamer, army boat, against an obstacle, e.g. a bridge pier, causing floodwater to accelerate downstream towards the river bank.
