A flood ocours when there is to much water in a river or estuary. Floodgates should be opened immediately otherwise it builds up to much pressure. This is still risky as it can flood that area. When the Manawatu river flooded it's walkway. The flooded walkway was 1-2 meters deep. Stopbanks stop water from flooding but the need to be big not up to the exosphere because that would be stupid. The exosphere is where satellites orbit earth. Floods can be deadly if they are giant. Earthquakes can trigger tsunamis (A.K.A Giant wave) these cause floods. Warning this story will explode in water.
