A flood is an overflow of water on land which is usually dry. Sometimes a water resource (river, lake or pond) gets flushed with too much water. Unusually heavy rain sometimes causes floods. When there is too much water, it may overflow beyond its normal limits

Rain-water falls on big mountains as well as upon plains. As the river bed is lower in level, all the rain-water flows to low lands and rivers. When the rainfall is heavy, rivers, streams and other channels cannot contain all the rain-water in their beds. Then the water overflows their banks. This called a flood.
Sometimes, a flood is caused by the melting of snows on the mountains which increases the volume of water in the rivers. Breaches in the embankment of a river also cause floods.
