Heavy storms may sometimes cause huge volumes of water to depart from a river's natural course and spread over previously dry land. Unstoppable and all-pervasive, the resulting floods can be devastating to human life.

Causes of Floods:

Flooded areas of land usually start off as very dry land. Floods are caused by heavy rains that pour to much water into rivers and other waterways. Making these natural channels unable to carry all the water. Rising water flows over or breaks the banks to the waterways causing the surrounding land to be flooded. Different causes of floods can come from masses of snow melting of tidal waves.

Where do Floods occur?

The type of land that is prone to flooding are broad and flat usually situated on the banks of a river or main waterway. Rivers that flood are regarded in three different stages. They are:-

ONE: Water comes off the mountains, eroding the beds and banks of the river as it flows.

TWO: This type river travels through broad valleys which slows the current of the river down. If the current is slow it will transport less material down the river.

THREE: Flood-plain stage. Little if not any erosion takes place most of the material tha tis carried in the current is suspended and deposited to the form a flood plain.
