The word flood means the inability of rivers, lakes,

drainage or other waterways to accommodate massive

quantities of water, so the water overflow and enters the

surrounding area.

Flood often occurs in the area on the edge of the river or a

region that was once a river absorption, and also in the

area where the drainage system is disrupted.

This disaster usually occurs in the rainy season as the

rainfall with high intensity and with a very long duration.

There are two factors that can cause flood, the natural

factors and social factors.
