There Vdanat arise from runoff exuberantly on agricultural land, where attached to the sediment, dust, mud, mud flows arise for this is called this type of flooding muddy flood.
Catastrophic floods: Is the flood, which coincides with a particular disaster, this catastrophe lead to the destruction of the dam, for example, leading to the accumulation of water and flooding.
Some types of floods arising from rainfall on closed places, and that the water can not evaporate them easily, or can not take place outside the water dramatically or quickly, leading to the accumulation of water and flooding.
Dams are built sometimes a way that is covered by water and flooded all populated, urban and low-lying areas, causing a very large effects of massive damage.
