WHAT IS A FLOOD?
TYPES OF FLOODS
FLOOD IS A NATURAL INCIDENT IN WHICH A DRY AREA OR A DRY PIECE OF LAND, SUDDENLY GETS SUBMERGED UNDERWATER.
TYPE A: SLOW ONSET FLOOD
Slow onset flood happens when water bodies overflood their banks. It develops slowly, which can last for days or even weeks.
TYPE D: STORM SURGE FLOOD
Storm surge flood happens during a storm, hurricane or cyclone. It is a strong wave of water that sweeps onto land. It's an incredibly dangerous threat for people living along the coast.

TYPE C: FLASH FLOOD
Flash flood is a flood that develops within a very short time, less than six hours, sometimes within minutes. This doesn't give any time to prepare, no warnings, no words of caution.
Rapid onset flood lasts for a day or two. Even though it is destructive, it still takes a little time to develop and, thus, giving people a chance to escape.
