1. Disaster
management
and mitigation
FLOOD

2. FLOOD
An overflow of a large amount of water beyond its
normal limits, especially over what is normally dry
land.

3. Principle causes and
Types
 Areal
 Riverine
 Estuarine and coastal
 Urban flooding
 Catastrophic

4. Areal
Happens mostly in
plain areas when
water because of
rainfall or snowmelt
is more rapidly than
its can absorb or run
off.

5. Riverine
Due to slow or rapid
rise of river water
levels due to
prolong or heavy
rainfall.

6. Caused by tidal surges
due to winds and also by
tropical cyclone or an
extra-tropical cyclone
Estuarine
and Coastal

7. Urban
Flooding
Occurs in densely
populated areas
where water due to
rain exceeds the
capacity of drainage
systems.

8. Catastrophic
Catastrophic flooding is usually
associated with major
infrastructure failures such as the
collapse of a dam, which are
sometimes caused by either
earthquakes and volcanic
eruption

9. Effects: Primary
Damage to buildings and other
structures, including bridges,
sewerage systems, roadways, and
canals

10. Effects: Primary
Mobility Issues in terms of people and
goods

11. Effects: Secondary long term effect:
Lack of food and clean
drinking waters

12. Effects: Secondary long term effect:
Rapid spreading of
water borne
diseases and illness

13. Effects: Secondary long term effect:
Loss of crop and cattle

14. Effects: Secondary long term effect:
Waste and garbage
disposal issues
