Before Flooda) Rivers and drain should be obstacle free through regular
maintenance and supervisionb) Rivers and coastal bunds checked.
c) Infrastructural set up checked such as dams, pump stations,flood monitoring stations, communication facilities, boats,mobile pumps, and flood-fighting materials like rocks,
sandbags and othersd) Inventory updating of flood forecasting and warning
monitoring system, flood prone areas and aid facilities.
e) Preparation of the DID flood emergency response

For residents(1) Hazard maps offer information on flood damage prior to adisaster, raise awareness of disaster prevention among theresidents and encourage residents in normal times to be aware of
the need to prepare for voluntary evacuation.
(2) Hazard maps ensure that residents smoothly and promptly
evacuate at the time of a warning and the occurrence of adisaster, resulting in a reduction in the damage.

Administrative bodies (persons in charge of disasterprevention)(3) Through the preparation of flood hazard maps, administrative
bodies promote administrative disaster prevention measures on aroutine basis.
(4) By using flood hazard maps, administrative bodies can respondFebquickly and efficiently at the time of a warning and the2007
occurrence of a disaster.
