THE KEY IS PREPAREDNESS (FHM??)

i) Before Flood

ii) During Flood

iii) After Flood

Feb 2007 Before Flood

a) Rivers and drain should be obstacle free through regular maintenance and supervision

b) 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 others d) Inventory updating of flood forecasting and warning monitoring system, flood prone areas and aid facilities. e) Preparation of the DID flood emergency response mechanism such as set up of emergency/flood surveillance teams, Flood Operation Manual, District/State/Federal Flood Operation Centre,flood emergency operation training. Feb 2007 During Flood

a) Continuous Flood Operation

b) Flood fighting

c) Collection, dissemination and documentation of flood information such as flooded areas, number of people and roads affected, alternative roads, flood mitigation measures.

After flood

a) Physical restoration such as repair of facilities

b) Compilation of Flood Information

c) Flood analysis- causes of flooding, identify possible Feb measures 2007 d) Flood assessment DID’S OPERATIONAL STANDING ORDER FOR DISSEMINATION OF CURRENT RIVER LEVEL INFORMATION

(2) Hazard maps ensure that residents smoothly and promptly evacuate at the time of a warning and the occurrence of a disaster, resulting in a reduction in the damage. Administrative bodies (persons in charge of disaster prevention) (3) Through the preparation of flood hazard maps, administrative bodies promote administrative disaster prevention measures on a routine basis. (4) By using flood hazard maps, administrative bodies can respond Feb quickly and efficiently at the time of a warning and the 2007 occurrence of a disaster.
