Extreme Events600 mm in 24 hours,100 – 200 mm in 1-2 hours

•Heavy Rainfall during North East Monsoon affecting East Coast Stat (Widespread floods)

•Intense rainstorms during inter monsoon periods of April-May and August-October (causing flash floods in major towns)

Topography

• Hilly upper reaches• Normal sloping middle reaches (1 in 2,000)• Gentle sloping lower reaches

(less than 1 in 5,000)• Mostly subject to tidal influence downstream

Shallow river bed in flood plain due to sedimentationHigh tidal influence can cause flooding in coastal areas

Best Practice in Flood Best Practice in Flood PreparednessPreparedness

Feb

2007

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.

Before Flood

Feb

2007

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 measures

d) Flood assessment

For residents(1) Hazard maps offer information on flood damage prior to a

disaster, raise awareness of disaster prevention among the residents and encourage residents in normal times to be aware ofthe 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 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 quickly and efficiently at the time of a warning and the occurrence of a disaster.
