• 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

sedimentation

• High tidal influence can cause flooding in

coastal areas

• INSUFFICIENT DATA

• FUNDS LIMITED AND COMMITTED TO ENGINEERING STRUCTURES

• AWARENESS AMONG DIFFERENT AGENCIES AND COMMUNITIES

• LEGALITIES, SECURITY

• POLICY

• ACCEPTABLE ACCURACY

• HUMAN CAPACITY

DATA SITUATION IN THE

COUNTRY (FOR ANALYSIS)

• HYDROLOGICAL DATA• AVAILABLE FOR MOST RIVER BASINS

• TOPOGRAPHY DATA

� For all river basins contour up to 20 meters

� For some areas, lidar data is available or in

the progress of capturing

� LIDAR VERY COSTLY

� MUST FIND OTHER ALTERNATIVES



PROBLEMS IN

DISSEMINATION

Saturation level of TV, Radio, TV,

REASONS FOR DIFFERENT

KINDS OF MAPS

Flood map based on inundation

analysis for development permission

in flood risk areas because

i) More scientific, therefore trustworthy

ii) In case of legalities

iii) Higher sense of security

27



REASONS FOR DIFFERENT

KINDS OF MAPS

Flood map based on past inundation

for evacuation purpose

i) More believable for the community

ii) Cheaper to produce

iii) Easier to do

LESSONS LEARNT

� IMMEDIATE COLLECTION OF DATA

ESPECIALLY FLOOD MARKS

� GOOD NETWORKING WITH

� DO NOT HESITATE!!
