Climate Change Strategy 2008
Krug Mission Report 1957
Disastrous floods of 1954, 1955 and 1956 focused world attention
on the importance and the need for flood control and water
management in Bangladesh (the then East Pakistan). The report
stressed that water resources development was essential for
higher agricultural production and flood control as central
issue
Recommendation of the Mission Report led to the formulation
of the EPWAPDA Master Plan, 1964
Chronological Development of Water Management
EP WAPDA Master Plan 1964
EPWAPDA 1964 Master Plan emphasized to meeting
agricultural demand of water through large scale public
sector development for both dry season (irrigation) and
wet season (flooding) water management.
The Plan identified 63 water development projects.
This initiated the implementation of large scale Flood
Control Drainage (FCD), Flood Control, Drainage &
Irrigation (FCDI) projects including the protection of
most of the Coastal zone against tidal flooding and
Hydropower generation..
Chronological Development of Water Management
Land & Water Sector Strategy 1972
The proposed strategy emphasized the need for
quick results from water development efforts in
order to achieve food grain self-sufficiency. It
attached high priority to small and medium sized,
simple, low cost, labour intensive projects.
Although, Government did not accept the study as
a whole but the strategy of the government in the
water development sector was greatly influenced
by the study report.
Chronological Development of Water Management
MPO National Water Plan-1 1986
MPO National Water Plan-2 1991 NWP marks the systematic planning practice in Bangladesh
NWP -I , 1987 has set the following investment priorities:
(i) Minor irrigation schemes, LLP, STWs and DSSTWs
(ii) Major irrigation schemes (FCDI)
(iii) Deep tubewells (DTW)
(iv) Flood Control and Drainage Scheme (FCD).
In NWP-II, a detailed investment programme were prepared. The 20
year (1991-2010) public investment programme gave more emphasis to
FCD than NWP Phase-1. Both NWP's made important contributions to
the knowledge and understanding of the water resources of
Bangladesh. However the report was not accepted by the Government..
Chronological Development of Water Management
Flood Action Plan 1989-95
After the disastrous floods of 1987 and 1988, Government as well
as development partner's attention were once again focused to the
flood problem which initiated the Flood Action Plan. Noteworthy
features of FAP are : 26 Studies were conducted.
Attention was paid to urban FCD and non-structural flood
proofing, though agriculture remained the main focus of
regional plans;
Social, environmental and fisheries impacts and people's
participation were given particular emphasis.
Emphasized formulation of National Water Strategy
Chronological Development of Water Management
Bangladesh Water & Flood Management Strategy-1995
The BWFMS was the major strategy follow-up to FAP and
became the working policy document for the water sector.
It recommended a 5 year programs involving:
Preparation of National Water Policy
Preparation of a National Water Management Plan.
Strengthening of water sector organizations responsible
for planning, construction, operation and maintenance
Chronological Development of Water Management
Develop early warning and flood-proofing systems to manage natural
disasters like flood and drought
Designate flood risk zones and take appropriate measures to provide
desired levels of protection for life, property, vital infrastructure
agriculture and wetlands.
Policy Statement in NWPo - Related to Disaster Management
Guidelines for Protection
Regions of economic importance will be fully protected against floods.
Other critical areas, will be gradually provided reasonable degree of
protection against flood.
In the remaining rural areas, with the exception of those already covered by
existing flood control infrastructure, the people will be motivated to develop
different flood proofing measures such as raising of platform for homesteads,
market places, educational institutions, community centers, etc., and
adjusting the cropping pattern to suit the flood regime.
A system of cost recovery, pricing, and economic incentives/disincentives is
necessary to balance the supply and demand of water.
Cost recovery of services such as flood control, drainage, irrigation, and
wastewater treatment has not been considered adequately
Cost recovery for FC and FCD projects is not envisaged in this policy. In case of
flood control, drainage, and irrigation (FCDI) projects water rates will be charged
for O&M as per Government rules.
Investigate thoroughly important flood control and management issues, such as
the efficacy of coastal polders, for guiding future policy on structural
interventions.
Undertaking any special study, as may be required, for fulfilling the objectives
and programmes envisaged in the NWPo and the Bangladesh Water and Flood
Management Strategy (BWFMS).

basis during monsoon, Apr- Spt
10 days also during monsoon (CFAN), Apr-
Sept, not widely circulated
Dissemination of warning through Government and
NGO initiatives
DMB plays a great role for Disaster Management
Flood Forecasting in Bangladesh Chronological development
In the initial stage of the establishment of FFWC in 1972, there was 10
real-time flood monitoring points where forecast information was based
on the correlation analysis and Muskingum-Conge flood routing model.
During the period of 1989-94, through UNDP assistance project and
DANIDA funded Flood Action Plan 10 (FAP10) project, hydrological/
hydraulic approach utilizing MIKE11 was employed and forecast was
made at 16 locations.
During the time of 1995-99, through extension of FAP10, expansion of
Flood Forecasting and Warning System (FFWS) using MIKE11 with GIS
facilities was made and forecast was increased at 30 locations.
In 2000 to 2005 period, the model area (super model) was extended,
and forecast stations were increased to 38 no. under another DANIDA
funded project.
A project funded by CDMP-II is on going under FFWC, which is being
conducted to increase forecast lead-time from 3 days to 5 days
including generation of flood forecast at three selected projects.

Global warming will hit through water:
Through climate change :
- changes in the hydrological cycle
- sea level rise
- increased water temperatures
Through increased climate variability:
- more serious and frequent extremes,

Condition
Increase of Salinity with No Kaptai
Release+ 120 cm SLR
(Worst Scenario)
People’s participation specially in the flood prone areas by
providing information, awareness development and
increasing resilience
More emphasis to given on adaptation in the agricultural
sectors, seed variety, cropping pattern, management
practice etc.
Disaster risk incorporated town planning to be introduce for
reduction of urban flooding, water congestion etc.
Reassess and redesign of the flood embankments including
submergible embankments in NE region considering climate
change impacts.
Way forward
Redesign the National Highways, Railways and other key
infrastructures etc considering the climate change impacts
Development of early warning of storm surge inundation
forecasting covering entire Bangladesh.
Reengineering of the coastal polders by phases for Sea level
rise and storm surge for the safety of life and livelihood of
coastal community.
There are need of new cyclone shelters in the newly defined
high risk areas specially in the Barisal and Khulna division.

Way forward
There are knowledge gaps right from downscaling of the
climate model to the considerations of glacial melt or
blending of meteorological science with the hydrology.
Capacity building in these areas will be of prime importance.
Regional cooperation at the basin level for prediction of
climate change impacts and adaptation measures, sharing of
knowledge and development of resources (conservation of
water through upstream reservoirs, flood moderation and
forecasting, navigation, hydro-power etc.)
The existing Bay models are capable of forecasting storm
surge induced flooding. These models extend from Indian to
Myanmar coast. These models can for the basis for regional
cooperation
