Management with the financial assistance of
International Development Agency (IDA) - World Bank
• Implemented by
– Department of Irrigation (ID)
– Mahaweli Authority of Sri Lanka (MASL),
– Road Development Authority (RDA)
– National Building Research Organization (NBRO)
– Uva Provincial Council
with coordinating, facilitating and monitoring function
played by PMU(CRIP).

4. Project Briefing

– To Improve Climate Resilience - USD 110 m.
– CRIP Additional Financing - USD 42 m.

5. Project Objective - CRIP
“To reduce the vulnerability of exposed people
and assets to climate risk (Hydro
meteorological risks) and to improve
Government’s capacity to respond effectively
to disasters”

Key Project Activities of Component -1:
Development of Basin Investment Plans (DBIP)
• To improve the understanding of the climate
risk, especially for floods and drought, in
critical river basins.

7. Key Lessons of the Project – ID Sector
• Capacities of contractors are far below the expected
level
• Difficulties in obtaining required materials such as
gravel, sand and earth
• Only three months off seasons available for
construction due to water issues and cultivation
• Construction locations, structures are scatted over the
canals and scheme. Therefore packages are not
attractive for contractors

9. Key Challengers to address in future
work
• Area specific forecasting system which is user
friendly and digestible to end user.
• Extreme events in three days advance.
• Basin Level Reservoir Operation rule curves for
floods and droughts.
• Well planned online data collection system at
basin level for flood forecasting and to run the
inundation models
