Proposed Structural Measures for Kelani
Embankments for lower stream (1:50 year) Upstream reservoirs
SLIDE 11
NON STRUCTURAL MEASURES
- Prepare an integrated flood risk management plan
- Establish a real-time monitoring and operation system
- Improve operation of existing reservoirs
- Improve the drainage systems
- Land use planning

Lessons from Sri Lanka
❖ MoF’s engagement is critical to allocate budgets ❖ Instruments like DPL with Cat DDO and Fiscal Risk
Assessment ensures MoF engagement
❖ Sustainability through full-time, on-the-job engagement
- f Government staff
❖ Breaking data barriers and multi-agency collaboration
