Flood Risk Index – Pilot Study Prototype Flood Risk Index
Purpose:• To prioritize settlements at higher
flood risk for housing upgrade• To determine appropriate community
capacity measures to be implemented in a settlement
How it works:Based on measurable indicators• Probability of a flooding event• Topography• House structure susceptibility• Community capacity and awareness

Flood Risk Index – Pilot StudyMapping High-Risk Areas
Purpose:• Indicate areas with high flood
risk based on topographical location
• Use findings for topographical indicator in the FRI
