Outline

The most common disasters impacting Pacific island developing countries are cyclones

Fiji is highly susceptible to flooding with severe floods and cyclones the key natural disaster facing the country.

SOPAC in collaboration with the World Bank, GEF – IWRM and the Government of Fiji is collaborating to develop Integrated Flood Management for the Pacific, using Nadi, Fiji as a case study.

Background

Institutional Strengthening of Flood Forecasting and Warning Systems

Flood Risk Assessment Institutional Strengthening for Integrated

Flood Management

Project Components

Project Deliverables

High resolution digital elevation model for Nadi Flood risk assessment

◦ 2D flood inundation model◦ Flood hazard maps for greater Nadi area◦ Flood mitigation (cost benefit analysis)
