Short summary

Flood management is adopting a more risk-based approach, whereby flood risk is the product of the probability and consequences of flooding. The study developed flood inundation model (LISFLOOD-FP) that uses historical flow data to produce flood-risk maps, which will help to identify flood protection measures in the rural areas of Sri Lanka.
