Indian Flood Model launched

Published on Feb 04, 2013

The Willis India Flood Model:

• is a probabilistic flood model for 23 Indian cities based on 10,000 years of simulated events;
• quantifies flooding losses from both river flooding (fluvial) and surface water flooding (pluvial);
• uses custom vulnerability functions and in-house expert view of exposure data unique to Willis Re;
• is integrated into the eQUIP proprietary catastrophe modelling platform

The Willis Indian Flood Model assesses the likelihood and magnitude of losses from fluvial and pluvial flood events by simulating flood events based on the spatial and temporal patterns present in the observational record.

The modelled rainfall and river flows are propagated through the 23 cities using the state-of-the-art modelling software, JFLOW+, developed by WRN partner JBA to derive flood depth and extent assessments.

The model calculates average annual loss and occurrence exceedences and can define technical rates and assess reinsurance and capital requirements.

The model accepts exposure data (the more detailed, the better) and calculates the probability and quantum of a flood loss to that portfolio.
