Storm surge risk modeling

Understand coastal flood exposure with long-term stochastic storm simulation and climate-aware modeling.

 

KatRisk’s storm surge risk modeling helps insurers evaluate coastal flood exposure using stochastic tropical cyclone simulations and advanced hydrodynamic modeling. By combining 50,000 years of simulated storm activity with high-resolution terrain data, the model provides a clear view of storm surge risk across coastal portfolios.

Trusted by insurers and reinsurers worldwide

KatRisk catastrophe models support underwriting, exposure management, and portfolio analytics across global insurance and reinsurance markets.

Why KatRisk for storm surge

Coastal flood insight built on stochastic simulation and climate-aware modeling.

Storm surge is one of the most destructive drivers of loss in tropical cyclone events. KatRisk’s storm surge model combines long-term tropical cyclone event simulation with hydrodynamic surge modeling, allowing insurers to understand how surge events develop, propagate inland, and impact portfolios.

Key capabilities

01

Advanced surge simulation

The model integrates tropical cyclone simulations spanning more than 50,000 years of stochastic tropical cyclone simulations with advanced hydrodynamic modeling, enabling realistic representation of storm surge behavior and coastal flooding dynamics.

02

Climate variability enabled

Explicit modeling of climate variability captures global sea-surface-driven teleconnections such as El Niño and La Niña, allowing insurers to evaluate surge risk across different climate states and scenarios.

03

High-resolution coastal terrain modeling

Storm surge simulation incorporates detailed terrain and coastal elevation data to capture how coastal geography influences surge propagation and inland flooding.

04

Integrated coastal hazard insight

Storm surge modeling integrates with tropical cyclone wind and flood models to evaluate the full coastal storm hazard.

05

Speed designed for operational workflows

Large event catalogs can be processed rapidly, supporting underwriting analysis, exposure evaluation, and reinsurance planning.

Don't let storm surge catch your portfolio off guard

Storm surge is one of the most destructive and difficult-to-model coastal perils. KatRisk’s storm surge models give you the coastal resolution you need to assess true exposure and protect your book.
