5m Italy Flood Map

Our latest Italy flood mapping has been updated to 5m resolution as part of our Continental Europe update.

Studies show that the number of devastating flood events stemming from river and surface water has more than doubled in Europe over the past 30 years, with a proportionally higher increase in the frequency of events caused by surface water flooding (EASAC). Projections suggest this trend will continue, with effects exacerbated by climate change, particularly across Central and Western Europe.

The maps assist with these challenges by addressing river and surface water flooding at the highest resolution available in the market at national scale. 5m resolution mapping enables the most appropriate differentiation of properties at risk for greater confidence in property specific assessments, accumulation control and risk management by insurers, reinsurers, brokers and property search companies.

As river and surface water flood behave in different ways and have different impacts on risk, our experienced hydrologists separately model these two flood types, providing an opportunity to consider surface water flooding independently in the risk assessment process.

The river flood map is complemented by river flood defence data delineating areas protected by flood defences. This allows clients to assess flood risk against their own risk preferences by incorporating all, some or none of the defence data in the assessment.

When used in conjunction with our suite of probabilistic catastrophe models for Europe or our flood event sets, the maps enable a consistent view of risk across the transfer chain, from location-level risk selection pricing and underwriting to portfolio management and optimisation.

We're committed to ensuring our clients can access our data in a way that suits them. For easy integration into existing systems, our updated Italy Flood Map is platform agnostic and available:

  • In-house directly from JBA
  • Via our wide range of resellers
  • As part of a JBA consultancy service to help identify exposure hotspots, run per-risk flood assessments and manage accumulations.

5m flood maps for Austria, Belgium, France, Germany, Italy, Luxembourg, Liechtenstein, Switzerland and the Czech Republic are now available at 5m resolution. Get in touch for more information.
