Europe Flood

The RMS Europe Inland Flood HD Models offer a comprehensive and customizable view of risk covering 14 European countries. Starting with precipitation, continuously simulated over a period of 50,000 years, the models explicitly account for spatial and temporal correlations across the whole Pan-European domain, which can be licensed as a bundle or for individual countries.

Asia-Pacific Flood
Asia-Pacific Flood

Economic losses from weather-related events in Asia-Pacific average around $54 billion each year (Aon), and recent events such as severe floods in Japan and the Kerala floods in India during 2018, show that flood risk is breaking new records. Modeling all sources of flood risk is essential, and RMS has recently launched its RMS Japan Typhoon and Flood HD Model to help the industry understand both typhoon and non-typhoon flooding losses.

Understanding Inland Flood Risk

With 2.2 billion people, or 29 percent of the world population, living in locations that are expected to experience some level of inundation during a 1-in-100-year event, (re)insurers face growing concentrations and severity of risk. To develop a profitable book of business, they must understand and quantify what drives flood risk to develop more effective flood risk management strategies. Take a quick look at what drives inland flood risk in this video.

Understanding Inland Flood Risk

Building a Complete View of Flood Risk on Risk Modeler

RMS Inland Flood Models capture all sources of flood risk, including fluvial and pluvial flooding, at the highest hazard resolution. In markets with coastal and inland flood risk, RMS offers hurricane and extratropical cyclone models to help you build the most comprehensive view of flood risk.

Watch this video to learn about the importance of building a complete view of flood risk. We analyzed the losses from Hurricane Harvey to demonstrate how tropical cyclone-induced flooding contributed to more than 75 percent of losses.

Primary Flood Risk Underwriting

Our award-winning high-definition (HD) model framework enables modelers to explicitly capture the spatial and temporal correlations of flood risk as well as simulate losses at the location-coverage level, from the ground up, providing the most comprehensive representation of flood risk to help improve risk selection. Specialty add-ons are available for understanding the unique risk profiles of industrial facilities, buildings under construction, and marine cargo and specie across markets.

Regulatory Reporting and Solvency

Confidently demonstrate to regulators that you have a complete understanding of your flood risk and comply with the corresponding local regulations. Optimize capital reserves and gain a full understanding of market risk by grouping flood models with correlated perils (such as windstorm) or with non-correlated perils (such as earthquake).

Portfolio Management

Gain a detailed understanding of your flood risk including all sources of inland flooding such as fluvial and pluvial flooding, in addition to other, regionally important sources of flooding such as tropical cyclone-induced flooding. Make use of hundreds of primary risk classifications in addition to secondary modifiers to appropriately represent your exposure to flooding. Furthermore, exploit unique features such as bespoke fluvial flood defenses to build your own view of risk.

Reinsurance Flood Risk Underwriting

Flooding is not constrained by geopolitical boundaries and can persist over a period of days to several weeks. In particular, large tail events may impact numerous countries at the same time, as well as disparate regions within a single country. With the explicit consideration of the correlation of flood risk in space and time, reinsurers can reliably assess their exposure to large losses across their portfolios and model complex policy terms, including hours clauses.

Frequently Asked Questions

What are the benefits of high-precision flood coverage across the globe?

RMS is the only catastrophe flood modeling partner that models 80 percent of global property gross written premium using a fully probabilistic approach that includes robust event sets and each model component validated by extensive local loss data. For flood risk outside of these markets, our innovative set of Global Flood Maps offers advanced machine learning insights built on a wealth of flood hazard data. With RMS flood models and maps, the RMS Global Flood Solutions Suite covers 100 percent of global gross written premium. Our unified approach to flood risk provides consistency across your business, helping you manage flood complexity, close the insurance gap with confidence, and build a comprehensive global portfolio.

Why are most RMS Flood Models run on Risk Modeler?

Flooding can develop from multiple types of weather systems, persist over a period of days to weeks, and have localized to widespread impacts across borders. Capturing all spatial and temporal correlations and building robust views of risk with converging tail losses requires a powerful simulation-based approach and large stochastic event sets. As a high-gradient peril, flood modeling also requires analyzing detailed hazard and exposure data to understand building-level flood risk. To build the most realistic view of risk, RMS models use the HD methodology only available on Risk Modeler™. This highly scalable, flexible, cloud-native application enables (re)insurers to access all their flood models using a single application running on shared data architecture without capacity or compute concerns.

How is climate change incorporated into your flood models?

RMS Flood Models are calibrated using recent data to reflect current climate conditions. We continually review the latest scientific research on climate change to ensure that our models reflect the latest scientific consensus. RMS also offers Climate Change Models that extend our industry-leading, comprehensive catastrophe models to capture the near- and long-term climate change risk outlook.

Four Influences on the FEMA 1 Percent Probability Flood Line – and Why the Industry Needs an Independent View

Where did the 1 percent probability flood line (100-year flood), the baseline metric for the U.S. flood insurance market, originate from? Why is it so important? I encourage you to watch my webinar for the RMS® Season of Flood series as I discuss the history of the 100-year flood event and the importance and influence of this metric. As I detail in this blog, there are many factors that determine how the 100-year flood event line is drawn. In the webinar, I…

Three Principles for Exposing the Hidden Risks (and Opportunities) Within Your European Flood Portfolio

Building a profitable European flood portfolio is like walking a tightrope—a tricky balancing act. It is of course important to minimize your risk of significant losses. But while big losses certainly haunt the market—just remember the €1.7 billion claimed in the UK as a result of last December’s floods—being too cautious or overpricing will lead you to miss out on attractive opportunities.  Striking the right balance is no easy task.

The Value of Flood Protection: Quantifying the Benefits of Defenses Along U.K. Rivers

Whenever the U.K. is hit by major flooding, attention quickly turns to the performance of the nation’s flood defenses. Some defenses, such as London’s Thames Barrier, are regularly recognized for their vital role in protecting people and property. The value of other mitigation measures, however, has been frequently challenged, such as when defenses failed to prevent significant flooding in Cumbria during storm Desmond in 2015. Flooding in the…

What If The Oroville Dam Had Collapsed Completely?

RMS modeling reveals the wider risk of U.S. flooding, and a significant protection gap A combination of heavy rainfall and melting snow had filled Lake Oroville in northern California near to its capacity. Dam operators released water through the main spillway to control the reservoir level, but a 300-foot hole unexpectedly emerged, and the surrounding soil was eroded by the water gushing out. Spillway outflows were reduced to stop the erosion. …
