The AIR Inland Flood Model for the United States is the most detailed probabilistic model available for assessing and managing inland flood risk. The AIR model explicitly models both on- and off-floodplain losses; features a component-based approach to estimate the vulnerability of buildings and their contents for all lines of business; supports primary risk characteristics and 10 secondary modifiers; and identifies separate flood occurrences spatially and temporally to reflect the physical properties of a flood while accommodating a 168-hour clause. The AIR model also helps establish a currency for understanding and quantifying risk in insurance and reinsurance transactions.

The 2019 Indian Monsoon Floods white paper demonstrates how AIR's probabilistic India flood hazard maps help prepare for this risk.

Findings from AIR's Kerala floods damage survey underscored how the AIR probabilistic India flood hazard maps can help insurers prepare for this risk.

The AIR Inland Flood Model for Central Europe is the industry¹s first to account for intra-country correlation of flooding using a joined physical modeling domain. It explicitly models on- and off-floodplain losses in Austria, Czech Republic, Germany, and Switzerland; accounts for flood defenses and supports custom flood defenses; features a component-based approach to damage estimation for commercial buildings; and supports the evaluation of reinsurance contracts incorporating a 504 hours clause.

This brochure provides an overview of the AIR Inland Flood Model for Japan. The model captures the risk of flooding caused by systems other than tropical cyclones, which accounts for about 40% of all insured flood losses in Japan.

Palomar sought a way to provide flood insurance that was affordable, profitable, and actuarially sound. With AIR, they found a modeling solution they could rely on to help them price the risk and set appropriate premiums.

Developing scenarios that accurately reflect real events is a complex and challenging undertaking. This issue brief addresses the principal challenges of modeling inland floods in real time.

Currently available for China, Thailand, Brazil, and Vietnam, AIR flood hazard maps display the extent of the flooding associated with river flow magnitudes at various return periods. Flood depths are also available for Brazil and Vietnam.

This issue brief helps you utilize the AIR U.S. inland flood model and better understand the results the model produces. It describes best practices for using and evaluating this tool and identifies the critical inputs needed to obtain reliable modeled loss output.

The use of secondary risk characteristics can have a major impact on modeled losses for the AIR Inland Flood Model for the United States. This document describes the secondary risk characteristics that Touchstone supports for this model.
