Flood Inundation Prediction

This review surveys recent progress made to address fundamental issues surrounding globally consistent mapping of flood hazard in underdeveloped countries. This is ach through a novel combination of appropriate physics, efficient numerical algorithms, high-performance computing, new sources of big data, and model automation frameworks.

Voluntary purchases and adverse selection in the market for flood insurance

In a wide-ranging analysis in collaboration with Jacob Bradt (Harvard) and Carolyn Kousky (Wharton), we find voluntary insurance purchases are preferentially taking place in areas where Fathom’s model deviates from FEMA flood maps.

Environment Impact Bonds (EIBs) are in their infancy, yet are increasingly recognised as a funding solution to tackle the world’s most pressing environmental challenges. Our contribution, alongside colleagues at The Nature Conservancy, discusses how recent developments to flood models at scale can help to inform both the principal and the repayment interest rate for flood mitigation projects, such as floodplain conservation.
