Evaluating flood data: A 10-step framework to screen risk and design resilient infrastructure
This webinar presents a 10-step framework for evaluating third-party flood maps and models before using them to screen risk or design infrastructure. Newer standards such as ASCE/SEI 24-24 call for higher-resolution, climate-aware flood hazard data, yet a fine grid can hide weak elevation data, hydraulic methods or hazard representations. The session sets out the questions to put to flood data providers and the pitfalls to watch for.
Programme
- Telling high grid resolution apart from real elevation and hydraulic accuracy
- Limits of simplified methods such as “Bathtub” and HAND, and unmapped surface water (pluvial) flood risk
- How providers handle climate scenarios, levee assumptions and model uncertainty against ASCE/SEI 24-24
- Static regulatory baselines, oversimplified channels and hidden climate biases
- Applying the 10 questions to public, private and hybrid flood data for site engineering or broadscale resilience planning
Speakers
- Gavin Lewis, Head of Engineering and Public Sector, Fathom
- Anthony Cooper, Principal Hydraulic Model Developer, Fathom
- Alec Bernstein, Senior Managing Consultant, Climate Resilience, ICF
Who it’s for
Engineers and floodplain managers who select or review flood hazard data for infrastructure projects and resilience planning.
