Flood Risk Intelligence

Post-Event Loss Modelling

Rapid flood footprint and portfolio-level loss estimate after a significant event. Delivered as an engagement; tuned for reinsurance reporting and reserve-setting timelines.

Delivered as an engagement Production

Who it's for

Primary insurers and reinsurers who need a fast, credible loss footprint after a named flood event — typically in the days and weeks following impact.

Coverage today

Turnaround depends on data availability (rainfall, radar, satellite imagery). Typical first-pass estimates within 3–7 days of event; refinement follows.

Who it’s for

Claims, reinsurance, and reserve-setting teams under pressure to report a credible loss view after a named flood — before full claims data is in. We provide an independent footprint and a portfolio-level loss range, with explicit uncertainty, quickly.

What you get

  • Flood footprint for the event, built from rainfall, gauge, and (where available) satellite imagery — refined as more data arrives.
  • Portfolio-level loss estimate with an explicit range, not a single precision-faking number.
  • Per-treaty or per-region roll-up as you need for reinsurance reporting.
  • A short “what we know / what we don’t” brief, suitable to forward to reinsurers or the board.
  • Refinement passes as satellite imagery and claims data come in, without re-scoping.

How it works

  1. Mobilisation. Within 24 hours of a named event, we confirm scope, geography, portfolio, and reporting cadence. You send the exposure; we confirm which regions we can cover immediately versus those that need new hazard work.
  2. First-pass footprint. Built from rainfall, gauged river levels, and any prior hazard layers. Uncertainty is explicit.
  3. First-pass loss estimate. Portfolio is overlaid on the footprint; losses are estimated with depth-damage curves. The result is a range, not a point estimate.
  4. Refinement. As satellite imagery, additional gauges, and early claims data arrive, the footprint and loss range tighten. Updates are delivered on the cadence you need (daily, weekly).
  5. Final report. After the event data is stable, a consolidated report locks in the methodology, uncertainty envelope, and comparison to actual claims.

Honesty

Early-day estimates are wide on purpose. Narrowing them prematurely costs credibility later. Our ranges tighten as the data allows — we do not manufacture precision to meet a board deadline.

What this is not

This is a rapid engagement model, not an always-on catastrophe feed. Real-time catastrophe-model outputs that tick during an event are not what we provide; a transparent, auditable, event-scoped loss footprint is.
