For Municipalities & Governments

Know Where Floods Will
Strike Before They Do.

Physics-based simulation that tells you exactly which streets, underpasses, and assets will flood — hours before the rain hits.

The Gap

Traditional flood maps
miss the dominant risk.

FEMA 100-year flood maps are static. They were built around coastal and riverine boundaries — leaving pluvial (rain-driven) flooding almost entirely uncharted.

Over 80% of flood events are pluvial. They propagate from surface runoff across streets, through underpasses, into basements — driven by terrain, not rivers.

Flood Dynamics models this. Every street. Every underpass. Every drainage choke point. Time-step by time-step.

FEMA ZONES
10–15% capture
FLOOD DYNAMICS
95–99% capture
What We Deliver

Four capabilities that change
how cities act on flood risk.

Asset-Level Flood Exposure Mapping
Every road, underpass, pump station, and public facility mapped against flood depth, duration, and velocity thresholds — at sub-meter resolution.
Infrastructure Priority
Pre-Event Emergency Protocols
Simulation outputs define exactly which zones to pre-position crews and equipment — before the storm, not during. Used in real storm response in NEORSD.
Emergency Readiness
Capital Budget Prioritization
Which drainage upgrade delivers the highest return? Simulation identifies highest-impact interventions so infrastructure funding goes where it matters.
Investment Strategy
Regulatory & Grant Documentation
Physics-grade output that meets FHWA, FEMA, and EPA documentation standards. Defensible numbers for federal grant applications and capital planning.
Compliance Ready
Deployment Process

From data to
actionable outputs.

01
Terrain & Infrastructure Data Ingestion
High-resolution DEM, drainage network topology, asset registry, and rainfall intensity models are ingested and processed.
02
Physics-Based Simulation Run
Time-step hydrodynamic engine computes flood propagation across the full urban terrain — hour by hour through the event.
03
Impairment Layer Generation
Depth and duration thresholds trigger impairment flags across each asset. Cascade logic identifies secondary failures.
04
Delivery: Maps, Reports, API
Interactive simulation outputs, prioritized asset reports, and API-ready data for integration with city GIS and emergency systems.

"Flood Dynamics uncovered exposure we had no tools to see before. The asset-level outputs changed how we planned our capital budget for the next five years."
