Specialist simulation of dam breach scenarios and extreme river flooding events — predicting downstream inundation for emergency planning, dam safety compliance, and infrastructure risk assessment.
Dam break and river flood modelling addresses the highest-consequence flood scenarios — events that, if not planned for, can result in catastrophic downstream damage and loss of life. This specialist modelling service covers dam breach analysis, extreme river flood routing, and the downstream consequences of structural failure or extreme rainfall events.
HYDRisk dam breach models simulate three primary failure mechanisms: overtopping (where flood water exceeds the dam crest), internal erosion/piping (where seepage causes progressive failure), and structural failure (instantaneous collapse). Each produces a different breach hydrograph and downstream flood wave.
The downstream hydraulic model traces the flood wave from the breach point to all infrastructure, settlements and critical facilities downstream — producing depth, velocity, hazard and arrival time maps at every location.
All HYDRisk dam safety studies are documented to the standard required by regulatory bodies across the United States, Europe, the Middle East and internationally — with full model transparency and calibration documentation.
Understanding what this study delivers — and what happens without it — is the fastest way to evaluate whether your project needs it.
Every HYDRisk study produces a defined set of technical outputs — here is exactly what you receive.
Every tool we use is the same software trusted by government agencies, major engineering firms and regulatory bodies worldwide.
Methodology, data sources and regulatory requirements differ between geographies. HYDRisk delivers the right approach for every region.
