Flood modelling

A flexible, robust model combined with high-quality data

Using our proprietary flood modelling software, Flowroute-i™, and high-quality topographic and hydrological data, we simulate flood events for cities and countries around the world, generating flood maps and flood risk data sets, assessing flood defences, and helping our clients understand and manage flood risk.

We have also developed a flood catastrophe model to support insurers, reinsurers and risk managers in understanding correlated risk.

Understanding flood risk in complex environments

Our dynamic flood model simulates the impact of rainfall, river and tidal water sources in complex environments, including mountainous regions and dense urban areas.

For example, we can model what might happen if flood defences are breached or sewers overflow, and what would happen if water is pumped out of the area or cannot escape. This makes our modelling exceptionally flexible and realistic. It gives our clients a far more precise and detailed understanding of risk, including the depth and velocity of water during flood events.

Modelling local, regional and national flood risk worldwide

We have access to quality geographic and flood data globally, and can generate both local and national flood models for almost anywhere in the world. The models are created in line with global best practice and incorporate national or local guidelines specific to the geology or geography of the area.

Continually validating and refining our models

We continually validate the effectiveness of our modelling techniques, for example, against the 2011 Brisbane, Australia floods, we achieved 95% accuracy.

Case studies

95% accuracy in Brisbane, Australia

Australia flood modelling

In the 2011 Brisbane floods, our model was 95% accurate in predicting flooding to properties. It correctly predicted flooding in 19 out of every 20 flooded properties.

Setting standards for urban modelling

Case study Hull

Following the 2007 flood in Hull, the Association of British Insurers and the UK Environment Agency asked us to conduct research to determine best practice in predicting flooding in urban environments.
