Flood Modeller

Simplify your flood modeling

Flood Modeller

Flood Modeller, a Digital OneWater solution, is an industry-leading software platform which enables engineers and scientists to deliver faster and more accurate results by simplifying the modeling of river, surface water, and urban drainage systems. It enables you to confidently understand flood risk and develop optimal solutions to manage the impacts of climate change.

Floods are one of the most destructive natural hazards, and flood frequency is predicted to increase across 42% of the land on Earth by the end of the century, costing over $40 Billion in extensive damage, and causing untold stress, loss of life and disruption worldwide.*

Flood Modeller allows you to accurately model flood mechanisms by providing a powerful suite of numerical solvers, a wide range of hydraulic structures, and the latest hydrological methods. Whether you need to build a simple 1D model of an open channel, develop a 1D-2D linked flood model for an urban area or undertake fully integrated catchment modeling that incorporates sewer networks and other drainage systems, Flood Modeller will provide you with a solution.
