Our flood modelling software enables you to confidently understand flood risk and develop optimal solutions to manage the impacts of climate change.

Be confident in your modelling results

Model river, floodplain and urban drainage systems using Flood Modeller’s industry-leading solvers. Subjected to extensive testing and benchmarking exercises, for over 40 years, they are some of the fastest, most accurate and robust solutions available.

Independently benchmarked

Government approved

Fast and robust solvers

Model river systems

Model drainage systems

Model surface water

Take your modelling

to the next level

Flood Modeller allows you to quickly  and efficiently undertake fully integrated catchment modelling by combining surface and subsurface flow in a single model. Obtain a detailed understanding of flood risk in urban areas and understand how drainage systems interact with surface water and river flows.
