About ISIS

ISIS flood modelling software, developed by CH2M HILL, provides users with a flexible and cost-effective range of tools to help understand and manage the challenges associated with flood risk.

It is an industry standard suite of modular software solutions, which have been developed for simulation of water flow, hydrology, water quality changes, and sediment transport in rivers, floodplains, canals and coastal areas. ISIS is suitable for a wide range of engineering and environmental applications, from calculating simple backwater profiles to detailed fully hydrodynamic modelling of complex urban areas of entire catchments.

Our industry leading software provides advanced 1D and 2D simulation solvers, analysis and visualisation tools and an innovative flood inundation solver unlike any other software available, all within one environment. A free version of the software is available to download and enables you to confidently apply it to smaller projects.

It is used throughout the world by government bodies, environmental regulators, local authorities, water companies, insurance companies, universities and consultants.
