CH2M HILL provides free update to industry-leading flood management software

CH2M HILL is pleased to announce the latest release of ISIS, version 3.7. This is the latest update to the industry-leading river and floodplain modelling, and real-time flood forecasting suite of software. It provides users with a multitude of new cutting edge tools, features and improvements, many of which have been in response to user requests from across the world.

The software was showcased at the annual user conference on 16th October, held at CH2M HILL’s European headquarters in London, where delegates from across the globe had the opportunity to hear about the new innovations and developments within beta version 3.7.

Vijay Jain, CH2M HILL Software Sales Manager commented; “ISIS has been in development since the 1970s and we continue to build on this robust modelling package. We’re excited to announce the launch of various new tools including ISIS VIEWER, a brilliant new tool which represents flood information in an interactive way, enabling better decision making and more effective engagement with stakeholders, in addition to various hydrological enhancements making the software even more applicable to flood management projects worldwide”.

Other updates provided by the global full-service consulting, design, construction, and operations firm include support for both metric and US customary units, improved calibration functionality and enhanced tutorials and help manuals. CH2M HILL has also provided a Beta release of the ISIS-SWMM Link which allows users to combine the features within ISIS with those of the US Environmental Protection Agency Storm Water Management Model (SWMM).

CH2M HILL will continue to provide a fully functional version of ISIS for free, allowing users to download the latest version of the software directly from their website at no charge, which can be applied to both commercial and non-commercial projects. When projects grow then relevant paid-for versions of the software can be purchased.

CH2M HILL’s Technology Director, Brock McEwen commented; “ISIS continues to provide users with a flexible and cost-effective range of tools to help understand and manage the challenges associated with flood risk. The ISIS suite is used internationally as it provides our clients with a range of innovative and unique features, such as ISIS FAST which provides results up to 1,000 times faster than traditional two-dimensional models and is particularly suited to rapid flood inundation mapping. If you haven’t tried ISIS, you should!”
