After showcasing ISIS FAST at the Flood and Coastal Risk Management (FCRM10) conference in Telford and at the ISIS User Conference in early 2010, ISIS FAST will be released in April 2011.
ISIS FAST is a completely new rapid inundation model designed and developed by Halcrow to allow quick assessment of flooding using simplified hydraulics. It provides results up to 1,000 times faster than conventional 2D hydrodynamic floodplain models.
It has been developed to be fully compatible with both ISIS Professional (1D) and ISIS 2D, allowing the user to switch easily between the new FAST and the conventional hydrodynamic solvers. The modeller can rapidly develop and test their models and make informed decisions on the appropriate choice of solution given run time and accuracy constraints.
ISIS FAST allows modellers to rapidly estimate flood extents and depths from multiple sources of water, including tide, surge and fluvial overtopping or breaching of defences, surface water and sewer flooding. The speed with which it can calculate water depths gives modellers the flexibility to explore uncertainty. Event magnitude and the interactions and dependency between flood sources were previously unpractical or economical.
As part of the ISIS suite, ISIS FAST links dynamically to ISIS 2D models, enabling large and complex studies to be undertaken much quicker than previously possible.
There are many benefits to using ISIS FAST including;
- Rapid screening for many different types of flooding
- Pluvial flood mapping and risk assessments at local, regional, and national scales
- Real time flood mapping potential when linked to forecast rainfall
- Dynamic linkage to conventional 1D and 2D solvers
- Significantly reduces the costs of modelling
- Suitable for use within probabilistic analysis frameworks
The software is already winning awards, including Halcrow’s graduate engineer, Kashif Shaad, winning the young person’s paper at the recent International Association of Hydro-Environment Engineering and Research competition.
It will be available at an introductory price of just £1,950 (standard price £3,950) providing the user maintains an ISIS Professional or ISIS 2D licence with Halcrow.
