ISIS by Halcrow – one of the leading software packages for river modelling - now boasts a new two-dimensional version, ISIS 2D.
ISIS is used throughout the world on flood forecasting, flood alleviation scheme designs, flood risk mapping, flood risk assessments and catchment management planning projects. It delivers a set of flexible and cost effective tools to support flood risk management.
This latest edition to the ISIS suite of products is a fully hydrodynamic computational engine, designed to work as either a standalone or in conjunction with ISIS Professional (1D).
The software has been developed to complement the capabilities of software developer WBM’s 2D modelling software, TUFLOW, for which Halcrow is the UK agent. At the core of ISIS 2D, there are two numerical integrated solvers, ADI (Alternating Direction Implicit) and TVD (Total Variation Diminishing). These have been specifically developed to tackle different types of hydraulic conditions within rivers, estuaries and floodplains and so on.
You can purchase both ISIS 2D and TUFLOW from Halcrow, with a licensing and pricing structure that allows you to purchase only what you need, and the opportunity to network licences.
ISIS 2D is currently available at an introductory price of £2,950 (excluding VAT), with the network licence manager and TVD solver available at an additional cost of £950.
Alternatively, ISIS Free can be downloaded from www.halcrow.com/isis. ISIS Free has all of the same features as ISIS Professional and ISIS 2D, but is limited to 250 1D nodes, 2,500 2D cells and a 10MB restriction on ISIS Mapper input files.
