ISIS-TUFLOW

In early 2004, TUFLOW was benchmarked against other packages in preparation for selecting a modelling system for the Tidal Thames Embayments Inundation Study. The investigations were commissioned by the UK Environment Agency who requires a tool to improve its ability to plan for and manage a storm tide flood event that breaches or overtops the defences along the River Thames, London. This tool would generate predictions to give emergency response teams and the public reliable information regarding the extent, timing and nature of the propagation of floodwaters. Halcrow, in conjunction with HR Wallingford, were commissioned to carry out the study and the benchmarking.

After the benchmarking, TUFLOW was selected as the preferred 2D system. In July 2004, the ISIS 1D engine and TUFLOW engine were then dynamically linked and merged as one computational engine. The ISIS-TUFLOW engine is now being used to cover all 23 embayments through the City of London. The EA's considerable investment in the Thames ISIS 1D model has been preserved, and the 2D capabilities of TUFLOW allows the complex flow patterns in the embayments, associated with breaching or overtopping of the defence walls, to be accurately modelled.

ISIS-TUFLOW is now available as a commercial product. For more information on the ISIS-TUFLOW Link click here.
