New R&D report on benchmarking the latest 2D models reveals the power of XPSTORM

Posted: Wednesday 23rd October 2013

XPSTORM performed strongly in the latest round of 2D benchmarking tests conducted on behalf the Environment Agency. This TUFLOW powered, integrated 1D and 2D hydraulic/hydrology software is used extensively throughout the world. The Environment Agency’s latest tests have confirmed that it is a strong newcomer to hydraulic modelling in the UK.

Under the direction of Prof Garry Pender (Herriot Watt University) and Stefan Laeger (Environment Agency), an extensive Research Project has been undertaking on ‘Benchmarking the latest generation of 2D hydraulic modelling packages’ (SC120002). Conducted over the last year, these tests are one of the most comprehensive head to head analyses of 2D hydraulic modelling tools available for use in flood and coastal risk management the UK.

Mr Laeger explains, “2D hydraulic flood models are a vital tool in assessing flood risk and the effects of interventions. They support many vital applications including flood mapping, wider risk assessment and appraisal of options as well as supporting the design of structural measures such as flood defences.

This research produced up-to-date evidence of which hydraulic modelling packages are suitable for which types of flood risk management modelling applications so that Environment Agency operational teams and practitioners can apply available flood modelling tools with confidence.”

Micro Drainage’s David Fortune commented, “We’re so excited to finally have an accurate reflection of just what XPSTORM can do. We have developed this product over 20 years and it is used extensively elsewhere in the world, but it’s still very new to the UK. We are proud of XPSTORM’s consistent results and this demonstration of its performance against some of the more established brand names in the UK modelling space.”

The report tested a number of complex scenarios to determine the software ‘fit for purpose’ for a range of uses including: Flooding a disconnect water body, Filling of floodplain depressions, Momentum conservation over a small obstruction, Speed of flood propagation over an extended floodplain, Valley flooding, Dambreak, River and floodplain linking, Rainfall and point source surface flow in urban areas, Surface flow from a surcharging sewer in urban areas, and Run times.

On top of the benchmarking performance, XPSTORM brings seamless integration with WinDes (the UK standard sustainable drainage design package).
