Description
Dr Chris Whitlow of Edenvale Young has been at the forefront of flood forecasting in the UK since in 1997, when he successfully demonstrated the application of real time hydrodynamic flow forecasting using ISIS for the Orange River in South Africa. In 1999, EdenVale Modelling Services (before we became Edenvale Young Associates) developed a real-time flood forecasting system (GeoGUI).GeoGUI was generated for the River Eden for North West Region of the Environment Agency
GeoGUI is still used as the primary tool for flood forecasting in Thames Region for the fluvial Thames to Farmoor (upstream of Oxford) as well as the Rivers Lee, Colne, Cherwell and Loddon. In 2001, the Environment Agency made a decision to develop a National Flood Forecasting System (NFFS) and the specification and ITT for this (open) system was written primarily by Dr. Whitlow who was employed as the key technical consultant until the project was successfully concluded for all 8 regions in 2007. As a result of this involvement, we now have extensive knowledge of the NFFS system operation, having configured several catchments such as the Tidal Trent, Middle Severn, Monks Brook and River Itchen. We have also provided third party reviews for many forecasting models supplied by other UK consultants.
Edenvale Young Associates is currently engaged by Midlands Region of the Environment Agency in developing and configuring Forecasting Models for the Upper Severn and Soar catchments as well as reviewing forecasting performance during the summer 2007 floods. For Thames region, we have already written an equivalent document and are currently working on forecasting model development for several catchments. Edenvale Young Associates has also worked closely with Halcrow in the development of the Bristol Avon Forecasting models and as sub-consultants to Halcrow’s Glasgow office on the project to develop pilot forecasting models within the same system (Delft FEWS) in Scotland for SEPA.
