In June 2007 the River Don experienced a 1 in 200 year flood event that caused widespread flooding along the Don Valley. During this event the River Don District Masterplan area and the adjacent Meadowhall Shopping Centre were partially flooded, causing extensive damage and loss of trade.
PBA undertook detailed modelling of the area to advise on the upgrading of existing flood defences to reduce the future impact of any flood events of this scale. We have been working on the hydraulic modelling of the River Don since 2005 to fully understand the complex flood mechanisms associated with flooding in this heavily urbanised area.
We built a new, more complex version of an existing Environment Agency model to ensure it was suitable for development control.
