Flood modelling at Toddbrook Reservoir

In this webinar, Chris Allman, Senior Hydraulic Modeller and Hydrologist at Mott MacDonald, illistrates how an initial hydraulic model was developed following the Toddbrook Reservoir incident and how the uncertainties in the modelling were communicated to better manage the immediate risks to the community downstream. The webinar also shows how the model was used to highlight the role of the operational bywash during the incident.
