Current Flood Risk
The first stage in the coastal flood modelling involved the consideration of the local coastal processes and key mechanisms of flooding, as it is essential that the modelling accounts for these processes in as realistic manner as possible.
The figure below illustrates the main components that contribute to coastal flooding during a storm event. Historical events have shown that flood risk due to still water levels (SWL) alone is limited within Stonehaven and Cowie, with wave overtopping being the primary mechanism that results in coastal inundation.
The modelling was calibrated against anecdotal evidence from the December 2012 event. These modelled flood outlines are presented below along with those for the 2 and 200 year present day and climate change events. A link to the Interim Modelling Report is also provided; this provides full details of the modelling undertaken.
