17.5 Overbank flood spilling

Supporting Information

The volume of overbank flow from rivers to the landscape during the 2010–11 year cannot be quantified accurately due to a lack of available data. However, it is likely that very little flooding occurred in the region during the 2010–11 year, so this volume is expected to be relatively small and its omission does not have a material impact on the water balance of the surface water store.
