Description:

River Flood Hazard Zones (10 year Extent): The area potentially susceptible to river flooding in a 10% AEP / 10Yr ARI.

Regionwide River flood hazard zones were developed by 2 different external expert consultants between 2016 (Priority Rivers) and 2021 (Regionwide Models). The layers are derived by advanced models using empirical calculations.  

Two different models were used to construct the river flood layers: TUFLOW (Water Technology, 2021), InfoWorks (URS, 2016). The reports detailing the methodologies, and risk assessment on the Priority Rivers, can be accessed from the NRC website.
