River Flood Hazard Zones (100 year CC Extent): The area potentially susceptible to river
flooding in a 1% AEP / 100Yr ARI + CC (climate change).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.
