The Byron Shire Council commissioned JB Pacific to undertake a comprehensive assessment and review flood trigger levels and flood warning classifications for the Byron Shire flood warning gauge network. The pilot study involved a comprehensive assessment of five gauges, which utilised diverse data sources such as historic data, hydraulic modelling and LiDAR imagery.
The findings resulted in three distinct trigger levels (Low, Medium, High) and flood classifications (Minor, Moderate, Major) suggested for each gauge. The study involved creating a methodology to produce new trigger levels and flood warning classifications, which incorporated analyses of historic flood levels and a GIS based assessment of inundation to identify critical points for assets and infrastructure. The refined classifications offered a nuanced understanding of potential flooding scenarios, which provided decision-makers and communities with essential tools for proactive flood preparedness and response
