The Gloucester and Avon Rivers Flood Study has been prepared for Gloucester Shire Council (Council) to define the existing flood behaviour in the catchment and establish the basis for subsequent floodplain management activities. This project has been implemented through the Gloucester Water Study Project. The primary objective of the Flood Study is to define the flood behaviour within the Gloucester and Avon Rivers catchment through the establishment of appropriate numerical models. The study has produced information on flood flows, velocities, levels and extents for a range of flood event magnitudes under existing catchment and floodplain conditions. Specifically, the study incorporates: Compilation and review of existing information pertinent to the study and acquisition of additional data including survey as required; Development and calibration of appropriate hydrologic and hydraulic models; Determination of design flood conditions for a range of design event including the 50% AEP, 20% AEP, 10% AEP, 5% AEP, 2% AEP, 1% AEP, 0.5% AEP, 0.2% AEP and PMF event; and Presentation of study methodology, results and findings in a comprehensive report incorporating appropriate flood mapping.
