Contains all TUFLOW model input and model output files for existing as well as flood mitigation model runs

TUFLOW hydraylic models for caclulating flood damages

Contains Result files for design events, sensitivity events and blockage assessment

An update of the modelling outputs for the Williams River Flood Study tying the model into the Williamtown Flood Study model.

Appendix B - Figures

The following report forms the Floodplain Risk Management Study and Plan for the Wyong River Catchment. The report is presented in two volumes: Volume 1 (this document) contains the report text and appendices; and, Volume 2 (separate A3 document) contains all complementary maps/figures. Volume 1 has been divided into the following sections: Section 2 - Background Information: Provides general information regarding the catchment, including the history of flooding as well as existing planning and emergency response protocols Section 3 – The Existing Flood Risk: Describes the current impact of flooding on the community for a range of different floods. This includes an assessment of the impact of flooding on key facilities, the potential cost of flooding as well as the potential for floodwater to damage buildings and/or pose a danger to personal safety. Section 4 – Current Planning Measures: summarises the main legislation, policy and guidelines that affect the development of land. Section 5 – Current Emergency Management Protocols: provides an overview of emergency management measures that are currently implemented across the catchment to assist in managing the flood risk. Opportunities to improve these existing protocols are also discussed. Sections 6 to 9: discusses the merits of a range of flood, property and response modification measures that could be potentially implemented to manage the existing, future and continuing flood risk across the catchment Section 10 – Draft Floodplain Risk Management Plan: provides a preferred list of options that are considered appropriate for adoption by Council to manage the flood risk.
