Abstract

Study Objectives

The key objective of this Flood Study is to develop computational models that can be used as the basis for a Floodplain Risk Management Study and Plan for the study area. The study is also to assist SCC to undertake flood-related planning decisions for existing and future developments. The study covers the Lake Wollumboola catchment and the Culburra Beach village catchment. The components of the study were to:

• collate available historical flood-related data;
• analyse of historical rainfall and lake level data;
• undertake a community consultation program;
• develop numerical models of flooding in the catchment and calibrate them to historical data;
• determine the flood behaviour including design flood levels, velocities and flood extents within the catchment;
• to determine provisional residential flood planning levels and flood planning area;
• to assess the sensitivity of flood behaviour to potential climate change effects such as Lake Wollumboola Flood Study WMAwater 150917_LakeWollumboola_FloodStudy_Final:24 September 2015 5 increases in rainfall intensities and sea level rise; and
• to assess the floodplain categories in accordance with Council policy and undertake provisional hazard mapping.
