Lake Wollumboola Flood Study

__Study Objectives__\r\n\r\nThe key objective of this Flood Study is to develop computational models that can be used as\r\nthe basis for a Floodplain Risk Management Study and Plan for the study area. The study is\r\nalso to assist SCC to undertake flood-related planning decisions for existing and future\r\ndevelopments.\r\nThe study covers the Lake Wollumboola catchment and the Culburra Beach village catchment.\r\nThe components of the study were to:\r\n\r\n* collate available historical flood-related data;\r\n* analyse of historical rainfall and lake level data;\r\n* undertake a community consultation program;\r\n* develop numerical models of flooding in the catchment and calibrate them to historical\r\ndata;\r\n* determine the flood behaviour including design flood levels, velocities and flood extents\r\nwithin the catchment;\r\n* to determine provisional residential flood planning levels and flood planning area;\r\n* to assess the sensitivity of flood behaviour to potential climate change effects such as\r\nLake Wollumboola Flood Study\r\nWMAwater\r\n150917_LakeWollumboola_FloodStudy_Final:24 September 2015\r\n5\r\nincreases in rainfall intensities and sea level rise; and\r\n* to assess the floodplain categories in accordance with Council policy and undertake\r\nprovisional hazard mapping.
