Cockrone Lagoon Flood Study

Flood study centres around the opening of Cockrone Lagoon to the ocean when the water level exceeds the let-out-level of RL2.476m AHD. The policy is aimed at minimising the flooding of properties adjacent to the lagoon.\r\n\r\nThe investigation process used in this flood study was:\r\n\r\n* collection of available data\r\n* assessment of available data\r\n* overview of lagoon behaviour\r\n* assessment of coastal processes\r\n* hydrologic modelling of the catchment to determine flood inflows, and\r\n* hydraulic modelling of the lagoon to assess flood levels from flood inflows
