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本洪水研究以水位达到澳大利亚高程基准（Australian Height Datum, AHD）下RL2.476米的泄放阈值时，将科克龙泻湖（Cockrone Lagoon）与海洋连通的场景作为核心研究内容。本政策旨在最大程度降低泻湖周边毗邻地产的洪涝风险。 本洪水研究所采用的调研流程如下： * 现有数据的收集 * 现有数据的评估 * 泻湖运行特征概览 * 海岸动力过程评估 * 开展流域水文建模以确定洪水入流量 * 开展泻湖水动力建模以基于洪水入流量评估洪涝水位
