Port Phillip Bay Coastal Hazard Assessment - Inundation Extent - 0.2m Sea Level Rise With Rainfall (1% AEP)

The Port Phillip Bay Coastal Hazard Assessment (the product) is a digital dataset consisting of multiple spatial layer outputs from modelled erosion, inundation and groundwater hazard scenarios.\n\nThe product is recommended for use at the regional scale around Port Phillip Bay. Application of the data should be guided by the accompanying Port Phillip Bay hazard assessment technical reports (CSIRO 2022, Water Technology 2023, Kennedy 2022) and expert advice. The product is not suitable for individual property scale assessments.\n\nThe datasets available are as follows. Further detail on technical assumptions for these scenarios are provided in the accompanying technical reports. Additional data sets referenced in the reports are also available on request.\n\nStorm tide inundation\n\nStorm tide inundation extents for the 1% Annual Exceedance Probability (AEP) for a range of Sea Level Rise (SLR) scenarios (0m, 0.2m, 0.5m, 0.8m, 1.1m):\n- PPBCHA_INUNDATION_EXTENT_1AEP_00SLR\n- PPBCHA_INUNDATION_EXTENT_1AEP_02SLR\n- PPBCHA_INUNDATION_EXTENT_1AEP_05SLR\n- PPBCHA_INUNDATION_EXTENT_1AEP_08SLR\n- PPBCHA_INUNDATION_EXTENT_1AEP_11SLR\n- PPBCHA_INUNDATION_EXTENT_1AEP_14SLR\n- PPBCHA_INUNDATION_EXTENT_1AEP_00SLR_WITHRAINFALL\n- PPBCHA_INUNDATION_EXTENT_1AEP_00SLR_WITHRAINFALL\n- PPBCHA_INUNDATION_EXTENT_1AEP_05SLR_WITHRAINFALL\n- PPBCHA_INUNDATION_EXTENT_1AEP_08SLR_WITHRAINFALL\n- PPBCHA_INUNDATION_EXTENT_1AEP_11SLR_WITHRAINFALL\n- PPBCHA_INUNDATION_EXTENT_1AEP_14SLR_WITHRAINFALL\n\nStorm tide inundation extents for each SLR scenario are presented as a combined vector layer that incorporates the modelled 95th, 50th, and 5th percentiles.\n\nErosion\n\nErosion extents for the 1% AEP for a range of Sea Level Rise (SLR) scenarios (0m, 0.2m, 0.5m, 0.8m, 1.1m).\n- PPBCHA_EROSION_EXTENT_1AEP_2010_00SLR\n- PPBCHA_EROSION_EXTENT_1AEP_2040_02SLR\n- PPBCHA_EROSION_EXTENT_1AEP_2070_05SLR\n- PPBCHA_EROSION_EXTENT_1AEP_2100_08SLR\n- PPBCHA_EROSION_EXTENT_1AEP_2100_11SLR\n- PPBCHA_EROSION_EXTENT_1AEP_2100_14SLR\n\nErosion hazard extents are the modelled 95th percentile.

菲利普港湾海岸灾害评估数据集（以下简称本数据集）为数字化数据集，包含基于侵蚀、淹没与地下水灾害情景模拟生成的多套空间图层成果。

本数据集适用于菲利普港湾周边的区域尺度应用，数据使用需遵循配套的《菲利普港湾灾害评估技术报告》（CSIRO 2022、Water Technology 2023、Kennedy 2022）及专家指导意见。本数据集不适用于单个地块尺度的灾害评估工作。

本次公开的数据集如下所列。相关情景的技术假设细节已在配套技术报告中详述，报告中提及的额外数据集亦可按需申请获取。
