Port Phillip Bay Coastal Hazard Assessment

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- PPBCH A_INUNDATION_EXTENT_1AEP_00SLR_WITHRAINFALL\n- PPBCHA_INUNDATION_EXTENT_1AEP_02SLR_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（本数据集产品）是一套数字化数据集，包含基于模拟得到的海岸侵蚀、风暴潮淹没与地下水灾害情景的多空间图层输出成果。

本数据集产品推荐用于菲利普港湾周边的区域尺度分析。数据的应用需遵循配套的《菲利普港湾灾害评估技术报告》（CSIRO 2022、Water Technology 2023、Kennedy 2022）及专家建议。本数据集不适用于单个物业尺度的灾害评估工作。

本次公开的数据集如下。关于各灾害情景的技术假设细节，请参阅配套技术报告。报告中提及的其他数据集亦可按需申请获取。

风暴潮淹没
针对不同海平面上升（Sea Level Rise, SLR）情景（0米、0.2米、0.5米、0.8米、1.1米、1.4米）下的1%年超越概率（Annual Exceedance Probability, AEP）风暴潮淹没范围：
- PPBCHA_INUNDATION_EXTENT_1AEP_00SLR
- PPBCHA_INUNDATION_EXTENT_1AEP_02SLR
- PPBCHA_INUNDATION_EXTENT_1AEP_05SLR
- PPBCHA_INUNDATION_EXTENT_1AEP_08SLR
- PPBCHA_INUNDATION_EXTENT_1AEP_11SLR
- PPBCHA_INUNDATION_EXTENT_1AEP_14SLR
- PPBCH A_INUNDATION_EXTENT_1AEP_00SLR_WITHRAINFALL

各海平面上升情景下的风暴潮淹没范围以合并矢量图层形式呈现，该图层包含模拟得到的95分位、50分位与5分位淹没结果。

海岸侵蚀
针对1%年超越概率的海岸侵蚀范围，覆盖不同海平面上升情景（0米、0.2米、0.5米、0.8米、1.1米、1.4米），具体如下：

- PPBCHA_EROSION_EXTENT_1AEP_2070_05SLR
- PPBCHA_EROSION_EXTENT_1AEP_2100_08SLR
- PPBCHA_EROSION_EXTENT_1AEP_2100_11SLR
- PPBCHA_EROSION_EXTENT_1AEP_2100_14SLR

海岸侵蚀灾害范围为模拟得到的95分位结果，其中海平面基准为2010年的0米。

地下水灾害
地下水灾害范围图层用于标识灾害潜势较浅（距地表0至2米以内）的区域，覆盖不同海平面上升（Sea Level Rise, SLR）情景（0米、0.2米、0.5米、0.8米、1.1米、1.4米）：

- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_02SLR
- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_05SLR
- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_08SLR
- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_11SLR
- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_14SLR

浅层地下水灾害范围图层由地下水深度栅格数据衍生得到。
