Port Phillip Bay Coastal Hazard Assessment - Inundation Extent - 0.8m Sea Level Rise (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, 0.5m, 0.8m, 1.1m):\n- PPBCHA_INUNDATION_EXTENT_1AEP_00SLR\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_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得到的多空间图层输出成果。

本数据集推荐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）及专家建议。本数据集不适用于单宗地产尺度的灾害评估。

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。报告中引用的其他数据集亦可按需获取。

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

海岸侵蚀灾害范围为模拟得到的95th百分位数结果，其中0m海平面上升情景对应2010年基准海平面。

## 地下水灾害
针对不同海平面上升（SLR）情景（0m、0.2m、0.5m、0.8m、1.1m、1.4m）下的浅层地下水灾害范围（灾害点位于地表以下0至2米范围内）：
