Port Phillip Bay Coastal Hazard Assessment - Inundation Extent - 1.1m Sea Level Rise With Rainfall (1% AEP)

dataset: PPBCHA_INUNDATION_EXTENT_1AEP_11SLR_WITHRAINFALL

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. The 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. The 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. Storm tide inundation Storm 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): - PPBCHA_INUNDATION_EXTENT_1AEP_00SLR - PPBCHA_INUNDATION_EXTENT_1AEP_05SLR - PPBCHA_INUNDATION_EXTENT_1AEP_08SLR - PPBCHA_INUNDATION_EXTENT_1AEP_11SLR - PPBCHA_INUNDATION_EXTENT_1AEP_14SLR - PPBCHA_INUNDATION_EXTENT_1AEP_00SLR_WITHRAINFALL - PPBCHA_INUNDATION_EXTENT_1AEP_05SLR_WITHRAINFALL - PPBCHA_INUNDATION_EXTENT_1AEP_08SLR_WITHRAINFALL - PPBCHA_INUNDATION_EXTENT_1AEP_11SLR_WITHRAINFALL - PPBCHA_INUNDATION_EXTENT_1AEP_14SLR_WITHRAINFALL Storm tide inundation extents for each SLR scenario are presented as a combined vector layer that incorporates the modelled 95th, 50th, and 5th percentiles. Erosion Erosion extents for the 1%AEP for a range of Sea Level Rise (SLR) scenarios (0m, 0.2m, 0.5m, 0.8m, 1.1m). - PPBCHA_EROSION_EXTENT_1AEP_2010_00SLR - PPBCHA_EROSION_EXTENT_1AEP_2040_02SLR - PPBCHA_EROSION_EXTENT_1AEP_2070_05SLR - PPBCHA_EROSION_EXTENT_1AEP_2100_08SLR - PPBCHA_EROSION_EXTENT_1AEP_2100_11SLR - PPBCHA_EROSION_EXTENT_1AEP_2100_14SLR Erosion hazard extents are the modelled 95th percentile. Sea level of 0m as of 2010. Groundwater Groundwater extents indicating where the hazard is shallow (within 0 to 2m below land surface) for a range of Sea Level Rise (SLR) scenarios (0m, 0.2m, 0.5m, 0.8m): - PPBCHA_GROUNDWATER_EXTENT_SHALLOW_00SLR - 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 Shallow groundwater extent layer is derived from the groundwater depth raster.
