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. Sea level of 0m as of 2010.\n\nGroundwater\n\nGroundwater 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):\n- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_00SLR\n- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_02SLR\n- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_05SLR\n- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_08SLR\n- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_11SLR\n- PPBCHA_GROUNDWATER_EXTENT_SHALLOW_14SLR\n\nShallow groundwater extent layer is derived from the groundwater depth raster.\n\nReport Citations:\n\nCSIRO - McInnes, K.L., O\u2019Grady, J.O., Prakash, M., Dahlhaus, P., Rosengren, N.J., Hoeke, R.K., Lauchlan Arrowsmith, C., Hernaman, V., Cohen, R., Seers, B., Chen, Y., Walters, D., Couto, P., Trenham, C., Forbes-Smith, N.
