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, 0.2m, 0.5m, 0.8m, 1.1m): - 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 - PPBCHA_INUNDATION_EXTENT_1AEP_00SLR_WITHRAINFALL - 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.

Winterfill sustainable diversion limit volumes (SDLs) have been developed across Victoria and represent the upper limit on winterfill diversions, beyond which there is an unacceptable risk that additional extractions may degrade the environment. The SDL_BASIN dataset is a spatial representation of river basins, which represent an aggregate of the intermediate SDL catchments. These basins DO NOT reflect the Victorian surface water river basins as defined by the Australian Water Resources Council. Winterfill SDL data is held in the SDL_DATA layer.

Point data describing the location and key characteristics of all PGPs that are currently under active management by VicForests. The data consists of one point for each PGP that is classified as 'current' in VicForests' network of PGPs. PGPs that have been retired or abandoned are not included in the dataset. PGPs are permanently demarcated areas of forest that are periodically measured over long periods of time (20-50 years) and they require protection from unplanned disturbance events such fuel reduction burns.

This layer contains the line and polygon features depicting the former 16 DCE Regional boundaries at 1:100,000.

This layer contains the relative forest growth stage classes. The classification is based on Eucalypt growth stages identified by Max Jacobs (Growth habits of the eucalypts, 1955) and described in terms of the relative contribution of irregular to regular to regrowth forms to the total crown cover. The data has been collected to SFRI standards for the old growth forest mapping program.
