Purpose

This product is recommended for use at a scale of approximately 1:75,000 or less detail to reflect the limitations in the modelling and the recommended catchment to regional scale of inundation assessments with this product. The product is NOT suitable for assessments of potential risks at property level. Areas of application include: Strategic planning, Adaptation planning, Risk assessment, Catchment hydrological modelling.

Statement

Dataset Source: The Victorian Coastal Inundation Dataset has been computed using the Coastal Inundation model developed and processed by the University of Tasmania, using input data from a number of source datasets of varying spatial accuracy and temporal scale. The inputs used to compute coastal inundation are: - Vicmap Elevation - Coastal 1m (LiDAR) DEM & 0.5m Contours - Predictions of sea level rise from the Intergovernmental Panel on Climate Change (IPCC) - The National Tidal Centre modeled high water from the Bureau of Meteorology (BOM) - Modeled storm tide levels and wind forcing modeling from Australian Commonweatlh Scientific and Research Organisation (CSIRO) Dataset Originality: Primary & Derived 

Description

Four sea level scenarios were applied to the Victorian 1m Coastal DEM. The components combined to form the two scenarios are: - Predictions of sea level rise - High Water modeled levels - Storm Tide modeled levels - Wind forcing modeling The Coastal Inundation model predicts inundation for two scenarios at four time scales: Incremental sea level based on the National Tidal Centre tidal range grid - Present day (2009) scenario - 20 cm sea level rise consistent with IPCC A1FI 2040 scenario - 47 cm sea level rise consistent with IPCC A1FI 2070 scenario - 82 cm sea level rise consistent with IPCC A1FI 2100 scenario Storm tide (1-in-100 year) with added wind forcing - Present day (2009) scenario (inundation to 1-in-100 year storm tide level) - IPCC A1FI 2040 scenario (inundation to 1-in-100 year storm tide level with storm surge increased by 6% plus 20 cm sea level rise) - IPCC A1FI 2070 scenario (inundation to 1-in-100 year storm tide level with storm surge increased by 13% plus 47 cm sea level rise) - IPCC A1FI 2100 scenario (inundation to 1-in-100 year storm tide level with storm surge increased by 19% plus 82 cm sea level rise) The Coastal Inundation processing model uses a "bathtub" method, whereby sea level heights are computed against DEM heights with no consideration for water flow or drainage/stream connectivity. The Coastal Inundation dataset has been subject to cartographic generalisation to ensure cartographic clarity and usability for a scale use of 1:75,000 or less detail.
