The ISC2010_VEGETATION_OVERHANG_S table is the Statistical Summary table for the Vegetation Overhang Metric at the 100m Section level. The ISC2010_VEGETATION_OVERHANG_S table is designed to JOIN to the ISC2010_RIVER_CENTRELINES_S feature class. River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC). The Department of Environment and Primary Industries (DEPI) developed a methodology to assess the Physical Form and Riparian Vegetation components of the ISC using remote sensing data, specifically LIDAR and aerial photography. A State Wide mapping project was undertaken in 2010-13 to accurately map the Physical Form and Riparian Vegetation metrics of the ISC . Other ISC metrics were not assessed in the project and were derived from other sources. The Physical Form and Riparian Vegetation Metric products are a combination of mapped Vector and Raster data as well as Tabular Summary Statistics about the mapped features. In the context of the project, the term Metrics is used to refer to both the mapped features and the summary statistics. Remote sensing data used includes 15cm true colour and infra-red aerial photography and four return multi-pulse LiDAR data. This source data was used to derive a variety of Raster data sets including Digital Terrain Models, Slope, Vegetation Height and Vegetation Cover. The Digital Terrain and Slope rasters were used to map Physical Form metrics including Stream Bed, Top of Bank and River Centre Lines while the Vegetation Height and Cover rasters were used to map the Riparian Vegetation metrics. The Project Report "Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping" describes the remote sensing and mapping approach used to create this data set.

Estimated long-term mean annual temperature interpolated to a 500m grid cell using the DEM250 layer and the ESOCLIM software.

Projection data is described in the gridcode column of the attribute table. This number is 1000 times the actual value (retained in this form to capture significant figures through map processing). For example, "Gridcode -23599" equates to -24% (rainfall) and "Gridcode 1986" equates to 2.0 degrees Celsius (temperature). The results are from 23 climate models that were available for the IPCC Fourth Assessment Report (2007). It is assumed that that the model results give a representation of the real world response to a specific emissions scenario. The IPCC (2007) estimates of global warming are relative to the period 1980-1999. For convenience, the baseline is often called 1990. Projections are given for 2030 and 2070 but, of course, individual years can vary markedly within any climate period, so the values can be taken as representative of the decade around the single year stated, i.e. projections for 2030 are representative of 2026-2035. Natural variability (independent of greenhouse gas forcing) can cause decadal means to vary and estimates of this effect are included in the estimates of uncertainties. The projections comprise a central estimate and a range of uncertainty. The central estimate is the median – or 50th percentile - of the model results, while the uncertainty range is based on two extreme values – the 10th and 90th percentiles. 10% of values fall below the 10th percentile and 10% of values lie above the 90th percentile. Greater emphasis is given to projections from models that best simulate the present climate. The weightings are based on statistical measures of how well each model can simulate the 1975-2004 average patterns of rainfall, temperature, and sea level pressure over Australia. Subregions of Victoria are indicated. Victoria has an integrated catchment management system established under the Catchment and Land Protection Act 1994 (the CaLP Act). Under the CaLP Act, Victoria is divided into ten catchment regions, with a Catchment Management Authority (CMA) established for each region.

Victorian State-wide dataset containing features of interest including boating clubs, camping grounds, caravan parks, historic sites, lifesaving clubs and lookouts as identified by the Victorian Regional Coastal Boards and reviewed as part of the Future Coasts SECAP project.

The Victorian Coastal Inundation Dataset (the product) is a digital dataset consisting of eight spatial layers modelling the extent of land subject to coastal inundation due to projected sea level rise from 2009 to 2100. 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. The datasets available are: Sea Level Rise: - SLR00CM_2009 - Current (2009) sea level - SLR20CM_2040 - Projected 20cm sea level rise by 2040 - SLR47CM_2070 - Projected 47cm sea level rise by 2070 - SLR82CM_2100 - Projected 82cm sea level rise by 2100 Storm tide (1-in-100 year) with added wind forcing plus sea level rise - SLR00CM_ST_2009 - Current (2009) inundation to 1-in-100 year storm tide level - SLR20CM_ST_2040 - Inundation to 1-in-100 year storm tide level with storm surge increased by 6% plus 20 cm sea level rise - SLR47CM_ST_2070 - Inundation to 1-in-100 year storm tide level with storm surge increased by 13% plus 47 cm sea level rise - SLR82CM_ST_2100 - Inundation to 1-in-100 year storm tide level with storm surge increased by 19% plus 82 cm sea level rise Interactive Map:- Hydra site decommissioned on 25/10/2022 as requested by the site owner. http://mapshare.maps.vic.gov.au/gvh270hydra/ > Future Coasts (Modelled) This data has been computed to support the Victorian Governments Future Coasts Project.
