Wind erosion susceptibility mapping for north west Victoria
A polygonal map of wind erosion susceptibility in the Victorian Mallee. The dataset was created by assigning relative susceptibility classes to landform component data mapped during the disaggregation of land systems project (refer to separate metadata entry). The classifications represent the inherent susceptibility of the component to wind erosion based on its exposure to erosive winds and its 'likely' soil texture grade. In some instances a landform component has been split into facets in order to assign varying classes of susceptibility across the component. The project was sponsored by the Mallee Catchment Management Authority with funding from the Federal government's Caring for our Country initiative. The final project report, "Mallee wind erosion susceptibility mapping" together with the "Disaggregation of landform components within land systems of the Mallee", and the Rowan and Downes (1963) report , "A study of the land of north-western Victoria", should be referred to when analysing or utilising this dataset. Regional Map Units (RMUs) in the Mallee developed during the land system disaggregation project and refined in this project have been ranked for their overall wind erosion susceptibility. These units and the finer-scale grid data can be used to make spatially strategic decisions for investment in research, monitoring, protection and management relating to wind erosion in the region.

Dept of Environment, Water and Natural Resources - Soil Wind Erosion Potential
공공데이터포털
Wind erosion potential, based on Soil Landscape Map Units of Southern South Australia, describes the susceptibility of land to erosion by wind, which is particularly an issue on sand and sandy loam soils. Mapping shows the degree and variability of wind erosion potential, while detailed proportion data are supplied for calculating respective areas of each wind erosion potential class (spatial data statistics).

Landform component mapping of north west Victoria
공공데이터포털
A polygonal dataset of mapped landforms in the Victorian Mallee. The dataset was created from the disaggregation of land systems originally defined by Rowan and Downes (1963). The disaggregation primarily involved an analysis of a 10 metre grid Digital Elevation Model (DEM) provided by the Department of Sustainability and Environment. The analysis included the use of the UPNESS index from the Fuzzy Landscape Analysis GIS (FLAG) model, Multi-resolution Valley Bottom Flatness (MrVBF) index, DEM derivative surfaces (such as slope, curvature, aspect and relative elevation) in combination with expert opinion, field observations and other supplementary datasets (such as aerial imagery, radiometrics, vegetation and GMU). The dataset was created in a staged approach through 4 project phases. The project was sponsored by the Mallee Catchment Management Authority with funding from the Federal government's Caring for our Country initiative. The final project report, "Disaggregation of landform components within land systems of the Mallee", and the Rowan and Downes (1963) report , "A study of the land of north-western Victoria", should be referred to when analysing or utilising this dataset. The landform component mapping was supplemented and refined during a "Wind erosion susceptibility mapping" project conducted in 2011. Details of changes are included in the associated project report (refer to that metadata record).
A ranking of wind erosion risk for agricultural lands (2017)
공공데이터포털
This dataset is a ranking of estimated wind erosion risk for agricultural lands. Agricultural lands are defined here as those areas under cropping and grazing. The dataset was created in a multi-criteria analysis by combining (i) a modelled map of wind erosion severity for the period 2000 to 2010, (ii) an index map of the total soil nutrient loss, and (iii) maps of ‘room for improvement’ in ground cover management on agricultural lands within natural resource management (NRM) regions. It was developed to be used with a priority ranking for each NRM region to locate where in a NRM region the wind erosion investment area is and its priority. Definition of classes 1. Low risk of wind erosion for agricultural land 2. Moderate risk of wind erosion for agricultural land 3. High risk of wind erosion for agricultural land Detail on how the dataset was created is in Leys et al. (2017).
