Abstract:
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.

Users should be aware that landform component delineation is fuzzy in that in most cases clear boundaries between landforms do not exist. In most instances only the mid and upper slopes and crests of sandy rises such as dunes and hummocks have been mapped. Users should refer to the final project report and "A study of the land of north-western Victoria" Rowan and Downes (1963) report. The report provides the methodology used to derive the landform dataset and identifies associated limitations, the Rowan and Downes (1963) report details the morphology and variation in landforms across the land systems of the Mallee.

Dataset Source: In 1963 Rowan and Downes published "Landsystems of north west Victoria" which broadly mapped and described land, land use, climate and vegetation patterns in the mallee region of Victoria. From 2009 to 2011 landform components described within each land system were disaggregated using a 10 meter resolution digital elevation model. 19 landforms classes were mapped in total across dryland agricultural areas. These mapped landforms provided the basis for this wind erosion susceptibility mapping.
