Wind erosion in NRM regions

Use the map to identify the months which were most, or least, affected by wind erosion in recent years (2000-2012). Data is available for most NRM regions of Australia. Use the knowledge to strengthen your wind erosion and ground cover management planning.

Information

Information About

The wind erosion data is a record of which months suffered wind erosion most, and which didn't. The graph shows the percentage of the NRM region affected by varying degrees of erosion (from Very Low to Very High wind erosion). When viewed together as a time period (2000-2012), you can see which months/years were 'good' years, and which years suffered more erosion than usual.

Modelled Wind Erosion uses a numerical model called CEMSYS (Computational Environmental Management System) to create modelled monthly and annual wind erosion maps of Australia at 50 km resolution. For each pixel (50 km x 50km), a wind erosion severity level was calculated and classified as either very low, low, moderate, high or very high erosion. Then for each Natural Resource Management (NRM) region the percentage of land area affected by each wind erosion severity class was calculated. Read more about the project...

Geographic markers Geographic markers

The geographic markers in the map are 'NRM regions'. These are natural resource management regions as defined by the Australian Government, and further refined as per the report by Leys et al. 2009 "Improving the capacity to monitor wind erosion in Australia"

What is available

The following maps display Wind Erosion Rates for Australia which have been modeled for every month from Feb 2000 to Jun 2012. The wind erosion rate is the rate that soil is blown away by the wind. It is expressed here as mg/m/s

Each coloured pixel on the map is an area of land 50km x 50 km. You'll notice that wind erosion rates vary across Australia, and also from month to month.
