Hillslope water erosion hazard was digitally mapped as part of the DPIPWE Water for Profit Program to enhance identification of Enterprise Suitability by effectively incorporating a sustainability measure of vulnerable soils. The mapping shows areas where a water erosion hazard might exist if sufficient groundcover is not maintained, which could lead to soil resource degradation through soil, organic matter and nutrient loss, resulting in sedimentation and contamination of drainage lines and waterways after significant rainfall and runoff events. Assigned classes are; Very Low, Low, Moderate, High, Very High and Extreme as classified ratings of a soil erosion. The index was generated as an erodibility factor (K) as part of the Revised Universal Soil Loss Equation (RUSLE), combining Digital Soil Mapping (DSM) inputs of the soil properties Coarse Fragments, Sand %, Silt %, Clay %, Organic Carbon %, Soil Permeability, and Soil Structure, with Slope and Slope-Length (from the SRTM Digital Elevation Model). The mapping covers the entire state of Tasmania at 30m resolution.

Soil waterlogging hazard was digitally mapped as part of the DPIPWE Water for Profit Program to enhance identification of Enterprise Suitability by effectively incorporating a sustainability measure of vulnerable soils. The mapping shows areas where a waterlogging hazard might exist if sufficient management is not applied, which could lead to soil resource degradation, trafficability issues and crop losses. Assigned classes are; Nil, Very Low, Low, Moderate, High and Very High as classified ratings of a waterlogging hazard index. The index was generated by combining Digital Soil Mapping (DSM) inputs of the soil properties of soil drainage index and permeability index, and mapped areas of flood risk, where very poor drainage and low permeability imply a high waterlogging hazard, and rapid drainage and high permeability imply a low waterlogging hazard. The mapping covers the entire state of Tasmania at 30m resolution.

Soil sodicity hazard was digitally mapped as part of the DPIPWE Water for Profit Program to enhance identification of Enterprise Suitability by effectively incorporating a sustainability measure of vulnerable soils. The mapping shows areas where a sodicity hazard might exist if sufficient management is not applied, which could lead to soil resource degradation. Assigned classes are; Nil, Low, Moderate and High as classified ratings of a sodicity hazard index. The index was generated by combining Digital Soil Mapping (DSM) inputs of the soil properties of Exchangeable Sodium Percentage (ESP) for standard depths, with ratings developed by the DPIPWE Land Degradation and Salinity Risk assessments. The mapping covers the entire state of Tasmania at 30m resolution.

Wind Erosion risk mapping derived from land quality attribution associated with soil-landscape mapping at the subsystem/phase level. See Resource Management Technical Report 298, Section 2.22, Department of Agriculture, 2005.
