|The Susceptibility to Wind Erosion map is intended to be used with existing Land Systems data to determine the likely impact of wind erosion for areas within the catchment region.|
Criterion is based on Lorimer (1985) and uses surface texture in semi-arid to sub-humid areas and exposure to particularly strong winds in humid areas. The criterion for susceptibility to wind erosion in semi-arid areas is surface soil texture. Scores are given to rate texture from nil to high.
|Most areas within North Central have nil, low or moderate susceptibility to water erosion. Those areas with low susceptibility are generally plains above flood level with grassy woodlands and broadacre cropping and cropping/pasture land use. These are quite extensive areas throughout the north of the catchment area and smaller patches of land in the southern half of the region.|
Those areas in the North Central region which are likely to have low to moderate susceptibility to water erosion are generally grassland plains above flood level whose chief land uses are broadacre cropping and dryland pasture.
|The Susceptibility to Water Erosion map is intended to be used with existing Land Systems data to determine the likely impact of wind erosion for areas within the catchment region.|
Measurement is based on McDonald at al (1990) and uses soil depth (the average depth to solid rock). Rating scores are based on observations in hilly sub-humid areas where water erosion is relatively severe. These scores are rated from nil to high.
