The potential soil erosion map per parcel (2013) shows the total potential erosion of a given agricultural parcel on the basis of a classification. Total potential erosion does not take into account current land use (grassland or cropland) and is the sum of processing erosion and water erosion. Erosion by water is a process in which soil particles are loosened and transported by the impact of raindrops and run-off water, either layered over a large surface area or concentrated in gullies and ravines. This leads, among other things, to a decrease in soil quality and productivity, but also to significant damage due to mud nuisance in downstream (residential) areas. It can be argued that erosion is one of the most important forms of soil degradation in Flanders. The potential soil erosion map per parcel is based on the parcel map 2012. Because the parcel map 2012 is not area-wide for the whole of Flanders, part of the agricultural use data was derived from a classified satellite image of OCGIS Flanders. However, this image only contains land use information and no plot information, so the calculations for this area will obviously be of a much lower quality. The potential soil erosion map per plot was drawn up by means of computer modelling with a spatial resolution of 5 m (Research Group Physical and Regional Geography, Department of Earth and Environmental Sciences, K.U.Leuven). The calculation of water erosion is based on the revised universal soil loss equation or R.U.S.L.E. (Revised Soil Loss Equation, Renard et al, 1991). It is an empirical model that calculates the average annual soil erosion rate per unit area due to intergeal and geulerosion as a product of 6 factors: The machining erosion was calculated using Software based on the water edema model.
