Potential soil erosion map per parcel (2017)
Description
The potential soil erosion map per parcel (2017) shows the total potential erosion of a given agricultural parcel using a classification. Total potential erosion does not take into account current land use (grassland or cropland). The field ‘Single application for erosion susceptibility’ contains the information corresponding to the erosion susceptibility on the 2017 single application. The approved objections were processed both in the field 'Single application for corrosion sensitivity' and in the field 'Total erosion'. The approved applications for the reduction of the erosion sensitivity class based on high carbon content were processed in the field 'Erosion sensitivity single application' indicating '/ C' behind the erosion sensitivity, but the field 'Total erosion' retained its original value for these parcels. On 25 April 2017, the potential soil erosion map per parcel (2017) was updated with additional approved objections and applications from other erosion-related soils and reduction of the erosion susceptibility class based on high carbon content. 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. Soil 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 2016. The potential soil erosion map per plot was drawn up by means of computer modelling with a spatial resolution of 5x5 m (Research Group Physical and Regional Geography, Department of Earth and Environmental Sciences, K.U.Leuven). The calculation of erosion is based on the revised universal soil loss equation or R.U.S.L.E. (Revised Universal 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.
