Baseland use sediment modelling (2022)
Description
Soil erosion leads to sediment transport through the landscape until sedimentation occurs on land or the sediment flow reaches watercourses, canals or sewers. This data layer represents the land use used as a basis for modelling erosion and sediment transport. The modelling was carried out with the CN-WS model version 4.2.3 in combination with pycnws version 0.6.3. The calculation was made on the scale of Flanders at a resolution of 20 m. This data layer is an indication of land use, divided into the classes of arable land, grassland, grass strips, forest, infrastructure, water surfaces and watercourses. Agricultural parcels are considered grassland if they have a permanent crop cover for at least 2 consecutive years. All other agricultural parcels are considered to be average arable land. The modelling is based on the 2022 agricultural parcel map. The anti-erosion measures implemented in 2022 through management agreements or small-scale anti-erosion works were taken into account. Locally, the modelled land use classes may differ from actual land use, as each modelling is only an approximation of reality. Moreover, only the input data that is available and part of the model can be taken into account.
