Solution scenario for erosic bottlenecks — line measures

The map with solution scenarios for erosic bottlenecks contains the data from the municipal erosion plans in Flanders, approved by the Department of Land and Soil Protection, Underground, Natural Resources of the Flemish Government. The data from these plans are proposals for measures to combat erosion which are considered useful. The inclusion of measures in these plans does not mean that the measures will actually be implemented. Since not all erosion-sensitive municipalities have an approved municipal erosion control plan, the map cannot be considered complete. It is estimated that around 120 municipalities in the Flemish Region are affected by water and processing erosion in at least part of their territory due to the combination of the sloping topography, the high soil loam content and agricultural practice with intensive arable farming. In Flanders, these municipalities are concentrated in an average of 30 kilometres in the south of the Region. About 100 municipalities have an approved erosion plan. The municipal erosion plan consists of, on the one hand, the study of historical and environmental factors (the analysis of the preconditions), and on the other hand the identification of erosic bottlenecks together with a concept of solution consisting of a combination of source-oriented and symptom-oriented erosion control measures for each of the bottlenecks (the bottleneck analysis). A bottleneck is defined as the area that drains to a known erosion problem point. The plans submitted for approval were drawn up by ten different study agencies. For this map, the variety of naming and symbology of erosion measures was reduced to ten classes of measures, divided between point, line and plane measures. The data layer “line measures” contains the proposed measures that can be represented as a line (e.g. dams, grass buffer strips, grass corridors, buffer moats and small landscape features).
