Flow map (single streamlining)

The flow map with single streamlines shows the lines in the landscape where the water flows potentially concentrated after a rain shower, taking into account the topography and the watercourses present. The colorization shows the size of the catchment area to the pixel per pixel of 5m*5m (in ha). The calculation algorithm directs all the flowing water that arrives in a pixel to the lowest surrounding pixel (Single Flow Direction). This creates concentrated, clearly defined drainage lines that represent the locations in the landscape with the most chance of drainage. The flow map is based on the digital height model and the Flemish Hydrographic Atlas.
