Flow map (multiple streamlining)
Description
The flow map with multiple 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 the flowing water that arrives in a pixel proportionally to all lower surrounding pixels, with the lowest pixel receiving the most runoff and the lowest pixel receiving the least runoff (Multiple Flow Direction). This creates diffuse run-off lines that give a more realistic picture of run-off over a slope. The map is especially useful in case of relatively flat or strongly divergent topography, and on wide homogeneous slopes. The flow map is based on the digital height model and the Flemish Hydrographic Atlas.
