Due to the mechanisms of interception, stemflow and canopy throughfall, precipitation reaches a forest soil surface in an altered temporal and spatial distribution. The retention of water by canopies is contrasted by the formation of dynamic hotspots. Where do these hotspots evolve, and how strong are they? How do these processes impact subsurface flow processes?
Within the collaborative research center of AquaDiva, I assessed precipitation, soil moisture and environmental properties with extensive field measurements on a 1-ha mixed beech forest plot. Via geostatistical analyses, I disentangle the character and relationship of canopy and subsurface flow patterns, their impacting factors, and their potential meaning for the hydrological ecosystem functioning.
