Ph.D. thesis, working title: "Effect of canopy-induced heterogeneity on water flux patterns below the root zone”. The work is a part of Collaborative Research Center AquaDiva.
Transformation of water and elements from the top of the canopy to below the root zone is affected by several processes varying at small scales and organized around vegetation. Canopies redistribute precipitation and create spatial variability that influences recharge, transpiration and other nonlinear ecohydrological and biogeochemical process. While canopies enhance small-scale heterogeneities, soil moisture might be equalized by root water uptake and hydraulic redistribution. I want to understand either those small-scale heterogeneities and the equalization phoneme enhance or destroy flow and matter transport into the deeper layers. By comparison water fluxes of the forest and the grassland plot of Hainich CZE, I want to explore the effect of canopy-induced heterogeneities within the forest enhance the net water fluxes.
