Research

For my PhD thesis I performed intensive field campaigns for measuring and modelling of macropore flow from plot scale to catchment scale. The results of which have led to a concept of macropore influence on hillslope hydrological functioning as well as an analysis of spatial variability in local infiltration patterns and the use of field infiltration patterns for the parameterisation of macropore flow in a physically based model.

Currently I am working on linking spatio-temporal earthworm distribution models with a preferential flow model to obtain an integrated ecohydrological model: http://brandenburg.geoecology.uni-potsdam.de/users/schroeder/biopore/home.html
