Landscape Controls on Hydrological Responses to Changing Climate Conditions

In this research project, I investigate to what extend landscape characteristics (e.g., topography, land cover, size or geology) play a fundamental role for the sensitivity of a catchment to changing climate conditions. A diagnostic approach is used, which considers major behavioral catchment functions by using hydrologically relevant signatures. First results of this study suggest that neighboring catchments that look rather similar at first sight can have a significantly different hydrological response to the same changes in external climate conditions. This indicates that differences in spatially distributed physical catchment characteristics are not only of great importance for current streamflow behavior, but also play a major role as first-order controls for the sensitivity of catchments to changing climate conditions in the boreal zone.
