Our research focuses on ecohydrological processes at interfaces between aquifers and surface water bodies. Due to the mixing of these two different types of water bodies, steep biogeochemical gradients characterize the mixing zone and allow a variety of processes along these gradients. We investigate hydrological transport processes, biogeochemical turnover and the close coupling of these processes at the interface.

Our overall objective is to improve the understanding of ecohydrological processes at interfaces in order to provide a scientific basis for the restoration of rivers and lakes and to support decision-making in water management. We carry out field, laboratory and modelling studies. One focus is on the development and application of innovative measurement techniques.

We study three different types of groundwater-surface water interfaces:

  1. Currently the main research focus is on so-called hyporheic zones (streambed, i.e. interface between stream and aquifer). We consider the hyporheic zone as a natural, hydrodynamically driven bioreactor responsible for the impressive self-purification capacity of streams regarding nutrients (phosphorus, nitrogen, and carbon) and organic trace compounds (e.g. pharmaceuticals). Sometimes is is also called a river's liver. More in this podcast (in German):

  2. Other research of our multidisciplinary group focuses on lakebeds, i.e. aquifer-lake interfaces. Surprisingly, lacustrine groundwater discharge into lakes has usually been neglected in water and nutrient budgets of lakes until recently. Even world-wide there is very little research on this topic. We could show the large relevance of groundwater exfiltration and groundwater-borne nutrient transport for lake eutrophication and other ecological challenges.

  3. Further research focuses on burrowing macrozoobenthos (chironomid larvae) in lake sediments (bioturbation). These small ecosystem engineers alter not only the local hydrology and biogeochemistry but have even severe impacts on entire ecosystems.

Our topics in the framework of the department

The departmental core area "Landscape-waterscape interactions" is mainly addressed with research on the 2nd interface (catchment-lake interactions) and additionally with some research on the 1st interface (catchment-stream interactions). The departmental core area "Urban ecohydrology" is mainly addressed with research on the 1st interface (hyporheic zones in urban streams) and additionally with some research on the 2nd interface (lacustrine groundwater discharge in urban areas). The departmental core area "Aquatic-biotic coupling" is addressed with research on the 3rd interface which is created and maintained by burrowing macrozoobenthos.
