Research Interests

Interaction between groundwater and surface water in the hyporheic zone and development of novel in-situ measurement techniques

  • statistical time-series analysis of continous aerobic respiration and other hydrological data obtained from a gravelly 3rd order stream
  • deriving of time-variant aerobic respiration rates in the hyporheic zone by combining continuous EC and O2 measurements
  • development of a planar-optode based method for the in situ measurement of vertical oxygen profiles in gravelly streambeds

Time lapse videos from our research area


Selke at February 2012. Anchor ice, Selke is freezing up completely.



Measurements of stream level and oxygen concentration in the streambed around a gravel bar (at 45 cm depth). In Vieweg et al. (2016) we could show, how the differences in oxygen concentration are a consequence of different travel times in the streambed. The frequent stream level changes are induced by an upstream water mill.



Two separate flood events occured at the Selke between March and June 2013. The snow melt resulted in a first flood from 11th April (at 0:28) with a peak discharge of 15 m³/s. Extreme weather conditions caused a second flood starting by the end of May (at 1:25) with a discharge over 25 m³/s. The mean discharge of the Selke is 1.5 m³/s.
