Research Topics

Groundwater resources in Germany (under climate change)

  • determination of available amount of groundwater
  • groundwater as safe future baseflow generator?
  • developing large-scale 3D hydrogeological facies models
  • finding proxies to cal/val large-scale numerical flow models (e.g. groundwater age, hydrochemical ratios)

Groundwater-surface water interactions on a large scale (Elbe River)

  • determination of hydrochemical/isotope indicators to detect groundwater input
  • modelling groundwater inflow
  • groundwater age distribution in riparian aquifers

Long-term impact of 2018-2020 drought period in the Harz Mountains

  • soil moisture under variable reforestation schemes
  • changing hydrological patterns on affected areas
  • long-term changes in amount and composition of groundwater recharge

Regional analyses of event runoff features and causes
