ResearcherID C-9892-2011
ORCID 0000-0001-6233-8478

Wissenschaftliche Interessen:

Hydrological monitoring and modelling from local to global scales

• Water storage variations in space and time from surface water bodies to the vadose zone and the groundwater
• Developing geodetic monitoring techniques for hydrological applications, in particular
  - terrestrial gravimetry with superconducting gravimeters for water storage monitoring
  - GNSS reflectometry for surface soil moisture and snow monitoring
• Satellite gravimetry (GRACE, GRACE-FollowOn) for the assessment of large-scale water storage changes
• Integration of monitoring data with hydrological models, multi-critierial calibration (for WASA-SED or for the WaterGAP Global Hydrology Model, for instance)
• Linking recent runoff and sediment dynamics with paleoflood archives
  
• Hydrological modelling of dryland areas (WASA-SED)
  
• Installation and operation of hydrological observatories (e.g., Wettzell, TERENO-Northeast, SAGOS, AGGO, TIGO)
