Research Objectives

Develop a multi-scale thermal imagery method, where airborne and ground-based methods can quantify where, when, and how much groundwater escapes to stream valleys with special attention to how temperature-controlled changes in hydraulic parameters affect water storage/wetness/flooding/upwelling and direct seepage to streams. The innovative aspect is to investigate if thermal imaging is a feasible method for mapping upwelling at the scale of stream networks and linking these to temporal changes in hydraulic parameters and possible hot-spots of reactivity.

Tasks and methodology

  • Instrument Holtum stream (Denmark) sites and perform seasonal campaigns with airborne and ground based methods.
  • Create local 2D/3D flow and heat transport models to understand flow upwelling processes.
  • Test the imaging and modelling techniques at TERENO sites in Germany.
  • Integrate knowledge and data from local models into a 3D sub-catchment model.


Data produced during the research project will be inserted in the HOBE database.
