Short presentation

Research areas:

Combined use of cross-borehole electrical resistance tomography and ground penetrating radar

• Visualize water infiltration in the unsaturated zone (Looms et al., 2008b; Haarder et al., 2012)
• Estimate unsaturated hydraulic parameters at meter-scale (Looms et al., 2008a; Scholer et al., 2012; 2013)
• Recharge estimation (Haarder et al., 2015)
• Monitor gas migration in saturated zone (Lassen et al., 2015; Yang et al., 2015)

 Cross-borehole ground penetrating radar

• Characterize porosity variations in chalk (Nielsen, et al., 2010; Keskinen et al., 2017)
• Delineate sand occurrences in clayey till (Looms et al., 2018)
• Improving inversion strategies (Hansen et al., 2008; 2013a; 2013b; Cordua et al., 2008; 2009; Looms et al., 2010)

 Reflection ground penetrating radar

• Monitor forced infiltration into unsaturated sand (Haarder et a., 2011)
• Delineate organic matter at lake-bottoms (Nilsson et al., 2009; Kidmose et al., 2011)

 Cosmic-ray neutron detection

• Compare model results to field data (Andreasen et al., 2016; 2017b)
• Estimate biomass and interception using thermal and epithermal measurements (Andreasen et al., 2017a)
• Analyze temporal stability of soil moisture at various land cover types
