Sprinkling Experiments
In May, we ran sprinkling experiments on a hillside in Freiburg to observe how water moves beneath the surface during storms. We used special “heavy” water (Deuterium) to trace its path through the soil. At the final Watson Cost Action project conference, I shared our first findings: water traveled through the soil in just 20-40…

Video: How we take soil samples for soilwater analysis
For my PhD thesis we will drill 500+ holes and take over 6000 soil-samples. Here you see our process:

Field Campaign in the Alps
The final field campaign took us to the most scenic but also coldest and steepest catchment of our research project. We spend the last September weeks in the “Padaster”-Catchment close to Innsbruck in Austria. Our first day started with a snowy greating and clouded mountains, however the sky cleared and sunshine revealed the most atonishing…

Field Campaign Sauerland
The last week of July was the fieldcampaign in Sauerland where we also dug three trenches for Subsurface Flow Measurement. This time we chose a mixed forest, clearcut and pasture site. Upslope of the trenches we also drilled soilcores and sampled eDNA, water-soluble organic carbon and water stable isotopes in different soil layers. Per Trench…

Field Campaign Freiburg
Last Month I started my Phd in the DFG funded “Research Unit Subsurface Stormflow” with a joint Field Campaign. We excavated multiple trenches and installed drainage-mats. Flow caught on these mats funnels into pipes which will run into tipping buckets, allowing us to measure subsurface flow amounts. To monitor subsurface flow on the catchment scale,…
