The interaction between groundwater and surface water is measured using the iFLUX digital sensors.
We are measuring inside the river, with 2 vertical sensors, and we are using 2 horizontal sensors to measure the interaction in the surrounding valley.

The horizontal sensors are each installed in a different layer of the subsoil, one in the peat layer and one in the sand layer.

This setup will stay from mid-October till the end of February while the sensors sent their data through a gateway for remote data access. The measured flux data will also be linked to the measured hydrologic variation.
This study enables us to further optimize the iFLUX digital sensors and adds knowledge that will improve further applications.
The data will be compared to other measuring techniques to calibrate the groundwater model.
The results of the study are still being processed. Nevertheless, we have already been able to take steps forward in terms of sensor design, but also in terms of installation into the water and in the field.
Partners in this study are: University of Antwerp (Ecosystem management group), Warsaw University of Technology, Warsaw University of Life Sciences, iFLUX NV
