Measurement of water levels in the water table

Hydrogeological monitoring

 

Piezometer, positioned here and there in the Bauerngrundwasser and the artificial channel, continuously measure variations in level in the water table. Coupled with water level (limnimetry) and flow (measurement) data, it was possible to quantify exchanges between the water course and water table for the entire island (infiltration and exfiltration zones). A slight draining of the water table in the Bauerngrundwasser has already been highlighted.
