Since the old erosion measurement weir at monitoring site E1 had become somewhat outdated, it was high time to install a new one.
On March 18, 2025, a new H-flume made of stainless steel was successfully installed. It is intended to help determine the amount of eroded material being transported by the water flow.

In order to allow turbidity measurements during surface runoff events again, a new measuring chamber was installed directly after the outlet of the 400 l/s H-flume, using the old turbidity probe.

The old radar sensor was also reused and recalibrated for water level measurements.

This setup should now once again make it possible to obtain reliable results during heavy rainfall events, thereby gaining more insights for soil protection and the prevention of environmental damage.
