New pressure sensors for measuring water levels at Asa

This spring Asa Research Station has installed new water pressure sensors at the SITES water monitoring locations and the streams in the surrounding catchment areas. By measuring the pressure in the water it is possible to calculate the water level and the discharge. This type of data has already been collected for many years in Asa, but these new sensors are capable of sending the data directly to an online server which gives researchers immediate access to data from the office. This makes it easy to track the effect of sudden events such as heavy rainfalls and periods where changes in water level are expected, for example in early spring when the snow melts or during drought periods.
