Pressure sensors in streams and lakes

For the monitoring of surface water discharge, we will install pressure sensors in the streams that drain the selected sub-catchments. This requires some previous field work: firstly, we need to find sites that are both suitable for the installations; secondly, we need to carefully take the dimensions of the stream and measure the flow discharge at the selected location.

Measure the groundwater level

To measure the groundwater level, we will install pressure sensors in existing groundwater wells (mostly from the LfU). We will focus on those wells with filters located within the first aquifer complex (GWLK 1), since this is mainly unconfined and thus linked to the hydrological cycle.

Climate stations

To generate climate data, we will install one climate station in the north of our catchment (where the selected sub-catchments will also be located). Here we will monitor precipitation, temperature, wind speed, solar radiation, etc. We will also make use of the data provided by the handful of stations from the DWD in the region and, to increase climate data density, we will contact private climate stations owners to ask for access to their data.

Soil moisture sensors (TDT type)

Finally, we will install soil moisture sensors (TDT type) in the sub-catchments. These will be installed at different depths along the soil profile and in different types of soils.


We would like to study infiltration dynamics and estimate groundwater recharge in our catchment area, and see how these processes could be affected by the projected impacts of climate change as well as water management strategies. The input data required to run the simulations is not always available (e.g., in our case, we are aiming at having daily temporal resolution), which means that we have to the generate the data ourselves. This is when the field experiments come into play.
