Remote sensing

Surface movements are captured using active and passive remote sensing techniques. The study site’s surface is captured periodically using a Riegl VZ6000 laser scanner. In addition, unmanned aerial vehicle (short, UAV) flights are performed occasionally, depending on weather conditions and vegetation height. Remote sensing datasets are used for time series analyses and change detection. The comparison of different datasets from multi-temporal surveys enables the quantification of movements between the selected periods and thus the assessment of displacement rates over time. Moreover, it also allows to roughly describe and define the geomorphological processes that characterize the landslide dynamics.

Meteorological station

The study site is further equipped with a Campbell meteorological station which has been in operation since September 2022. The station records different climatic parameters, that are considered of major importance for landscape evolution. Among these, temperature [°C], humidity [%], solar radiation [W/m²], wind speed [m/s] and precipitation [mm] are recorded every 5 minutes and then transmitted to the server in Vienna. All data can be accessed via the webpage in real-time.
