(a) Schematic representation of the semi-automated geo-electrical monitoring system, including ERT data acquisition lines installed on the dam, as well as soil moisture and temperature monitoring using Arduino-integrated sensors. The ERT lines are spaced 10 cm apart, starting from the dam crest and extending down the downstream slope. (b) Detailed view of the geo-electrical monitoring system, highlighting the electronic acquisition boards and the data recording and transmission system.
