A prototype of a low-cost GNSS (Global Navigation Satellite System) monitoring system was installed on a deep-seated landslide in north-western Slovenia to test its performance under field conditions. The system consists of newly developed GNSS stations based on low-cost, dual-frequency receivers and open-source GNSS processing software. The detected surface displacements were evaluated through a comparison with the network of classic geodetic measurements. The results of a nine-month monitoring period using seven GNSS stations provided a detailed insight into the spatial and temporal pattern of deep-seated landslide surface movements. The displacement data were correlated with precipitation measurements at the site to reveal how different parts of the landslide react to rainfall. These data form the basis for the further development of an early-warning system which will help to manage the risk the landslide poses to the local population and infrastructure.

The principal aim of this study is to form a basis to predict real-time dynamics of landslides that have been posing a direct threat to settlement Koroška Bela (with approximately 2200 inhabitants) for centuries. Prediction modelling is based on monitoring and recognition of displacement triggering mechanisms and their interactions. The study area is located above the settlement of Koroška Bela (NW Slovenia, Karavanke) which exhibits a number of deep-seated landslides (the Urbas and Čikla landslides) in weathered siltstone and claystone.

Climate change is expected to affect the elements of the hydrological cycle, which are also related to the landslides and debris flows triggering mechanics. In the scope of this contribution, we evaluated climate change impact on the water balance components in the hinterland of the Koroška Bela (NW Slovenia), which is one of the endangered settlements in Slovenia. For this purpose, we focused on the representative concentration pathway (RCP) RCP4.5 scenario, which can be described as a midway scenario. Lumped conceptual hydrological model was used in order to model the relationship between the hydrological cycle elements. Moreover, climate change impact on the intensity-duration-frequency (IDF) curves was also estimated. The results indicate that total rainfall as well as effective rainfall could increase in the future. Moreover, hydrological model results indicate a possible surface runoff increase from the Bela stream catchment.
