“…The surveys revealed that the Urbas landslide is a composite landslide (Cruden & Varnes, 1996) consisting of rock falls (upper part), deep-seated landslides (main body) and debris flow source areas (lower part) (Peternel, 2017;Peternel et al, 2017a). The long-term activity of the Urbas landslide over the past 138 years has also been reconstructed using the dendrogeomorphological analysis of bent trees (Oven et al, 2019). Dendrogeomorphology has proven to be a highly useful method in the study of past slope mass movements and has recently been applied to the analysis of the debris flood magnitude in the Planica valley (Novak et al, 2020).…”

This paper gives an overview of landslide research and the activity of landslides located above the Koroška Bela settlement in Northwest Slovenia. There are several landslides in this area and they pose a direct threat to the settlement below. The settlement is very densely populated (about 2,100 inhabitants) and has well-developed industry and infrastructure. It is built on deposits from past debris flows, indicating that large slope mass movements have occurred in the past. In this regard, the hinterland of Koroška Bela has been investigated since 2006, within the framework of various research, technical and European projects. The most extensive geological and geotechnical investigations were carried out after April 2017, when part of the Čikla landslide collapsed and mobilised into a debris flow. All of the investigations which have been carried out over the years revealed that the hinterland of Koroška Bela is characterised by high landslide activity due to geological, hydrogeological and tectonic conditions. In order to protect people and their property, it is essential to implement a holistic mitigation measure which includes remediation works (drainage works, debris flow breaker, etc.) and non-structural measures (monitoring system, early warning system, risk management, etc.). Regular and continuous monitoring of all landslides is also crucial to observe the landslide dynamics and evaluate the effectiveness of structural mitigation measures.

“…In the last decades, several site investigations and monitoring projects have been carried out in the wider landslide-prone area (Mikoš et al, 2008;Jež et al, 2008;Komac et al, 2014;Oven et al, 2019;Peternel et al, 2018;Janža et al, 2018;Jemec Auflič et al, 2019;Šegina et al, 2020).

The alpine environment is characterized by complex geology, high-energy terrain, deeply incised river valleys with high erosional potential, extreme weather conditions and dynamic geomorphic processes. Such settings provide favourable conditions for the formation of composite landslides rather than individual slope mass movement phenomena. As an example, we present the kinematics of the composite landslide Urbas in the North of Slovenia which developed in the complex geological and morphological settings characteristic of the alpine environment. The research combines several monitoring techniques and involves the integration of both surface and subsurface displacements measured in the landslide area. The results indicate that the composite sliding process consists of several simultaneous and interrelated types of movements occurring in different segments of the unstable mass that are governed by different mechanisms of displacements, such as rockfall, sliding and debris flow. The kinematic characteristics of a deep-seated landslide that formed in such conditions vary spatially, but is rather homogenuous vertically, indicating translational type of movement. Spatial kinematic heterogeneity is primarily related to the diverse terrain topography, reflecting in different displacement trends. Based on the revealed kinematic proprieties of the sliding material, the sediment discharge illustrates the sliding material balance which estimates the volume of the retaining material that represents the potential for slope mass movement events of larger scales.

“…Dendrogeomorphology has proven to be a highly useful method in studies of past slope mass movements. Oven et al (2019) reconstructed landslide activity over the past 138 years using dendrogeomorphological analysis in the form of tree ring eccentricity in the Karavanke Mountains in NW Slovenia -on the Urbas Landslide at Potoška Planina above the settlement of Koroška Bela. Novak et al (2020) developed a method that directly estimates the magnitudes of past debrisflood events on an alluvial fan using dendrogeomorphological and meteorological data sets.…”

The 2000 Stože Landslide with the consecutive wet debris flow with a volume close to 1 million m3 that hit the village of Log pod Mangartom in November 2000 had many consequences. It triggered vast efforts not only for the mitigation of the devastated area but also sparked many studies in several scientific disciplines. Various studies were performed in order to better understand this type of natural hazard and its consequences for the natural and built environment, and for society as a whole. After two decades since the disastrous event in 2000, this paper provides an aggregate survey different studies on this event performed by researchers and engineers, summarising this event’s impact on in-depth landslide research in Slovenia. The advancement in this field in Slovenia since 2000 is obvious.
