The study of tourism carrying capacity in the municipalities of Tolmin, Kobarid and Komen has shown that the infrastructural and economic carrying capacity is the most problematic, as most indicator limits are already exceeded in the summer season. The most favourable is the spatial-ecological carrying capacity, where none of the studied indicator limits were exceeded. The results of the carrying capacity assessment for tourism in these municipalities should not be used as a tool to restrict tourism development, but rather as expert recommendations to promote more sustainable tourism development. Infrastructure identified as deficient cannot be improved immediately. Improvements require large financial investments that municipalities are not able to ensure quickly. We need a tourism development strategy that, in addition to all the necessary improvements, comprehensively addresses the problems that municipalities face from overtourism, especially during the high season.

Geomorphological and geological mapping have long been used to study the glacial history of the Slovenian Alps, but many uncertainties remain regarding the time and extent of Pleistocene glaciations there. Glacial landforms and undisturbed glacial deposits are rare in the areas of the former glacier terminus, especially in the Soča Valley, where large discrepancies in the interpretation of the extent of the former Soča Glacier have been reported. Early studies proved inconclusive as to whether one or two glaciations extended into the Soča Valley as far as Most na Soči. In order to answer this question, the Quaternary sedimentary succession and landforms in the Modrejce Valley near Most na Soči were investigated. New geological and geomorphological field data allow the interpretation of the sedimentary environment and the stratigraphic relationships between different units. In response to glacial dynamics, the sedimentation developed from glaciofluvial and glaciolacustrine to fully glacial environments, followed by slope deposition. At higher altitudes lateral moraines are preserved, while the staircase-like slope below has been carved into older glacial, glaciofluvial and glaciolacustrine deposits by glacial and post-glacial processes, including fluvial erosion and slope dynamics. We conclude that the succession studied here was deposited over the course of two different glacial advances – LGM and pre-LGM. Our study thus suggests that the Soča Glacier extended as far as the area of Most na Soči twice over the course of the late Quaternary.

An entirely preserved large specimen of Upper Cretaceous rudist Psedopolyconites slovenicus n. sp. is described,characterized by the low and broad lower valve surrounded by a thick envelope of tiny straight tubules. The specimenwas redeposited in Paleocene from the northern edge of Adriatic-Dinaric carbonate platform into a marginalpart of the flysch basin.

Carbonate component prevails substantially over the silicate within the Quaternary detritial lacustrine sedimentary sequence sampled in the abandoned clay-pit in Srpenica, NW Slovenia. Sampling was done discriminately among dark and light laminae. Cluster analysis and other statistical methods of geochemical data interpretation from these samples show that dark gray laminae contain significantly more of the silicate componentand some heavy metals (Ni, Cu, Co, Zr) compared to light gray laminae. The differences in geochemical and mineral composition are the cause of lamination of this lacustrine sediment sequence. Moreover, the dark gray laminae are coarser - grained. Lamination is thus conditioned by changes in the in flow pattern of the detritial material from different source areas and not by seasonal sedimentary cycles.

We conducted a phytosociological study of the communities hosting the rare and endangered fern Adiantum capillus-veneris in the foothills of the Julian Alps, in Karst and in Istria. Based on a comparison with similar communities elsewhere in the southern Alps (northern Italy) we classified most of the recorded stands into the syntaxa Eucladio-Adiantetum eucladietosum and -cratoneuretosum commutati. Releves from the southern Julian Alps, located in comparatively slightly colder and moister local climate and the dolomite bedrock are classified into the new subassociation -hymenostylietosum recurvirostri subass. nova. Stands with the abundant occurrence of the liverwort Conocephalum conicum, are classified in to the new subassociation -conocephaletosum conici subass. nova. Stands in conglomerate rock shelters along the Soča at Solkan are classified into the new association Phyteumato columnae-Adiantetum ass. nova, a community of transitional character between the classes Adiantetea capilli-veneris and Asplenietea trichomanis.

The Soča river is one of the most beautiful Alpine rivers. Its green colour, gorges and cascades and surrounding landscape attract many tourists and water sports enthusiasts. However, the use of the river for kayaking, rafting and similar activities depends mostly on water height and flow, which can change very quickly. In such cases it is essential to keep potential river users informed about the situation, about the possibility of activity in case of low water or about possible dangers in high water time. At the moment, the decision about activities on the river can be made only by observing the river level at some specific points and upon experiences. To enable more relevant information about the river status a 3D model of one of the most attractive sections of the river Sočawas prepared. The model is based on official topographic data (DEM, orthophoto) and field GPS measurements. It gives a very detailed presentation of the river basin, with all prominent rocks, cascades and river banks. Changing water levels in the model enable visual simulation of the situation. For the future the idea is to include real time water level measurement and to calculate hydraulic behaviour of the water in the river basin. Such simulation would enable almost real time predictions of the river situation. They can be used by river authorities to balance activities on the water. [ABSTRACT FROM AUTHOR]

Deciphering deformation mechanisms within Quaternary sediments in a highly dynamic environment such as the southeast European Alps is often a challenging task that requires the use of a variety of methods. Due to the geohazards involved, the interpretation of deformation mechanisms can have a major impact on society and may enable the preparation of appropriate engineering solutions. We present an example of how deformation structures can be studied by integrating geomorphological, sedimentological and structural geological mapping using photogrammetric and leveling surveys, paleoseismological techniques, optically stimulated luminescence dating and ground penetrating radar surveys. Quaternary deposits on the slopes of the formerly glaciated Soča Valley near Most na Soči are tilted and dissected along numerous faults within the deformation zone of the Idrija Fault, a large, active, dextral strike-slip fault. Reconstruction of deformation history indicates that at least five deformation events occurred during deposition of the glaciofluvial succession interbedded with glaciolacustrine deposits, dated to Penultimate Glaciation. Ground penetrating radar profiles and outcrop observations reveal NE – SW striking faults, which are approximately perpendicular to the primary Idrija Fault. Based on the local geologic setting, we considered glaciotectonics, gravitational faulting due to ice-decay collapse or slope instability, and tectonic faulting as possible deformation mechanisms. Based on detailed documentation and analysis of the geometry and kinematics of the deformations, we interpret the observed deformations as secondary structures that result from paleoseismic activity of the Idrija Fault, and some structures resulting from glaciotectonics and gravitational faulting. The transtensional type of deformations at the studied site shows the local character of the main fault, which occurs here due to geometrical and kinematical changes of the Idrija Fault causing local transtension in the Most na Soči area. The complexity of the fault and the first paleoseismic evidence dating back to Penultimate Glaciation provide valuable new data for understanding the seismic hazard in the region. • Origin of deformations within Quaternary sediments in a highly dynamic environment unraveled. • Glaciofluvial and glaciolacustrine deposits record recurrent faulting and non-tectonic deformations. • First paleoseismological evidence on the major Idrija Fault extending back to Penultimate Glaciation. • Local scale fault complexities reflect fault geometric and kinematic changes.
