Matarsko podolje, in SW Slovenia, is a karstic surface with many dolines, which appear between the flysch-composed Brkini hills in the NE and Mt. Slavnik in the SW. We have analyzed dolines to find ...the morphometric parameters of the depth, area, volume, and circularity index and also calculated the doline density and pitting index. All parameters were also calculated separately for individual lithological units to explain the variations of the calculated values among these groups. Morphometry was performed in GIS environment on a 1 × 1 m digital elevation model with bare earth obtained by lidar. The results show a high density of dolines (94 dolines/km
2
) and also a high pitting index (
R
p
= 8.27) compared to other studies. There are some significant differences between the measured values in individual lithologies, as the depths, areas, and volumes are largest in dolomitic beds (other beds include various types of limestones and carbonate breccia). The median values of depth, area, and volume are 2.98 m, 541 m
2
, and 690 m
3
. The circularity index is also lowest in dolomite beds and Kozina limestones; however, the differences are not so pronounced as for areas and volumes. Dolines’ longer axes are parallel to the directions of major structural elements; however, more detailed mapping should be done to confirm the influence of faults and fracture zones on the doline geometry.
Garnet is one of the most abundant heavy minerals present in the Cretaceous – Eocene flysch deposits of the Southeastern Alps and Outer Dinarides (Julian, Brkini and Istrian basins). About 300 ...detrital garnets from the Cretaceous-Eocene flysch deposits of the Southeastern Alps have been analysed by means of electron microprobe and LA-ICP-MS. In the Julian and Istrian basins, supplies are from amphibolite-facies rocks and mafic and ultramafic metamorphic rocks, while in the Brkini basin the latter are almost missing. Moreover, in the Julian and Istrian basins, supplies from skarns, very low-grade metabasites, or from ultra-high temperature metamorphosed calc-silicate granulites are present. Among these different groups, LA-ICP-MS analyses showed that trace element content can be very different in almandine-rich garnets from the different sources. In particular, the source that supplied the Julian Basin is significantly different from that of the Istrian Basin. From the Cretaceous to the Palaeocene the main supplies of Bi-type garnets derived from an area where feldspar-free garnet-bearing rocks were exposed. Successively, Bi-type garnets were supplied from an area where feldspar-garnet-bearing rocks were exposed. The presence of garnets from feldspar-free garnet-bearing rocks in the Brkini and Istrian basins can be ascribed to both recycling of material from the Julian Basin as well as direct input from the same areas that supplied the Julian Basin.
•About 300 detrital garnets have been analysed by electron microprobe and LA-ICP-MS.•Major elements allowed to define some major provenance.•Trace elements are much more sensitive than major elements and better define source rocks.
The paper focuses on the local delivery process of the LEADER programme over two programming periods (2007–2013 and 2014–2020). We tried to find out whether the LEADER method and projects implemented ...have contributed to the empowerment of the Brkini region (Slovenia), which has characteristics of a lagging and structurally weak region influenced by peripheralization processes. Quantitative and qualitative analysis of LEADER projects underlined that the Brkini region was quite successful in
different actors and sectors in joint projects and establishing cooperation between stakeholders. Cooperation is reflected in (1) partnerships and networking between existing and new actors and stakeholders, (2) LEADER funds being mostly used for “smaller projects” and networking within the region, (3) the synergies between LEADER and existing local aspirations as it supports several areas of the multi-sectoral approach (i.e., tourism promotion, agricultural production and processing), (4) enhanced recognisability and promotion of the Brkini region at sub-regional, regional, national and cross-border levels. In the context of
t, we were able to identify some incentives, but also some bottlenecks (local clubs/societies/associations lack institutional, administrative and financial capacity, etc.). Decision-makers should pay special attention to this and also promote a culture of reflexivity when preparing new animation strategies for the next programming period.
Rainfall kinetic energy–intensity relationships for rainfall erosivity estimation were established on the basis of raindrop size distribution measurements performed in the Brkini hilly area in ...southwest Slovenia, a transitional area between the Mediterranean and continental climate conditions. A set of measurement instruments, an optical disdrometer coupled with a rain gauge, was installed on two locations: Koseze and Kozjane. The data set contained raindrop size distribution and rainfall intensity measurements of the rainfall events that occurred during a one-year period in the 2008/2009 season. The rainfall intensities obtained with the rain gauges were used for event rainfall depth control measured by the disdrometers and testing the established kinetic energy–intensity (
KE–I) relationships. Two exponential
KE–
I relationships were established for each measuring site, for 1-min and 5-min rainfall intensity data, respectively. Their performances were tested and compared with the performances of other
KE–
I relationships proposed by authors throughout the world, which could be recognised as relatively suitable for kinetic energy estimation in the Mediterranean area. The comparison included 11
KE–
I relationships expressed with linear, linear-log or exponential formulations. The analyses exposed the rainfall intensity overestimation by the disdrometers and the limited use of the tipping bucket rain gauge for kinetic energy estimation under such climate conditions. According to our results, the established
KE–
I relationship for 5-min intensity data in Koseze is recommended to be used while estimating rainfall kinetic energy in the Mediterranean part of Slovenia. As input data, rainfall intensities measured with precise weighing rain gauges, as those installed in the Slovenian meteorological network, should be used. However, when using rainfall intensity data obtained with a tipping bucket rain gauge of lower accuracy or insufficient intensity range, the exponential relationship of
Coutinho and Tomás (1995) is expected to deliver better kinetic energy estimations.

This article presents cultivated terraces as social and economic landscape elements that are closely connected with natural conditions. The theoretical part, which presents some of the professional ...activities connected with terraced landscapes and examples of studying them around the globe, is followed by a detailed presentation of the features of the unique terraced landscape in the Brkini Hills, Slovenia. Its features, changes, and development trends are placed within the context of the natural features of the area studied, especially its relief conditions and aspect, as well as unfavorable demographic characteristics and modern agricultural trends. Despite modern mechanized farming, the remaining farmers are finding it increasingly more difficult to maintain the cultural landscape. The former tilled terraces were converted into meadows decades ago. Many terraces are being overgrown. Afforestation threatens the future existence of cultural landscapes and affects their development potential and significance as a cultural value.

The classical Karst transboundary aquifer is a limestone plateau of 750 km2 that extends from Brkini hills in Slovenia to Isonzo River in Italy. For 20 years, and especially in the last two years, ...the Mathematic and Geosciences Department of Trieste University has run a monitoring project in order to better understand the groundwater hydrodynamics and the relation between the fracture and conduit systems. A total of 14 water points, including caves, springs and piezometers are monitored and temperature, water level and EC data are recorded. Two sectors are highlighted: the southeastern sector mainly influenced by the sinking of the Reka River, and a northwestern sector connected to the influent character of the Isonzo River. Water table fluctuations are significant, with risings of > 100 m. During floods most of the circuits are under pressure, and only a comparative analysis of water levels, temperature and EC permits a precise evaluation of the water transit times in fractured and/or karstified volumes.
