“…1). The Lake Skadar is the largest lake on the Balkan Peninsula and is located in the area of Dinaric karst, with a surface area that seasonally fluctuates between 370 and 600 km 2 (Pe sić et al, 2018) The lake is well-known for the occurrence of numerous karstic springs (Radulović et al, 2015). Most of them are rheocrene and limnocrene springs.…”

The aim of this study was to reveal faunistic and diversity patterns and to assess the effects of environmental factors on the differentiation of leech communities. This study covers investigations of 82 karst springs in Montenegro from 2009–2017. The communities were analyzed in respect to five wellspring types – caves, sublacustrine, limnocrene, rheo-limnocrene and rheocrene. The percentage of substrate types and aquatic vegetation cover was recorded alongside water parameters. In total, 18 leech species were identified, of which two were recently described as new species for science (Dina minuoculata Grosser, Moritz and Pešić, 2007 and Glossiphonia balcanica Grosser and Pešić, 2016). K-means clustering was used to classify leech assemblages into three homogenous groups. The patterns of leech communities and the components of both alpha and beta diversity were examined in identified groups of assemblages. The significance of environmental factors and the impact of selected factors were assessed through forward selection analysis, CCA and RDA. Our results indicate that the type of spring and the environmental variables, as well as the combination of biotic and abiotic factors in a microhabitat dictate the distribution of leeches.

“…The average annual precipitation on the area is relatively high (approximatively 2500 mm/year of which 80-85% of rainfall occurs between November and March [14]) due to its geographical position in relation to the Adriatic Sea and its terrain configuration. Despite that, there is no abundant surface water on this area neither a well-developed hydrographic network [15]. Almost all rainwater infiltrates rapidly into the permeable ground, percolating vertically until the water table, and the surface drainage network is poorly developed (limited to the abovementioned situations), with a small number of local watercourses that flow only in the rainiest period of the year [9].…”

“…In addition to these, a third aspect must be considered: The lake is drained by the Buna River, just southward the city, and after few kilometres it receives the Drin River along the hydrographic left. The Drin River is the longest river of Albania (average flow rate of 360 m 3 /s, drainage basin of about 14,200 km 2 , length of 285 km out of a total of 335 km; [26]) and its flow rate, besides inducing floods in the southern plains [27], can create a hydraulic barrier for the waters that move out from the lake [12,15] up to induce flow inversions. This is a real possible scenario in case of very high-water tables originated by the natural flooding of the Drin or as consequence of extraordinary opening of the upstream dams during the management of very high-water levels [24].…”

Detection of Seasonal Inundations by Satellite Data at Shkoder Urban Area, North Albania for Sustainable Management

The European Space Agency satellites Sentinel-1 radar and Sentinel-2 optical data are widely used in water surface mapping and management. In this work, we exploit the potentials of both radar and optical images for satellite-based quick detection and extent mapping of inundations/water raising events over Shkodër area, which occurred in the two last years (2017–2018). For instance, in March 2018 the Shkodër district (North Albania) was affected twice by the overflow of the Drin and Buna (Bojana) Rivers and by the Shkodër lake plain inundation. Sentinel-1 radar data allowed a rapid mapping of seasonal fluctuations and provided flood extent maps by discriminating water surfaces (permanent water and flood areas) from land/non-flood areas over all the informal zones of Shkodër city. By means of Sentinel-2 data, two color composites maps were produced and the Normalized Difference Water Index was estimated, in order to further distinguish water/moisturized soil surfaces from built-up and vegetated areas. The obtained remote sensing-based maps were combined and discussed with the urban planning framework in order to support a sustainable urban and environmental management. The provided multi-temporal analysis could be easily exploited by the local authorities for flood prevention and management purposes in the inherited territorial context. The proposed approach outputs were validated by comparing them with official Copernicus EMS (Emergency Management Service) maps available for one of the chosen events. The comparison shows good accordance results. As for a further enhancement in the future perspective, it is worth to highlight that a more accurate result could be obtained by performing a post-processing edit to further refine the flooded areas, such as water mask application and supervised classification to filter out isolated flood elements, to remove possible water-lookalikes and weed out false positives.

“…Elevation map of the study area with sampling locations for collecting precipitation (P1 and P2), Mareza spring water (S1, S2, S3, and S4), and surface water of the Zeta River (upstream, RU; downstream, RD). recharge area of the Skadar Lake karst aquifer is spread over a wide area in the karst plateaus, while the discharge area extends along the karst depressions and deep canyons [36]. According to the Institute of Hydrometeorology and Seismology of Montenegro's (IHMS) meteorological data, the mean monthly air temperature during the sampling period (from February 2017 to March 2018) in Podgorica was between 7.3 • C in December and 30 • C in July and August ( Figure 3).…”

The Mareza karst aquifer is the most important drinking water resource for the water supply system of the City of Podgorica, the capital of Montenegro. This study presents the first assessment for the determination of the Mareza catchment area. Water chemistry and stable isotopic composition (δ18O and δ2H) of monthly precipitation samples (as inputs) are presented, in order to determine the Local Meteoric Water Line (LMWL) for the study area, and to analyze the behavior of the karst spring Mareza (as output) and the Zeta River water. The possible impact of the river on the Mareza springs was also investigated. Stable isotope compositions were used to analyze the origin of the four springs of the Mareza aquifer. Seasonal variations of δ18O and δ2H values and deuterium excess (d excess) changes in precipitation are explained by the mixing of air masses, such that a Mediterranean source prevails in the winter period, while in the summer period, the area is rather under the influence of air mass originating from the Atlantic Ocean. All spring water samples have lower δ values than the local precipitation and they plot above the LMWL, which may indicate recharge at a higher altitude in the distant mountainous area. The d excess values of all water samples (higher than 10‰) indicate the prevalence of the Mediterranean as a moisture source. Based on the analysis of the seasonal variations of δ18O and δ2H in precipitation and the Mareza spring, it has been estimated that the groundwater mean transit time (MTT) is 92–129 days, and that the young water fraction (Fyw) amounts to 40.9%–53.3%. These values are typical for the strong karstic springs of highly karstified terrains.
