Abstract: In this study, we focused on the Pliocene–Early Pleistocene fluvial terraces in the Velenje Basin andreconstructed the morphostratigraphy, sedimentary depositional environment, provenance and age of the graveldeposits using geomorphological, sedimentological, petrographic and chronological analyses. Geomorphologicalmapping revealed the presence of two main river‐terrace groups. The terraces in the older terrace group are severelydegraded and preserved only as remnants capping high ground, while in contrast the younger group is betterpreserved. Detailed lithofacies analyses of four selected stratigraphic sections of the older terrace group show that thegravel was deposited in a meandering and wandering environment. The gravel consists of metamorphic, igneous,volcaniclastic, clastic and carbonate lithologies derived from the north, east and west from the Paka Rivercatchments. To determine the timing of deposition, we performed isochron‐burial dating using cosmogenic 26Al and10 Be. Our new age constraints date the deposition of the older terrace group to 2.7 ± 0.3 Ma. Establishing theaggradation and incision model of the Velenje Basin documents pronounced regional tectonic uplift during thePliocene–Early Pleistocene, which led to incision and the subsequent formation of a terrace staircase.

Abstract: The Annexe 17 of the Final Report of the project LIFE Stop CyanoBloom, presenting the “Report on economic justification of the project” is composed of 14 chapters. The first part of the report gives a general overview of the cyanobacteria and their blooms, and species and toxicity of cyanobacterial toxins. With a literature review, economic consequences of cyanobacterial blooms on human health, commercial fishery, tourism and recreation, and lake monitoring and management have been evaluated. The chapter on phytoplankton and bacterioplankton monitoring options presents the importance of the phytoplankton for the lake ecology and evaluation of the water quality status. Traditional phytoplankton monitoring approaches are compared to the new monitoring options applied in the project. The chapter in-lake cyanobacterial control options give a broad review of available in-lake rehabilitation and remediation options, which can be compared with the electrochemical oxidation technique presented in the following chapter and applied in the project. According to the results obtained during the pilot testing activities, a cost evaluation of the approach has been performed and presented in the report. The last chapter gathers open issues and proposals for the further work in this field.

Abstract: Ulcinj salina is situated in the outermost southern part of Montenegro and covers slightly less than 14.5 km2 of salty basins (total surface area is 1.477 ha). The salina is 1 km from the city of Ulcinj and from the Albanian border. Ulcinj salina is located on the site of the former lagoon and wetland in the delta of the River Bojana. The works on amelioration of the former wetland area started in 1913. That is when the wetland was connected with the sea by the Port Milena channel and isolated itself from the Bojana River with a dike. In 1920 the decision to start with the establishment of the salina in Ulcinj was made. The salina was concluded in 1934 and the first harvesting of salt was done in 1935. The Ulcinj salina was created from the sea and represents a "cultural lagoon" and a man-made landscape. It is surrounded by channels that drain the nearby marshes and “knetas” (adjoining marshlands), not allowing their water to mix with the water from the salina. The channels take the water into the Port Milena canal and then into the sea. The technological process of production was upgraded in the 1970s with construction of the refinery and with attempts to expand the production, both by enlarging the territory of the salina and use of industrial production between 1984 and 1994. Yearly production of salt before the above-mentioned attempts to expand the production (in the period 1935 to 1983) was highly dependent on the weather conditions and organisation of work; a maximum of 41.240 tons of salt was produced in 1952. A combination of manually collected salt and the salt produced through industrial process in the newly constructed factory in the years 1984 to 1994 led to a maximum yearly production of 59.353 tons. By contrast, the production in the last years of production (2003 to 2013) was dramatically lower, reaching on average only around 17.000 tons per year. Ulcinj salina has very hot summers, moderately warm autumns and springs, and mild winters with temperatures only rarely below zero. On average, the most rain falls in autumn and winter, summers are two to three times more dry. Year-on-year and within years, changes in the amount of rain can be significant. Powerful pumps are essential for assuring constant water levels in basins which supports the maintenance of the ecological character of the area. The absence of salt production and consequent changes in water management have caused changes in water salinity, water regime and consequently changes in biodiversity.
