  • Hidrogeografski izzivi upravljanja z vodnimi viri v občini Loški Potok [Elektronski vir] = Hydrogeographical challenges of water resources management in the municipality of Loški Potok
    Trobec, Tajan
    The Municipality of Loški Potok is part of the Dinaric Karst and the Black Sea Basin. Due to the predominance of permeable rocks and karst terrain, there is almost no surface flowing water. The ... exceptions are the Malenščica and Čabranka rivers, which in the past powered many water-driven mills and sawmills. Today, the Malenščice spring is tapped for the central water supply and a small hydroelectric power plant has been built on the Čabranka. The water from the Loški Potok area flows mostly underground in various directions (south to the Kolpa river basin, east and north to the Krka river basin, and west to the Ljubljanica river basin). Due to the few tracing experiments and proven underground bifurcations, the Loški Potok area is relatively poorly studied hydrologically. In addition, there are no functioning gauging stations in the municipality, which further complicates the interpretation of discharge characteristics and the assessment of water resource availability. An important hydrological element of the studied area is the numerous karst springs that were used by the inhabitants for various purposes (water supply, watering livestock, washing, watering, etc.). Many of the springs were deepened, walled, provided with steps or otherwise improved. Almost every settlement also had at least one karst pond, mainly for watering livestock. They also used rainwater for water supply. Although they no longer serve their original purpose today due to the construction of the modern water supply network, these traditional water resources represent an important »Kras. Voda. Človek.« DUGS »Karst. Water. Human.« 46 cultural and historical element of the region and a potential for the development of sustainable tourism. During extreme rain events, flooding can occur in the Retijska uvala and Travniško polje areas, threatening agricultural land and many low-lying houses and other buildings. In the event of potentially increased flood risk due to climate change, it will be necessary to adapt to flooding by preventing construction in flood-prone areas and taking other self-protection measures. The prevailing karst terrain with limited neutralisation and self-purification capacities makes the area of the Municipality of Loški Potok extremely vulnerable to any anthropogenic pollution. This is all the more important because water from the area flows through extensive underground connections towards the low-lying karst springs outside the municipality, some of which are important for the water supply of the local population. It is therefore no coincidence that 43% of the municipality's territory is protected by water conservation areas. Fortunately, pressure on water resources is relatively low, as the municipality is dominated by small settlements and is sparsely populated. Probably the biggest challenge is the unfinished sewage network. However, the actual impact of anthropogenic pressure is difficult to assess, as the quality of flowing surface water is monitored only at the Čabranka River, and the quality of groundwater at some karst springs outside the municipality, to which water from Loški Potok is discharged.
