The conceptual hydrogeological model of the Plitvice Lakes

A conceptual hydrogeological model of the Plitvice Lakes National Park reveals that the park's unique karst landscape is sustained by groundwater flow from the Mala Kapela mountain area and runoff directed toward the Black Sea basin. The system relies on poorly permeable Triassic dolomites acting as natural barriers, which regulate water flow to create the iconic lakes and waterfalls. Lakes Prošćansko and Kozjak play a crucial role in maintaining high water quality throughout the park. However, the model also highlights a vulnerability: water from Lake Kozjak and the Lower Lakes can sink underground along a fault line, posing risks if natural functioning is disrupted. This study integrates geological and hydrological data to provide insights into the dynamic balance of this fragile ecosystem.
