visszáfolyósítási

Visszafolyósítási refers to the process of river restoration in Hungary, specifically focusing on re-establishing natural water flow patterns and ecological functions. This concept emerged as a response to decades of river regulation and channelization that significantly altered Hungarian rivers, leading to a decline in biodiversity and a loss of natural hydrological processes. The primary goal of visszafolyósítási is to undo the negative impacts of these past interventions.

Key aspects of visszafolyósítási include reconnecting floodplains to river channels, allowing for natural inundation and the creation of diverse aquatic and semi-aquatic habitats. This often involves removing artificial barriers, such as levees or culverts, that impede water movement. Another important element is the reintroduction of natural meanders and the restoration of riverbed morphology to create varied flow conditions, including riffles, pools, and side channels. These variations are crucial for supporting a wide range of fish species and other aquatic organisms.

The benefits of visszafolyósítási extend beyond ecological improvements. By restoring natural floodplains, the process can enhance flood control by providing areas for water to spread out, thus reducing peak flows downstream. It can also improve water quality by promoting natural filtration processes within the restored wetlands and floodplains. Furthermore, visszafolyósítási can contribute to landscape revitalization, creating more aesthetically pleasing and biodiverse environments for recreation and tourism. Several projects across Hungary have implemented visszafolyósítási principles with measurable success in restoring ecological health and hydrological functionality to their rivers.
