Abstract

This article explores the processes of anthropogenic eutrophication occurring in the Poti coastal zone (eastern part of the Black Sea). The paper analyzes the impact of the Rioni River runoff and urban pressure on water quality. Based on field-visual monitoring, hotspots of hyperproduction of opportunistic algae (e.g., Ulva lactuca) have been identified. The study highlights the negative impact of ecosystem degradation on the region's recreational potential and offers preventive recommendations.
