Abstract:
The article addresses the problem of reducing eutrophication in surface water bodies under increasing nutrient loading and anthropogenic pressure. A gabion-based bioplateau is considered as a local bio-engineering structure that combines bank protection with natural water filtration. The system includes gabion blocks with crushed-stone filling, a filtration-sorption soil layer and emergent aquatic vegetation. These components provide mechanical filtration, sorption and biochemical transformation of nitrogen and phosphorus compounds. The study shows that such structures can improve water quality, stabilize coastal ecosystems, reduce the risk of eutrophication and operate with relatively low maintenance costs. Gabion-based bioplateaus are recommended for use in reservoirs and recreational water bodies in Ukraine.
