Modelling Estuarine Habitats in the Upper Sea Scheldt: Human-Induced Adaptations

Explore a research study on modelling estuarine habitats in the Upper Sea Scheldt under various human-induced channel and floodplain adaptations. The study examines the impact of interventions on habitat size, water quality, ecosystem, and more, providing insights into the future of the estuarine environment. Detailed analysis includes climate scenarios, intervention levels, and results on tidal amplitudes, surface area habitats, and effects of different alternatives and scenarios.
