Utilizing a combination of field measurements, hydrodynamic modeling, and ecological assessments, the research examines changes in flow velocity, sediment transport, and water quality resulting from channel modifications. The study also explores the subsequent effects on ecosystem services, including habitat provision, water purification, and flood regulation. The findings reveal that while certain modifications may enhance specific hydraulic functions, they often lead to unintended ecological consequences, such as habitat degradation, loss of biodiversity, and reduced water quality. Furthermore, the study highlights the trade-offs between improving hydraulic efficiency and maintaining ecological integrity. It demonstrates that sustainable channel management requires a balanced approach that considers both engineering objectives and environmental impacts. The research emphasizes the importance of incorporating ecosystem-based approaches in the design and implementation of channel modifications to preserve or enhance ecosystem services.
