Gabion weirs are essential structures used in river management and erosion control. They have been increasingly utilized due to their cost-effectiveness, ease of installation, and adaptability to a wide range of environments. This systematic review aims to explore the role and impact of gabion weirs in river management by examining their design, construction, and ecological implications. A comprehensive analysis of peer-reviewed literature, case studies, and reports was conducted to assess the effectiveness of gabion weirs in addressing various hydrological and geomorphological challenges. The review demonstrates that gabion weirs can play a significant role in reducing erosion, stabilizing riverbanks, improving water quality, and facilitating sediment transport. Additionally, they offer a sustainable solution for flood control, stream restoration, and habitat improvement. However, the review also highlights the importance of proper design, site selection, and maintenance practices to optimize their performance and minimize potential negative effects on ecosystems and watercourses. In conclusion, this systematic review underscores the potential of gabion weirs as a versatile and environmentally friendly tool for river management. It provides valuable insights for researchers, engineers, and policymakers seeking to enhance the understanding and implementation of gabion weirs in various hydrological settings. Further research is recommended to explore the long-term impacts of gabion weirs on ecosystems and to develop innovative designs that maximize their benefits while minimizing potential drawbacks.
