Rejuvenation of Kalyani River, Uttar Pradesh (India): A Study using Geospatial Modeling

Rivers play a crucial role in maintaining ecological balance and providing essential resources; however, many are facing significant degradation, particularly in India, where urbanization and population growth exacerbate water scarcity. This study focuses on the Kalyani River, located in Barabanki district, Uttar Pradesh (India), which spans approximately 69.65 km and is vital for local communities. We employed an integrated approach combining geospatial technology, the HEC-RAS (Hydrologic Engineering Centers-River Analysis System) model, and field verification to assess river conditions and identify restoration needs. Our analysis revealed critical challenges affecting the Kalyani River, including siltation and blockages that hinder flow and contribute to flooding. The results indicate a recommended excavation length of approximately 22.37 km in the Nindora block, along with a total cleaning length of around 47.28 km for both Nindora and Fatehpur blocks. These findings underscore the necessity for immediate eco-restoration efforts to rejuvenate the river ecosystem and mitigate the impacts of human-induced changes. Furthermore, we mapped critical zones requiring intervention, emphasizing the need for community engagement in conservation initiatives. This study highlights the importance of not only addressing the physical restoration of the river but also fostering long-term ecological health through sustainable management practices. By comparing our findings with established river restoration projects, we contextualize the significance of our approach to enhance the resilience of the Kalyani River. Ultimately, this research offers valuable insights and actionable recommendations that can aid local authorities and stakeholders in implementing effective river management strategies, contributing to improved water security and ecological sustainability in the region.
