India faces a significant water resource disparity, with some regions are experiencing from uncertain floods while others suffering from severe droughts. The Interlinking of Rivers (ILR) project is one of the possible initiatives aimed at addressing the imbalance by transferring water from surplus river basins to deficit through a network of canals and reservoirs. The India’s ambitious Rs 9,393 crore Ken-Betwa River interlinking project will impact very significantly on socio-economic life of two million people of Bundelkhand region, India. In Bundelkhand region, there is a severe problem of lack of irrigation in one region and water logging in others. This project has the potential to assess the hydrological and socio-economic impacts by the application of the Water Evaluation and Planning (WEAP) software, which is a decision-support tool, is employed to model water availability, demand and allocation across various sectors, including agriculture, domestic and ecological needs. The study integrates the hydrological, climatic and demand-based data of surplus and deficit river. The results highlight the potential benefits of optimized water distribution and reduced seasonal water shortages. The findings underscore the importance of Integrated Water Resource Management (IWRM) and adaptive planning to ensure the long-term success of the project.
