River Linking Seminar Abstract Report


River linking, also known as interlinking of rivers, is a large-scale water management project that aims to connect rivers and water bodies through an extensive network of canals and reservoirs. The primary objectives of river linking projects are to address water scarcity in certain regions, alleviate floods in others, and facilitate the efficient transfer of water from surplus river basins to water-deficient areas. Proponents argue that it can improve irrigation, generate hydroelectric power, and enhance overall water resource management. However, river linking projects also face significant environmental, ecological, and social challenges, raising concerns about their long-term sustainability and impact on ecosystems and communities.

River Linking, also known as Interlinking of Rivers (ILR), is a large-scale water management project that aims to transfer water from water-surplus river basins to water-deficit river basins in order to address water scarcity and uneven distribution of water resources in India. The idea behind river linking is to create a network of canals and reservoirs to facilitate the transfer of water between rivers, with the ultimate goal of enhancing irrigation, improving water availability, mitigating floods, and generating hydroelectric power.

Here’s a detailed overview of the River Linking technique:


India is a country with diverse climatic conditions, and its rivers exhibit variations in water availability throughout the year. Some regions experience floods during the monsoon season, while others face acute water scarcity during dry periods. To address this problem, the Indian government proposed the idea of river linking as a potential solution to balance the distribution of water resources.

Components of River Linking

The River Linking project involves two main components: the Himalayan Rivers Interlink and the Peninsular Rivers Interlink.

a. Himalayan Rivers Interlink:
This component focuses on the rivers originating from the Himalayan region in the northern part of India. It aims to transfer excess water from these rivers to water-deficient areas in northern, western, and central India. Some of the major rivers involved in this component are the Ganges, Brahmaputra, and Yamuna.
b. Peninsular Rivers Interlink:
The Peninsular component deals with the rivers in the central and southern regions of India. It aims to divert surplus water from the water-abundant rivers in the eastern part of the country to the water-scarce rivers in the western and southern parts. Major rivers in this component include the Godavari, Krishna, Mahanadi, and Cauvery.

Key Objectives

  • Water Security: To provide water security to water-deficient regions by transferring surplus water from water-abundant regions.
  • Irrigation: To enhance irrigation facilities and agricultural productivity in arid and semi-arid regions.
  • Flood Control: To mitigate the impact of floods in certain regions by diverting excess water to areas in need.
  • Hydropower Generation: To generate hydroelectric power through the construction of reservoirs and dams.

Challenges and Concerns:

The River Linking project has been met with various challenges and concerns, both environmental and social:

  • Environmental Impact: Building large canals, dams, and reservoirs can result in significant ecological disturbances, habitat loss, and changes in river flow patterns, affecting biodiversity and local ecosystems.
  • Displacement: The project may lead to the displacement of local communities living in the areas where canals and reservoirs are constructed.
  • Cost and Feasibility: The project is massive in scale and involves substantial financial investments. Its feasibility and cost-effectiveness have been subjects of debate.
  • Interstate Water Disputes: River water-sharing has historically been a contentious issue between states, and the river linking project may exacerbate existing water disputes.
  • Climate Change: Changing climate patterns can affect river flows and may impact the success of the project.

River Linking project in India was still in the planning and development stages. Some individual river-linking projects have been initiated on a smaller scale, but the comprehensive interlinking of all rivers remained a complex and ongoing process.
