Multipurpose river valley projects are basically designed for the development of irrigation for agriculture and electricity through the construction of dams. Initially, dams were built only for storing rain water to prevent flooding but now it became multipurpose. Here, we are giving the list of important river-valley projects in India which will help the students for quick revision.
