The Narmada River, also known as the Reva, is India's fifth longest river and the country's longest west-flowing river, as well as the state's largest flowing river. Narmada flows through the Indian states of Madhya Pradesh and Gujarat. Along with the Tapti River, it is one of only two large rivers in peninsular India that flow from east to west (longest west flowing river). It is one of India's rivers that flows through a rift valley between the Satpura and Vindhya mountain ranges. The Narmada does not produce a delta since it is a rift valley river; rift valley rivers form estuaries. It is also known as the "Life Line of Madhya Pradesh and Gujarat" because of its numerous contributions to the states of Madhya Pradesh and Gujarat. This article will explain to you about the Narmada which will be helpful in Geography preparation for the UPSC Civil service exam.
