INDIAN RIVER SYSTEM - PART 1
• Himalayan Rivers are formed by melting snow & glaciers and flow throughout year.
• Deccan Rivers are rain-fed and therefore fluctuate in volume. Many of these are non- perennial. Coastal streams, especially on the west coast are short in length and most of them are non-perennial.
• The streams of inland drainage basin of western Rajasthan are few and far apart. Most of them are of an ephemeral character.
• About 77% of drainage is towards Bay of Bengal and rest is towards Arabian Sea.
• Bhagirathi and Alaknanda join at Dev Prayag to form the River Ganga. Ganga traverses through Uttarakhand, Uttar Pradesh, Bihar and West Bengal.
• Indus rises near Mansarovar in Tibet and finally falls in the Arabian Sea near Karachi.
• Indus is known as Shiquan in Tibet
• Son is the largest tributary of Ganga from south. Gandhi Setu on Son River near Patna is highest bridge in Asia.
• Brahmaputra is known as Tsangpo in Tibet, Dihang in Arunachal & Jamuna in Bangladesh.
• Near Passighat the Debang and Lohit join the river Brahmaputra crosses into Bangladesh downstream of Dhubri.
• It becomes Padma after meeting Ganga & finally discharges as Meghna in Bay of Bengal.
• Principal tributaries of Brahmaputra are Subansiri, Jia Bhareli, Dhansiri, Puthimari, Pagladiya and the Manas.
• Barak River, the Head Stream of Meghna, rises in the hills in Manipur. It continues in Bangladesh till the combined Ganga - Brahmputra join it near Bhairab Bazar.
• Lohit makes delta in reverse when it joins Brahmaputra from south. Majuli (Assam) in Brahamputra is the largest Riverine Island in the world. It has been declared world heritage site by UNESCO.
• Chambal is known for its Badland topography
• Dhaunadar Falls or Marble Falls lie on River Narmada near Jabalpur
• Godavari has the second largest river basin covering 10 per cent of the area of India.
• A few rivers in Rajasthan do not drain into the sea. Few of them drain into the Salt lakes while others like Luni, Machhu, Rupen, Saraswati, Banas and Ghaggar are lost in the desert.
• Narmada forms traditional boundary between North and South India, and drains M.P., Gujarat and Maharashtra. Existing irrigation projects in the Narmada are Matiyari, Rani Avantibai Sagar, Barna, Tawa and Sukta- all in Madhya Pradesh, and Karjan project in Gujarat. Important Projects under implementation are Kolar, Man, Omkareshwar, Maheshwar and Sardar Sarovar.
• Tapi drains M.P, Maharashtra and Gujarat. Kakrapara, Utsai are major projects, alongwith Hatnur Dam in Maharashtra and Ukai Dam in Gujarat. Tapi is known as the twin or hand• made of Narmada
• The Godavari River has a drainage area in six states-Maharashtra, Andhra Pradesh, Karnataka, Madhya Pradesh, Chattisgarh and Orissa. It has "Sriramsagar project" in Nizamabad District. Aruthur Cotton, Trimbakeshwar are Waterfalls on it. Godavari is called as Ganga of South or Bridh Ganga.
