#1
The Godavari is India's longest Peninsular river (1,465 km), originating at Trimbakeshwar and draining into the Bay of Bengal.
#2
The Krishna River originates near Mahabaleshwar, draining four states, with the Tungabhadra and Bhima serving as its largest tributaries.
#3
The Cauvery originates at Talakaveri in the Brahmagiri Hills and remains perennial due to rainfall from both the Southwest and Northeast monsoons.
#4
East-flowing peninsular rivers construct expansive deltas, whereas west-flowing rift-valley rivers (Narmada and Tapi) form estuaries.
#5
The Narmada originates at the Amarkantak Plateau and flows westward between the Vindhya and Satpura ranges, creating the Dhuandhar Falls.
#6
The Godavari basin encompasses 312,812 square kilometres across Maharashtra, Telangana, Andhra Pradesh, Chhattisgarh, and Odisha, forming the Polavaram irrigation project.
#7
Major left-bank tributaries of the Godavari include the Penganga, Wainganga, Wardha (which unite as the Pranhita), and Indravati, while the Manjra is its chief right-bank tributary.
#8
The Krishna River flows 1,400 kilometres across Maharashtra, Karnataka, Telangana, and Andhra Pradesh, emptying into the Bay of Bengal at Hamsaladeevi.
#9
Major tributaries of the Krishna include the Ghataprabha, Malaprabha, Koyna, Dudhganga, and Musi, on whose banks the city of Hyderabad is situated.
#10
The Cauvery River forms two major riverine islands in Karnataka, Srirangapatna and Shivanasamudra, the latter hosting India's first major hydroelectric station established in 1902.
#11
Principal tributaries of the Cauvery include the Harangi, Hemavati, Shimsha, and Arkavathy on the north bank, and the Lakshmana Tirtha, Kabini, Bhavani, and Amaravati on the south bank.
#12
The Tapi (Tapti) River originates at Multai in the Betul district of Madhya Pradesh, flowing 724 kilometres through a rift valley between the Satpura and Ajanta ranges.
#13
The Sabarmati River originates in the Aravalli Range in Udaipur district, Rajasthan, flowing 371 kilometres to discharge into the Gulf of Khambhat.
#14
The Luni River originates in the Pushkar Valley of the Aravallis, flows 495 kilometres through southwest Rajasthan, and terminates into the marshy Rann of Kutch without reaching the sea.
#15
The Sharavati River in the Western Ghats of Karnataka drops 253 metres at Jog Falls (Gersoppa), generating power at the Mahatma Gandhi Hydroelectric Project.
Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
Peninsular rivers in India are ancient, rain-fed drainage systems flowing through mature, graded valleys. Most major peninsular rivers, such as the Godavari, Krishna, and Cauvery, originate in the Western Ghats and flow east into the Bay of Bengal, forming fertile deltas along the eastern seaboard. In contrast, the Narmada and Tapi flow west through narrow tectonic rift valleys between the Vindhya and Satpura ranges, emptying into the Arabian Sea through estuaries without building extensive delta plains.
For UPSC and State PSC exams, tributary mapping and flow anomalies are recurring question targets. Remember that the Godavari is India's longest peninsular river, often called Dakshin Ganga, with the Pranhita being its largest tributary. Do not fall into the exam trap regarding river seasonality: unlike other peninsular rivers, the Cauvery remains perennial because it receives rainfall from both the Southwest and Northeast monsoons. In your map test preparation, verify that the Narmada flows between the Vindhyas and Satpuras.
