The Peninsular Rivers

Correct answer: A, because the Godavari is a large and important river of South India. The Godavari is a major Peninsular river and has a large drainage basin. It flows generally eastward across the Deccan region and is important for water supply, agriculture, settlements, and regional geography. Because of its size and importance, it is popularly called the “Ganga of the South.” B is wrong because the Godavari does not originate in the Himalayas; it rises in the Peninsular region. C is wrong because the river generally flows eastward and reaches the Bay of Bengal, not the Arabian Sea. D is wrong because it does not flow only through deserts; it crosses varied landscapes and supports populated agricultural areas. Memory cue: Godavari is a major southern Peninsular river, not a Himalayan river.

Peninsular rivers are rain-fed so their flow changes with seasons. Exam tip: distinguish them from perennial Himalayan rivers.

The eastward slope of the plateau takes rivers toward the Bay of Bengal. Exam tip: connect river direction with slope.

Narmada and Tapi flow westward through rift valleys. Exam tip: remember them as west-flowing rivers.

Godavari is the longest peninsular river and drains a large area. Exam tip: connect Dakshin Ganga with Godavari.

Krishna is an important water source for agricultural areas of South India. Exam tip: remember river uses too.

Kaveri plays an important role in irrigation and agriculture in South India. Exam tip: connect Kaveri with Karnataka and Tamil Nadu.

Mahanadi flows eastward and forms a delta on the Odisha coast. Exam tip: connect Mahanadi with the Bay of Bengal and Odisha.

Narmada rises from Amarkantak and flows westward into the Arabian Sea. Exam tip: remember its source and direction together.

The direct answer is A: both flow westward into the Arabian Sea. Narmada and Tapi are important west-flowing Peninsular rivers. Most large Peninsular rivers flow east because of the general slope, but these two follow westward valleys and reach the Arabian Sea. A is correct because it gives both the direction and the destination. B is wrong because east-flowing rivers such as Godavari, Krishna and Kaveri reach the Bay of Bengal, not Narmada and Tapi. C is wrong because neither is a tributary of the Ganga. D is wrong because both rise in the Peninsular highlands, not the Himalayas. Memory cue: Narmada and Tapi are the famous west-flowing pair.

Godavari rises near Nashik in Maharashtra from the Western Ghats. Exam tip: connect Godavari with Maharashtra and Western Ghats.

Krishna rises near Mahabaleshwar in the Western Ghats. Exam tip: link Krishna with Western Ghats and eastward flow.

Kaveri rises from the Brahmagiri region of the Western Ghats. Exam tip: remember its origin and South India together.

Western Ghats are near the western coast so east-flowing rivers travel farther. Exam tip: link length with source-coast distance.

The short distance between source and Arabian Sea makes their course shorter. Exam tip: remember the location of Western Ghats.

Rivers generally flow from higher land toward lower land, following the overall slope of the surface. Much of the Deccan Plateau has a general eastward slope, so many important peninsular rivers move eastward and eventually reach the Bay of Bengal. The slope does not determine every detail of every river, because local relief, rock structure, and drainage patterns can influence individual courses. However, at the broad regional level, the eastward gradient is a major reason for the common direction of flow.

Option A is correct because it describes the general effect of the Deccan Plateau’s slope. The other choices use absolute or impossible claims. The slope does not turn all rivers northward, stop rivers from reaching the sea, or make them completely underground. A question about drainage direction should be approached by identifying the higher and lower sides of the land. Since the plateau generally descends eastward, eastward flow is the expected broad pattern, while exceptions do not invalidate the general rule.

The direct answer is A: the Kaveri river system. Shivanasamudra Falls is located on the Kaveri River in Karnataka. The Kaveri flows over rocky terrain and forms the well-known waterfall, which is also associated with hydroelectric power generation. The reasoning is to match the named waterfall with its river rather than with a broad regional river basin. Option A is correct because Shivanasamudra is a famous waterfall of the Kaveri. Option B, Narmada, is a west-flowing river of central India and is associated with different waterfalls and a different drainage system. Option C, Indus, belongs mainly to the northwestern Himalayan drainage system and is not the river at Shivanasamudra. Option D, Brahmaputra, is associated with the Himalayan and northeastern drainage system and does not form this Karnataka waterfall. The place is in southern India, and that regional clue supports Kaveri. A common mistake is to choose Narmada simply because it is also a famous Peninsular river; the question asks for the particular river carrying the waterfall. Memory cue: Shivanasamudra—Kaveri, Karnataka.

Pranhita is a major tributary of the Godavari. Exam tip: study tributaries of the Godavari system separately.

Tungabhadra is a major tributary of the Krishna River. Exam tip: remember Tungabhadra in the Krishna system.

Kabini is an important tributary of the Kaveri river system. Exam tip: connect Kaveri's tributaries with South India.

Mahi and Sabarmati flow westward toward the Arabian Sea region. Exam tip: remember the list of west-flowing peninsular rivers.

Luni is an example of inland drainage in the dry region of Rajasthan. Exam tip: connect Luni with arid regions.

River valleys mature over time on old stable terrain. Exam tip: link mature valleys with old plateaus.

East-flowing rivers go toward the Bay of Bengal and west-flowing rivers toward the Arabian Sea. Exam tip: study direction and mouth together.

All three flow eastward and drain into the Bay of Bengal. Exam tip: connect them with delta formation.
