The Peninsular Rivers

Narmada flows westward into the Arabian Sea. Exam tip: remember Narmada as a west flowing exception.

Most major Peninsular rivers flow east but Narmada and Tapi flow west. Exam tip: treat them as exceptions.

The Narmada originates at Narmada Kund near the Amarkantak Plateau in Madhya Pradesh. Therefore, Amarkantak is the correct answer. Mahabaleshwar is associated with the source of the Krishna, while Gangotri and Yamunotri are associated with the Ganga and Yamuna respectively. Exam tip: Remember Amarkantak as the source region of the Narmada and Son rivers.

Godavari flows eastward into the Bay of Bengal. Exam tip: remember it as an east flowing river.

Godavari rises near Nashik in Maharashtra. Exam tip: remember Maharashtra as Godavari's source region.

Mahanadi flows eastward into the Bay of Bengal. Exam tip: treat Mahanadi as an east flowing river.

Krishna is an east flowing river and drains into the Bay of Bengal. Exam tip: remember Krishna with Godavari and Kaveri.

Kaveri flows eastward into the Bay of Bengal. Exam tip: remember Kaveri as an east flowing river of South India.

Kaveri rises from the Brahmagiri region. Exam tip: connect Kaveri with Western Ghats and South India.

East flowing rivers can form deltas by depositing sediments near the mouth. Exam tip: connect delta with deposition.

West flowing rivers often form estuaries. Exam tip: remember western coast and estuary together.

In old plateau land valleys are generally broad and shallow. Exam tip: connect old land with mature valleys.

Peninsular rivers depend more on monsoon rainfall. Exam tip: remember the difference in water sources.

Due to eastward slope of Deccan many rivers flow towards the Bay of Bengal. Exam tip: study slope and direction together.

A waterfall forms where a river drops sharply over a step, resistant rock, or change in land height. Shivanasamudra is a major waterfall on the Kaveri River in Karnataka. The river divides around the island area and creates notable falls, making the site an important geographical feature of the Kaveri’s course.

Option C is correct because Shivanasamudra is associated with the Kaveri. Ganga, Indus, and Kosi are different river systems and are not the river on which this waterfall is located. A useful memory link is “Kaveri–Shivanasamudra,” while avoiding confusion with waterfalls belonging to other Peninsular rivers.

Height differences in plateau areas can form waterfalls. Exam tip: connect waterfalls with the Peninsular Plateau.

The direct answer is B: due to low rainfall. Many Peninsular rivers depend strongly on the seasonal monsoon because their basins generally do not receive a continuous supply from large glaciers. The reasoning is: summer before or during the dry period may bring little effective rainfall → less rainwater enters streams and reservoirs → groundwater and stored water may also decline → river discharge becomes lower. Option B is correct because reduced rainfall is the direct seasonal reason for lower flow in many Peninsular rivers. Option A, high sea tides, can affect the lower mouth of a river but does not reduce the whole river’s freshwater supply. Option C, the nearby Himalayas, is geographically incorrect for Peninsular rivers and does not explain their summer discharge. Option D, delta growth, may alter the mouth or channels but is not the main cause of seasonal reduction in water. Some Peninsular rivers are dam-controlled or may receive local rain, so the statement says “many,” not every river. Exam cue: Peninsular rivers are commonly more seasonal; monsoon rainfall controls their flow.

A delta forms at the mouth of a river when the river slows down and deposits the sand, silt, and other sediments it carries. Continued deposition builds a triangular or fan-shaped landform. Wave erosion removes material rather than depositing it, so option B is incorrect. Exam tip: deltas are more likely where deposition is high and tidal or wave action is relatively weak.

The direct answer is B, east flowing. A river is called east flowing when its general course is towards the east and it finally reaches the Bay of Bengal or another eastern coastal outlet. The Godavari rises in the Western Ghats and travels across the Deccan Plateau towards the Bay of Bengal. The Krishna also rises in the Western Ghats and flows generally eastward before entering the Bay of Bengal. Therefore both rivers belong to the east-flowing group. Option A, west flowing, is wrong because west-flowing peninsular rivers such as the Narmada and Tapi enter the Arabian Sea. Option B is correct because Godavari and Krishna reach the Bay of Bengal. Option C, glacier fed, is wrong because these are mainly rain-fed peninsular rivers, not Himalayan glacier-fed rivers. Option D, inland, is wrong because inland rivers end in lakes or disappear within land rather than reaching the sea. Memory cue: Godavari and Krishna go east to the Bay of Bengal; Narmada and Tapi go west to the Arabian Sea.

Narmada and Tapi are major west-flowing Peninsular rivers. They flow westwards and drain into the Arabian Sea. Most east-flowing Peninsular rivers drain into the Bay of Bengal, so option A is incorrect. Exam tip: remember Narmada and Tapi together as west-flowing rivers.

Old stable land keeps river courses relatively fixed. Exam tip: connect fixed course with old plateau.

Mahi flows westward towards the Arabian Sea region. Exam tip: remember Mahi as a river of western India.

Sabarmati is a river of western India and flows towards the Arabian Sea region. Exam tip: connect Sabarmati with Gujarat.

The direct answer is C: Kerala. Periyar is an important river of Kerala in southwestern India. It rises in the Western Ghats and flows generally westward, eventually reaching the Arabian Sea system. It is strongly associated with Kerala because much of its course, important reservoirs and major projects lie in that state. Step by step: locate Periyar in the southern part of India; connect it with the Western Ghats; identify Kerala as its main state; then remember its westward drainage. Option C is correct. Option A, Punjab, is associated with the Indus river system and its tributaries, not Periyar. Option B, Bihar, is associated with rivers such as the Ganga, Gandak, Kosi and Son, not this southwestern river. Option D, Assam, is mainly linked with the Brahmaputra and Barak systems, not Periyar. The word “mainly” matters because rivers and their catchments may extend across administrative boundaries, but the standard school association is Periyar–Kerala. Memory cue: Periyar is a Kerala river; Kerala’s short, swift west-flowing rivers descend from the Western Ghats toward the Arabian Sea.

Bharathapuzha, also known as the Nila, is an important river of Kerala in southwestern India. It rises in the Western Ghats and flows westward toward the Arabian Sea. The river supports the landscapes and human activities of central Kerala, although its flow varies strongly with the monsoon. It is often remembered in geography as one of the notable west-flowing rivers of the Peninsular region, rather than as a river of the northern plains.

Option D is correct because Bharathapuzha is associated with Kerala. Rajasthan is mainly linked with rivers of the arid northwest, Bihar with the Ganga river system and its northern tributaries, and Ladakh with high-altitude Himalayan drainage. None of those locations identifies Bharathapuzha. The most useful memory link is “Bharathapuzha—Kerala—west-flowing Peninsular river.” This also helps distinguish it from major east-flowing rivers such as the Godavari, Krishna and Mahanadi.
