Consider the following pairs:

National Park River flowing through the Park
1. Corbett National Park Ganga
2. Kaziranga National Park Manas
3. Silent Valley National Park Kaveri

Which of the above pairs is/are correctly matched?

  1. A1 and 2
  2. B3 only
  3. C1 and 3
  4. DNone
Show answer

Answer: (D) None

None of the pairs is correctly matched:

Pair 1 — Corbett National Park is associated with the Ramganga river (a tributary of the Ganga), NOT the Ganga itself. The Ganga does not flow through Corbett.

Pair 2 — Kaziranga National Park lies in the floodplains of the Brahmaputra river, NOT the Manas river. The Manas river flows through Manas National Park (a separate national park in Assam).

Pair 3 — Silent Valley National Park in Kerala has the Kunthi river (Kunthipuzha) flowing through it, NOT the Kaveri. The Kaveri originates in Kodagu (Coorg) in Karnataka and flows through Tamil Nadu — nowhere near Silent Valley in the Palakkad district of Kerala.

So the answer is (d) — None of the pairs is correctly matched. This is a classic geography factual question testing map-based knowledge.

Why this was asked

National parks and their rivers is a standard factual geography topic that requires precise map-based knowledge of India's protected areas and drainage systems.

UPSC uses deliberately confusing pairs where famous rivers are matched with famous parks, but not the correct ones - Corbett is linked with Ramganga not Ganga, Kaziranga with Brahmaputra not Manas, and Silent Valley with Kunthi river not Kaveri.

The question tests whether students can distinguish between geographically close but distinct features - like Manas river versus Manas National Park, or tributary relationships like Ramganga being part of Ganga system but not the main river.

Corbett National Park & Ramganga River

Geography Corbett National Park Ganga

Corbett National Park: Location, Rivers & Key Facts

Must know

Corbett National Park is in Uttarakhand, established in 1936 as India's first national park

Exam traps

Trap: UPSC tests confusion between Ganga and Ramganga — Corbett has Ramganga, not Ganga

Common Error: Mixing up Corbett (Ramganga) with parks actually on the Ganga like Rajaji National Park

Memory Aid: Ram-ganga flows through Corbett — both have strong consonant sounds (R-C connection)

Kaziranga National Park & Brahmaputra

Geography Kaziranga National Park Manas

Kaziranga vs Manas: Two Different Parks in Assam

Must know

Kaziranga National Park lies in Brahmaputra floodplains, NOT Manas river

River Geography

Kaziranga spreads across the Brahmaputra's floodplains in central Assam. The Manas River is a separate tributary that flows through Manas National Park in western Assam, near the Bhutan border.

Exam traps

Major Trap: UPSC swaps Kaziranga-Brahmaputra with Manas-Manas — these are two different parks

Memory Aid: Kazi-ranga sounds like Brahma-putra (both have 4 syllables)

Location Confusion: Both parks are in Assam but Kaziranga is central, Manas is western near Bhutan

Silent Valley & Kunthi River

Geography Silent Valley National Park Kaveri

Silent Valley National Park: Kerala's Western Ghats Gem

Must know

Silent Valley is in Kerala's Palakkad district, NOT connected to Kaveri river

Kunthi River (Kunthipuzha) flows through Silent Valley

Kaveri River originates in Karnataka and flows through Tamil Nadu — nowhere near Kerala

Good to know

Part of Nilgiri Biosphere Reserve in Western Ghats

Geography & Rivers

Silent Valley National Park lies in Kerala's Western Ghats. The Kunthi River (also called Kunthipuzha) flows through the park, eventually joining the Bharathapuzha system that drains into the Arabian Sea.

Silent Valley Significance

Tropical evergreen forest — one of the last undisturbed patches in Western Ghats

No cicadas — hence the name 'Silent' Valley (local belief, though scientifically debated)

Biodiversity hotspot — endemic species of plants and animals

Hydroelectric controversy — proposed dam was cancelled due to environmental concerns in 1980s

Exam traps

Geographic Trap: Kaveri is a Karnataka-Tamil Nadu river — completely different from Kerala's rivers

State Confusion: Silent Valley is Kerala, Kaveri is Karnataka origin — different South Indian states

Drainage Direction: Silent Valley drains to Arabian Sea, Kaveri drains to Bay of Bengal

Common Mixing: Don't confuse Kaziranga-Brahmaputra with Manas-Manas (both in Assam)

Tributary Trap: Corbett has Ramganga (Ganga tributary), not Ganga directly

State Geography: Silent Valley is Kerala, Kaveri is Karnataka-Tamil Nadu system

Delta Confusion: Sundarbans is Ganga delta, Bhitarkanika is Mahanadi delta
