Zorluk: OrtaDrainage System and Water Resources of India

Which of the following statements regarding the characteristics of Peninsular and inland river systems in India are correct?

  1. The Narmada and Tapti rivers flow through rift valleys created due to tectonic faulting along the Vindhya and Satpura ranges.Cevap
  2. The Cauvery River receives rainfall from both the South-West and North-East monsoons, maintaining relatively low discharge fluctuation throughout the year.Cevap
  3. C
    The Godavari River originates from the Amarkantak Plateau in Madhya Pradesh and forms the largest river basin in Southern India.
  4. The Luni River is a major inland drainage system of Rajasthan that discharges into the Rann of Kutch without reaching the sea.Cevap

Cevap

The statements confirming that Narmada and Tapti flow through tectonic rift valleys, Cauvery receives water from both monsoons, and Luni terminates in the Rann of Kutch are correct.
The statements highlighting Narmada and Tapti's rift valley course, Cauvery's dual-monsoon regime, and Luni's endorheic flow into the Rann of Kutch are accurate. Narmada and Tapti flow westwards through structural troughs formed by faulting. Cauvery is unique among Peninsular rivers because its upper basin gets rainfall from the South-West monsoon and its lower basin from the North-East monsoon. Luni is the primary river of the Rajasthan inland drainage basin.

Adım Adım Çözüm

1
Analyze structural geology of West-flowing Peninsular rivers
Narmada and Tapti flow through rift valleys between the Vindhya, Satpura, and Ajanta ranges, forming estuaries instead of deltas.
Verify geological origin and flow paths of major West-flowing Peninsular rivers.
2
Evaluate rainfall regimes of the Cauvery basin
The upper catchment in Karnataka gets rain during June–September (South-West monsoon) and the lower catchment in Tamil Nadu gets rain during October–December (North-East monsoon), making Cauvery comparatively perennial.
Determine seasonal variation patterns in Peninsular river flows.
3
Verify origin points of major Peninsular rivers
The Godavari River originates at Trimbakeshwar (Western Ghats, Maharashtra). Amarkantak Plateau is the source of the Narmada and Son rivers.
Identify common geographic origin misconceptions.
4
Examine inland drainage characteristics in Western India
Luni is the principal river of the arid west, originating near Ajmer and terminating in the salt marshes of the Rann of Kutch.
Classify inland/ephemeral river features of India.
