Difficulty: EasyDrainage System and Water Resources of India

Which of the following statements regarding the major west-flowing rivers of Peninsular India, Narmada and Tapti (Tapi), are correct?

  1. The Narmada river flows westward through a rift valley bounded by the Vindhya range to the north and the Satpura range to the south.Answer
  2. The Tapti river originates in the Betul district of Madhya Pradesh and drains into the Arabian Sea through the Gulf of Khambhat.Answer
  3. C
    Both the Narmada and Tapti rivers form extensive deltas near their river mouths along the western coast.
  4. D
    The Narmada river originates from the Chemayungdung glacier in the Great Himalayas.

Answer

The correct statements are that the Narmada river flows westward through a rift valley between the Vindhya and Satpura ranges, and the Tapti river originates in the Betul district of Madhya Pradesh and drains into the Arabian Sea through the Gulf of Khambhat.
The Narmada river flows westward in a rift valley bounded by the Vindhyas in the north and Satpuras in the south. The Tapti river originates from the Satpura range in Betul district, Madhya Pradesh, and flows westward into the Gulf of Khambhat (Arabian Sea). Both of these statements correctly describe the major west-flowing peninsular rivers.

Step-by-Step Solution

1
Analyze the course and landform features of the Narmada River
Narmada rises from Amarkantak Plateau and flows west through a trough/rift valley between Vindhyan and Satpura ranges.
This confirms the structural valley path of Narmada.
2
Analyze the origin and mouth of the Tapti River
Tapti rises in Multai, Betul district of Madhya Pradesh, flowing westward into the Gulf of Khambhat (Arabian Sea).
This confirms the geographic facts regarding Tapti.
3
Evaluate coastal features (estuaries vs deltas) for west-flowing rivers
West-flowing rivers carry less silt across hard rocky terrain and form estuaries rather than deltas.
This refutes the assertion that Narmada and Tapti form extensive deltas.
