The Peninsular Rivers

Overview

Peninsular India is home to many significant rivers. These rivers play a crucial role in the ecosystem and irrigation. The main water divide in this region is formed by the Western Ghats. This mountain range runs from north to south along the western coast.

Major Rivers

  1. Mahanadi
  2. Godavari
  3. Krishna
  4. Kaveri

These rivers mostly flow eastwards and empty into the Bay of Bengal. They form deltas at their mouths, which are fertile and support agriculture.

There are also many short rivers and streams flowing westward. The Narmada and Tapi are two significant rivers that flow west and create estuaries.

Key Characteristics

  • The drainage basins of the peninsular rivers are generally smaller in size compared to other major rivers in India.

The Narmada Basin

  • Source: The Narmada River rises in the Amarkantak hills in Madhya Pradesh.
  • Direction: It flows westward through a rift valley formed by faulting.
  • Notable Features:
    • Marble Rocks near Jabalpur: The river flows through a deep gorge.
    • Dhuadhar Falls: The river cascades over steep rocks.

Conservation Efforts

The Namami Devi Narmade initiative aims to conserve the Narmada River. For more information, visit Namami Devi Narmade.

Basin Coverage

  • The Narmada Basin includes parts of Madhya Pradesh and Gujarat.
  • All tributaries are relatively short and join at right angles.

The Tapi Basin

  • Source: The Tapi River rises in the Satpura ranges in Betul, Madhya Pradesh.
  • Length: It is shorter than the Narmada and also flows in a rift valley.
  • Basin Coverage: It covers parts of Madhya Pradesh, Gujarat, and Maharashtra.

Coastal Rivers

  • The coastal plains between the Western Ghats and the Arabian Sea are narrow, leading to shorter rivers.
  • Notable west-flowing rivers include:
    • Sabarmati
    • Mahi
    • Bharathpuzha
    • Periyar

The Godavari Basin

  • Source: The Godavari rises in the Western Ghats near Nasik, Maharashtra.
  • Length: Approximately 1,500 km, making it the largest peninsular river.
  • Drainage Basin: It covers parts of Maharashtra, Madhya Pradesh, Odisha, and Andhra Pradesh.

Tributaries

The Godavari has several tributaries:

  • Purna
  • Wardha
  • Pranhita
  • Manjra
  • Wainganga
  • Penganga

Because of its size, the Godavari is often called the Dakshin Ganga.

The Mahanadi Basin

  • Source: The Mahanadi rises in the highlands of Chhattisgarh.
  • Length: About 860 km.
  • Basin Coverage: Shared by Maharashtra, Chhattisgarh, Jharkhand, and Odisha.

The Krishna Basin

  • Source: Rises from a spring near Mahabaleshwar.
  • Length: About 1,400 km.
  • Drainage Site: Reaches the Bay of Bengal.

Tributaries

Significant tributaries include:

  • Tungabhadra
  • Koyana
  • Ghatprabha
  • Musi
  • Bhima

Basin Coverage

The Krishna Basin spans parts of Maharashtra, Karnataka, and Andhra Pradesh.

The Kaveri Basin

  • Source: The Kaveri rises in the Brahmagri range of the Western Ghats.
  • Length: About 760 km.
  • Drainage Site: Reaches the Bay of Bengal near Cuddalore, Tamil Nadu.

Notable Features

  • Waterfall: The Kaveri creates the second largest waterfall in India called Shivasamudram Falls.
  • Hydroelectric Power: Powers cities like Mysuru, Bengaluru, and the Kolar Gold Field.

Smaller Rivers

There are also rivers flowing eastward such as:

  • Damoder
  • Brahmani
  • Baitarni
  • Subarnrekha

Fun Facts

  • Water Coverage: 71% of Earth's surface is water, but 97% of that is saltwater.
  • Freshwater Availability: Only 3% of water is freshwater. Three-quarters of that is trapped in ice!
