Q36 (IAS/2015) Geography › Indian Physical Geography › Peninsular river systems Official Key

Consider the following rivers : 1. Vamsadhara 2. Indravati 3. Pranahita 4. Pennar Which of the above are tributaries of Godavari?

Result
Your answer:  ·  Correct: D
Explanation

Vamsadhara and Pennar are not tributaries of Godavari[2]. Vamsadhara is an important east flowing river between Mahanadi and Godavari, in Southern Odisha and North Eastern Andhra Pradesh[1], making it an independent river system. Similarly, Pennar is a separate east-flowing peninsular river.

In contrast, Godavari receives a large number of tributaries, particularly on its left bank, such as Purna, Maner, Penganga, Pranhita (the combined Wardha and Wainganga), Indravati, Tal, and Sabri[3]. This clearly establishes that both Indravati and Pranahita (Pranhita) are tributaries of the Godavari.

Therefore, among the given rivers, only Indravati (2) and Pranahita (3) are tributaries of Godavari, making option D the correct answer. This is a straightforward question testing knowledge of the Godavari river system, which is the largest peninsular river of India.

This is a textbook 'Sitter' directly from NCERT Class XI (India: Physical Environment). The question tests the fundamental distinction between a 'tributary' (Indravati, Pranahita) and an 'independent river basin' (Pennar, Vamsadhara). If you rely solely on text without visualizing the North-South coastal sequence on a map, you will falter.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
Is the Vamsadhara River a tributary of the Godavari River?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"**Vamsadhara and Pennar** are not the tributaries of Godavari.River Vamsadhara is an important east flowing river between Mahanadi and Godavari, in Southern Odisha and North Eastern Andhra Pradesh."
Why this source?
  • Explicitly states that Vamsadhara is not a tributary of the Godavari.
  • Describes Vamsadhara as an independent east-flowing river located between the Mahanadi and Godavari basins, implying it does not join the Godavari.

Strength: 5/5
“Godavari is the largest river length 1465 km and basin area of 302063.93 sq km of peninsular India. It rises in the Western Ghats from a spring below Nasik, drains eastern and southeastern Maharashtra, Bastar plateau (Chhattisgarh), and Telengana and Andhra regions of Andhra Pradesh. It receives a large number of tributaries, particularly on its left bank, such as Purna, Maner, Penganga, Pranhita (the combined Wardha and Wainganga), Indravati, Tal, and Sabri. The Manjira is the only important right bank tributary. The Indravati and Sabri are the two streams which rise on the western slopes of the Eastern Ghats, but they flow east and south-eastwards, respectively.”
Why relevant

Gives a detailed list of major Godavari tributaries (Indravati, Sabari, Penganga, Pranhita, Purna, Wainganga, Manjra, etc.).

How to extend

A student can check whether Vamsadhara appears among these named tributaries; if not, that is a clue it may not be a Godavari tributary and warrants checking its independent course on a map.

Why relevant

Table lists Godavari’s main tributaries explicitly, providing a concise roster to compare against.

How to extend

Compare this roster with a list/map of rivers in the relevant region to see if Vamsadhara is included or omitted.

Strength: 4/5
“The Godavari is the largest Peninsular river. It rises from the slopes of the Western Ghats in the Nasik district of Maharashtra. Its length is about 1500 km. It drains into the Bay of Bengal. Its drainage basin is also the largest among the peninsular rivers. The basin covers parts of Maharashtra (about 50 per cent of the basin area lies in Maharashtra), Madhya Pradesh, Odisha and Andhra Pradesh. The Godavari is joined by a number of tributaries, such as the Purna, the Wardha, the Pranhita, the Manjra, the Wainganga and the Penganga. The last three tributaries are very large.”
Why relevant

Describes Godavari basin extent (Maharashtra, Madhya Pradesh, Odisha, Andhra Pradesh) and names several tributaries, giving geographic scope for where tributaries belong.

How to extend

Locate Vamsadhara on a political or drainage map of Odisha/Andhra to see if its basin lies inside the Godavari basin or drains separately to the Bay of Bengal.

Strength: 3/5
“The rivers which follow the general direction of slope are known as the consequent rivers. Most of the rivers of peninsular India are consequent rivers. For example, rivers like Godavari, Krishna, and Kaveri, descending from the Western Ghats and flowing into the Bay of Bengal, are some of the consequent rivers of Peninsular India (Fig. 3.1).”
Why relevant

States the general pattern that many peninsular rivers (including Godavari, Krishna, Kaveri) descend from the Western Ghats and flow east into the Bay of Bengal.

How to extend

Use this pattern plus the Vamsadhara’s source and flow direction (from a map) to judge whether it follows an independent eastward course to the sea or joins a larger system like the Godavari.

Strength: 3/5
“Pranhita, and the Manjra are its principal tributaries. The Godavari is subjected to heavy floods in its lower reaches to the south of Polavaram, where it forms a picturesque gorge. It is navigable only in the deltaic stretch. The river after Rajamundri splits into several branches forming a large delta. The Krishna is the second largest eastflowing Peninsular river which rises near Mahabaleshwar in Sahyadri. Its total length is 1,401 km. The Koyna, the Tungbhadra and the Bhima are its major tributaries. Of the total catchment area of the Krishna, 27 per cent lies in Maharashtra, 44 per cent in Karnataka and 29 per cent in Andhra Pradesh and Telangana.”
Why relevant

Notes major tributaries (Pranhita, Manjra) and describes Godavari’s lower reaches and delta behaviour, pointing to where tributaries typically join.

How to extend

A student could check whether Vamsadhara’s confluence (if any) is located in these lower-reach/delta areas or whether it reaches the coast separately.
