Identifying Non-Tributaries of Yamuna River

Let's analyze the given options to determine which river is not a tributary of the Yamuna river. A tributary is a stream or river that flows into a larger river or a lake.

The options provided are:

• Giri river
• Tons river
• Bata river
• Tangri river

Analysis of Potential Yamuna Tributaries

We will examine each river to see if it is known to be a tributary of the Yamuna river.

• Giri River: The Giri river is a major tributary of the Yamuna river. It originates in Himachal Pradesh and flows through the state before joining the Yamuna river.
• Tons River: The Tons river is the largest tributary of the Yamuna river. It also originates in Himachal Pradesh and is known for its significant water volume. It merges with the Yamuna downstream.
• Bata River: The Bata river is another tributary of the Yamuna river. It flows through Himachal Pradesh and Haryana before meeting the Yamuna river.
• Tangri River: The Tangri river is a river that flows through Haryana. It is part of the Ghaggar-Hakra river system, not a direct tributary of the Yamuna river. It originates in the Sivalik Hills and flows towards the south.

Summary of River Status

Based on the analysis, we can summarize the status of each river with respect to the Yamuna river:

From the summary table, it is clear that the Giri river, Tons river, and Bata river are tributaries of the Yamuna river, while the Tangri river is not.

Therefore, the river that is not a tributary of the Yamuna river from the given options is the Tangri river.

Additional Information: Understanding River Systems

The Yamuna river is one of the major rivers in India and is the largest tributary of the Ganges river. It has several important tributaries that contribute to its flow, including the Chambal, Sind, Betwa, and Ken rivers from the south, and the Tons, Giri, and Bata rivers from the north/hills.

River systems like the Yamuna and Ghaggar are distinct drainage basins. Rivers within one system typically join the main river or one of its tributaries, whereas rivers from a different system follow a separate course and drain into a different body of water or river system.
