Dohan Stream: Unraveling its Tributary Link to the Sahibi River

The question asks to identify the main river of which the Dohan stream is an important seasonal tributary. Understanding the geographical context of rivers in North India is key to answering this.

Understanding the Dohan Stream

The Dohan stream is recognized as a significant seasonal stream. This means it primarily carries water during specific times of the year, often linked to monsoon rainfall or snowmelt, and might be dry for parts of the year. It originates in the hills of Rajasthan and flows through parts of Haryana.

The Sahibi River Connection

The Dohan stream is a major tributary of the Sahibi river. The Sahibi river is itself a prominent seasonal river, historically flowing through Rajasthan and Haryana, eventually reaching the Yamuna river. The confluence of the Dohan stream significantly contributes to the water flow of the Sahibi river, particularly in the lower reaches.

Analyzing the Options

Let's look at the provided options:

• Markanda: The Markanda river is another seasonal river in Haryana and Himachal Pradesh, often considered a tributary of the Ghaggar river, not the Sahibi.
• Sahibi: As established, the Dohan stream is a key tributary of the Sahibi river. This aligns with geographical records.
• Ghaggar: The Ghaggar river is a major intermittent river in the region, flowing through Himachal Pradesh, Punjab, and Haryana. While related geographically, Dohan doesn't directly feed into Ghaggar as its primary course.
• Saraswati: The mythical Saraswati river's course is debated, but it's generally believed to have been a larger, ancient river system potentially linked to the Ghaggar or flowing independently. Dohan is not considered its tributary in the modern context.

Conclusion

Based on geographical information, the Dohan stream's primary role is as a tributary to the Sahibi river. Therefore, the Sahibi river is the correct answer.
