Understanding the Indus River System and its Tributaries

The question asks us to identify a specific river among Chenab, Jhelum, Ravi, and Sutlej within the Indus river system. The condition is that this river receives the water from the other three rivers and then flows directly into the main Indus River.

Analyzing the Indus River Tributary Connections

Let's examine how these rivers join each other in the Indus basin:

• The Jhelum River flows into the Chenab River.
• The Ravi River flows into the Chenab River.
• Thus, the Chenab River carries the combined waters of the Jhelum and the Ravi.
• The Chenab River then joins the Sutlej River.
• The Sutlej River also receives the Beas River (though the Beas is not listed in the options, its confluence with the Sutlej is significant).
• The Sutlej River, now carrying the waters of the Jhelum, Chenab, Ravi, and Beas, flows into the main Indus River.

Based on this flow pattern, the Sutlej River is the one that receives the combined flow from the Chenab (which already contains Jhelum and Ravi's waters) and then directly joins the Indus River.

Identifying the River Joining Indus Directly

The question specifies that three rivers pour into one, which then joins the Indus directly. Following the flow, Jhelum and Ravi pour into Chenab, and Chenab pours into Sutlej. Therefore, Sutlej receives the combined flow of Jhelum, Ravi, and Chenab. The Sutlej is the river from the list that joins the Indus River directly.

The final answer is the river that receives the combined flow of Chenab, Jhelum, and Ravi and then joins the Indus directly. This river is the Sutlej.

Therefore, the river that fits the description is the Sutlej.

Additional Information on Indus River Basin

The Indus River system is one of the largest river systems in the world, originating in the Tibetan Plateau and flowing through India and Pakistan before emptying into the Arabian Sea. The five major eastern tributaries, collectively known as the 'Panjnad' (meaning five rivers), are Jhelum, Chenab, Ravi, Beas, and Sutlej. These five rivers eventually merge and flow into the Indus River at Mithankot, Pakistan.

Understanding the confluence pattern of these rivers is crucial for grasping the geography of the region. The Sutlej is the southernmost of the five eastern tributaries and plays a critical role as it collects the waters of the Chenab (and thereby Jhelum and Ravi) and the Beas before meeting the Indus.
