CORE Indus Basin and the Punjab Tributaries
Indus river system and five Punjab tributaries is the north-west drainage anchor for India. NCERT names the Panjnad set as Satluj, Beas, Ravi, Chenab and Jhelum, and the Indus Waters Treaty of 1960 separates the western rivers, Indus-Jhelum-Chenab, from the eastern rivers, Ravi-Beas-Sutlej. This legal split matters for geography because rivers, canals and political boundaries do not follow the same logic. The Sutlej-Beas side feeds canal systems that carry water toward Rajasthan's arid north-west, so Sri Ganganagar and Hanumangarh agriculture is tied to a Himalayan basin outside Rajasthan. The Indus course also shows why a drainage basin can be physically continuous while its water management is divided by an international border. Glacial and snow-fed upper reaches make the system perennial, but downstream use depends on barrages, link canals and allocation rules. For a map question, Jhelum and Chenab stay on the western side, Ravi and Beas sit in the middle Punjab belt, and Sutlej is the easternmost large Punjab river before it joins the broader Indus network through the plains. The Rajasthan lens is therefore not a local river origin; it is transferred water, canal irrigation and desert settlement. The basin also demonstrates antecedent Himalayan drainage: upper channels cut hard mountain barriers before entering broad plains. Punjab tributaries have high strategic value because a change in one headwork or barrage can alter irrigation delivery far from the mountain source. This is why the Indus example should be read as physical geography plus water administration. It joins glacier supply, alluvial plains, canal command areas, border politics and desert farming into one connected drainage case. The same names also appear in many ordering problems, where the wrong answer shifts Chenab or Ravi into the wrong side of the Punjab sequence. A reliable map image places the tributaries in a north-western fan rather than in the Ganga plain or the peninsular plateau.
