Chaj (Chaj/JeCh) Doab lies between which two rivers?

The concept of 'Doabs' is crucial for understanding the geography of the Punjab region, where 'Doab' refers to the land between two confluent rivers. The name 'Chaj' (or Jech) is a portmanteau derived from the names of the rivers it lies between. Therefore, Chenab & Jhelum is the correct answer.

• The Doab between the Jhelum and Ravi rivers is known as the Rechna Doab (Ravi + Chenab, not Jhelum + Ravi).
• The Doab between the Chenab and Sutlej rivers would encompass multiple doabs, not a single named 'Chaj' doab.
• The Doab between the Indus and Chenab rivers is called the Sindh Sagar Doab.

The naming convention of these doabs helps identify the specific river pair.
