Chaj Doab

Chaj Doab (Punjabi: چَج دوآب), also known as the Jech Doab, is one of the main regions of the Punjab province in Pakistan. Punjab historically has been divided into regions based on its various rivers, since the name Punjab itself is based on the region's five main rivers. The word Chaj (چَج) is combination of first Punjabi alphabet of Chenab (چناب) and Jhelum(جہلم), "Ch" چَ and "J" ج. The Chaj Doab includes the area between the Jhelum and Chenab rivers, thus also known as Jech Doab. It lies on the southern fringes of the Kashmir valley. The Chaj Doab is smaller in area compared to the other doabs, such as the Rachna, and it has a moderately high population density. Its principal city is Sargodha.
