Dhala River originated from the eastern hills of tripura (India). Flowing north from its source the river enters Bangladesh through Kulaura upazila of Maulvi Bazar district and meets with the manu river southwest of Rajnagar upazila of the same district. The joint course of the Manu and Dhala flows towards Maulvi Bazar and turning north debouches into the kushiyara at Manumukh. [Md Mahbub Murshed]
