Manu River  one of the trans-boundary rivers of Bangladesh and also a tributary of the kushiyara river. The Manu takes its rise under the Kahoisib peak of the Sakkanklang range located in the Hill Tripura (India) and for some distance passes through various narrow gorges with escarpments of naked rock rising often 30m and more, and cutting into deep and clear pools. As it descends into the more level plain, it becomes a broad sluggish stream with a meander course. Its course is northward until it reaches the Sylhet plains. The river enters Bangladesh through Kulaura upazila in Maulvi Bazar district, when it changes to northwest and north to meet the Kushiyara at Manumukh. [Md Mahbub Murshed]
