a river in India and Pakistan. The Chenab measures approximately 1,100 km in length and drains an area of 138,000 sq km. Originating in the glaciers of the Western Himalayas, it flows through a deep valley in India and over the plains of Punjab in Pakistan. The main tributaries are the Jhelum and the Ravi, below the influx of which the Chenab is called the Trimab. The Chenab empties into the Sutlej River (Indus River basin).
The Chenab is fed by melting firn fields and glaciers and by rain, mainly during the summer monsoon season. The water level rises from June through October and is low in winter. The mean flow rate at the point where the river flows from the mountains is 890 cu m per sec; lower it decreases owing to the distribution of water through numerous irrigation canals (about 200,000 hectares of agricultural land is irrigated ). Cities in the densely populated valley include Wazirabad, Chiniot, and Multan, all in Pakistan.
