Betna River
The Betna River is located in Bangladesh. It originates in Jessore District, flows through Satkhira and Khulna, where it is called Kalia River, and forms a branch called Dalua River. The Kalia is a tributary of the Kobadak River. The Betna changes its name to Arpangachhia River when it reaches the Sundarbans [Reserve Forest|Sundarbans], and changes it again to the Malancha before flowing into the Bay of Bengal.
