Another river of Bangladesh, the , flows through a low-laying coastal plain that borders the Bay of Bengal. This flat, marshy area is subject to flooding during the wet season. To control the flooding of this river, engineers built a across the river.

Feni, dam

Explanation:

The river Feni, originates from South Tripura, India, subsequently enters Bangladesh and finally opens into the Bay of Bengal. The river forms part of the India-Bangladesh border and it's water allocation has been a subject of dispute between the two nations.

Owing to the seasonal rains and cyclones, the low lying boggy area in Bangladesh through which Feni passes, which borders the Bay Of Bengal, was consistently flooded causing damage to life and property therein.

As a solution to the above mentioned issue, the engineers constructed a dam in the year 1985, which is now known as, "Feni Dam", thereby making the boggy low lying area fit for agriculture, in addition to avoiding frequent floods and disruptions.
