Sunderban forest is shared between Bangladesh and India, it is the world’s largest, continuous coastal wetland. It covers an area of about one million hectares in the delta of the rivers Ganges, Brahmaputra, and Meghna. Enormous amounts of sediments carried by the river system contribute to the expansion and dynamics of this delta. The Sunderban area experiences subtropical monsoonal climate with an annual rainfall of 1,600–1,800 mm and occasional severe cyclonic storms [2]. The maximum elevation within the Sundarbans is only 10 m above the mean sea level. The western and eastern limits of the Sundarbans are defined by the course of the River Hooghly (a distributary of river Ganges) and River Baleshwar, respectively. About 60 % of the mangrove forests lie in the Khulna District of Bangladesh and the rest in the 24-Paragnas District of West Bengal (India). A large number of channels and creeks flow into larger rivers in the Sundarbans. The Sundarbans, shared between Bangladesh and India, is the world’s largest, continuous coastal wetland.

A large number of channels and creeks flow into larger rivers in the Sundarbans but due to cyclonic proned area it is always comes under cylonic attack and a large damage of life and property is seen .so for this situation to handle there must be some steps to taken and also for improving their livelihood .
