River embankment and recession of wetland: a study on barul beel in lower ajoy basin

River floods play an important role in keeping the vitality of the adjacent wetlands. In Lower Ajoy Basin, embankments have been constructed to prevent the flood and thereby to avoid the flood damages. It has put a barrier for water and materials exchanges in between the river and the wetlands as it prevents the frequent river spill on the floodplain. As a result the wetlands are losing their characters and suffering from the scarcity of water. In the present study, emphasis has been given to find out the relationship between embankment and recession of Barul beel (wetland).
