Wetland comprises several functions including flood and sediment control, groundwater storage, irrigation, fishery, habitat of wild life and recreation. Although wetlands in developing countries will be potentially developed, quantitative evaluation of wetland functions are essential to manage such multi functional areas appropriately. In this paper, flood and sediment control functions of wetlands in Kushiyara River Basin, northeast region of Bangladesh are examined through field investigations and by use of observed hydrological data. The results quantitatively show significant effects of flood control and sedimentation in the wetlands.
