Tipaimukh dam will have a serious, adverse impact on the downstream part of the Barak river basin, which is in north-eastern part of Bangladesh, and known as Surma-Kushyiara-Meghna river basin. It will severely affect Hydrology of that area due to release and blocking of water as per India's need. As a result, BD will have more water when it will not need it (i.e. during flood season), and will not have adequate water when it will need it (i.e. in dry/draught season). Inundation Pattern and River-Floodplain-Wetland Ecosystem in Sylhet and Moulvibazar area will be seriously hurt. Bangladesh's morphology will be adversely affected due to excessive river erosion in Barak river, Surma-Kushiara river and in Kalni river. Dam break and similar disaster will cause initially 25 meter water depth in Barak river, Surma-Kushiara river and in Kalni river along with many areas in Sylhet district. The entire area is earthquake prone and probability of earthquake will increase manifold in that area due to artificial blocking of water by India.
