Effect of Hydrological Modification on Wetland Morphology in Reference to Parts of the Bagri Region of Eastern India

The previous existing literature concentrated majorly on how mounting anthropogenic pressure invited hydrological evolution and morphological insecurity in the wetlands. In the floodplain region where the wetlands confronted severe threats in the form of agricultural expansion, built-up encroachment, etc. and resulting hydrological evolution is immensely obvious, how far the hydrological parameters can control landscape insecurity was not well addressed. Therefore, the present work endeavored to identify the association between hydrological parameters and wetland landscape fragmentation. Results exhibited on average 55% of the wetland area was vulnerable to fragmentation, whereas a huge areal coverage, i.e., nearly 69% for water presence frequency (WPF)Water presence frequency and > 90% in the case of Wetland depth comes under an insecure hydrological area. A large area converted from wetland area to land area. A negative association was found between hydrological stability and morphological instability. Poor hydrological condition reinvigorates the morphological insecurity of the wetland as the anthropogenic pressure made the outer area more vulnerable and prevented the wetland to maintain desired hydrological stability.
