“…Therefore, the proposed impact assessment framework will be more effective by evaluating livelihood assets of community people (Scoones, 1998;Ellis, 1999;DFID, 2000), the performance of TRM operation and its institutional set up. By providing strengths and opportunities or weaknesses and threats information (Nazer, 2009;Beckanov, 2010), the benefits will come from a group of ecosystem services by trade-offs (Falkenmark, 2003;Tallis et al, 2008) and by properly monetarising an ecosystem service (Springate-Baginski et al, 2009;WMO, 2012;Schagner et al, 2013;Hossain et al, 2016) with both economic and environmental value to understand risks or opportunities than those of mentioned frameworks. Sixthly, the framework will project the future vulnerability focus on water supply, ecological assessment and disaster risk reduction (Sullivan, 2010;Gain et al, 2012a;Doczi, 2014;Vollmer et al, 2016) by rainfall and weather forecast (Wu et al, 2010;Chau et al, 2010;Pallavi and Singh, 2016;Vivekanandan, 2016) as well as rainfall runoff predictions (Walker et al, 2014;Sarkar and Kumar, 2012;Mittal et al, 2012) for water-logging in the floodplain area, sediment and water flow forecast (Mostafa et al, 2012;Krishna et al, 2010;Shabani and Shabani, 2012) for drainage congestion of the tidal river and rising sea levels projections (Pashova and Popova, 2011;Rafiean and Aliei, 2013;Goharnejad, et al, 2013) for the floodplain community, tidal river and Tidal Basin.…”
