Flood characteristics of upper meghna river Basin, Bangladesh

This paper presents the outcome of a research study conducted to analyze the propagation time of the flash floods in the Upper Meghna river basin in Bangladesh and corresponding socio-economic impacts. A numerical model set-up in the general river model system named MIKE 11 was applied to simulate flash floods in the river basin and the travel time of their flood peak from the border towards India (only limited information is available from inside India) and into North East region. The results reveal that there is only little warning time from the time the flood passes the border towards India and until the flood impacts the rural people in the North East region of Bangladesh. The corresponding socio-economic impacts were quantified and found to be substantial.
