Abstract

The present study deal with the anthropogenic impact on morphology of Teesta river in Northern Bangladesh includes bridge and barrage, bank stabilization, artificial levees, human settlement on side of river bank, intensive agriculture, sand mining which poses various negative impact. Extensive field work was conducted from December 18 to December 27 in 2013 to observe environmental impact of anthropogenic activities in the study. In addition, water discharge data (1979 to 2008) were analyzed to show the recent situation of Teesta River. The result reveals that water discharge quantity has been significantly reduced at Dalia point of Teesta River. The study also shows that excessive control of water discharge of Teesta River by man-made structure makes this river useless for the study area people. Average water discharge of monsoon season and dry season is 994.73 and 71.20 cusecs respectively. Therefore it is not conclusive but the study suggests that Govt. should be taken initiative to reduce the anthropogenic impact on morphology of Teesta River in northern Bangladesh.
