Guwahati, July 15: Erosion of the banks of the river Brahmaputra all over the state has created havoc and according to the Flood Control Department officials, massive deforestation, particularly in the neighbouring country Bhutan and Arunachal Pradesh is one of the main reasons for the problem. Though two waves of moderate floods hit Assam so far this year, fortunately the floods did not cause much damage till now and erosion of the banks of the river Brahmaputra has turned out to be the main problem. Sources said that different parts of the State have been affected by the problem of erosion this year. In Kamrup district, a part of the embankment of the river Brahmaputra was eroded away at Alikash near Chaygaon recently and efforts are now on to protect the embankment from further damage.
