To Study the Channel Migration Pattern for Realignment of Amochhu River

Abstract

River systems have had a complex profile of detailed investigation and research work. A detailed study of a river system profits human with many natural resources that can be exploited and utilized. Limited studies carried out along the river stretch earlier were for flood mitigations and river training feasibilities. The river's behavior poses threat to livelihood in the current city and a quantifiable solution to the growing demand of land needs to be addressed. In order to accomplish the objectives, satellite photographs of different years were compared with the satellite photographs concluding that the river in itself was adjusting to its stability along the course of time. With respect to the normal discharge observed, the river system a suitable channel is delineated for the normal flow condition. On the other hand, a huge channel is assigned for accommodating the worst flood situation. These channels are supported with safety measures of standard river training structures suitable for the river system. With the installation of such channels along the river bank, a huge amount of land can be reclaimed to meet predicted land demand of the growing Phuentsholing city and safety concerns.
