Abstract:
The Kosi River is known as one of the most dynamic river systems. Even smaller interfan rivers joining the Kosi River at downstream reaches are also characterised by frequent channel migration. Avulsion process is responsible for dynamic nature of these rivers. An in-depth process understanding of such geomorphic processes is required to manage flood hazards along aggrading river systems. New conceptual advancement in geomorphic studies supported with significant enhancement in remote sensing and surveying techniques will help to develop future strategies for sustainable management of such dynamic rivers.
