The North Eastern Region represents a unique geophysical and ecological setup vis-a-vis the eastern Himalayas dominated by extremely dynamic earth processes, intensely potent monsoon rainfall regime, hyperactive seismicity and a fabulously rich biological and cultural diversity. The region is richly endowed with a vast water resource potential accounting for about one-third of the country’s total water wealth although its utilization has so far been grossly limited. The Brahmaputra, a transboundary river originating in Tibet (China) and one of the world’s largest and most complex alluvial river systems, drains a major part of the region. The Barak is another dominant river system flowing in the southern part of the region that eventually flows across the border to Bangladesh. The floodplains of these rivers are dotted with a large number of wetlands (locally known as Beels) that have considerable ecological, hydrological as well as economic significance. However, most of these wetlands are in degraded or derelict condition due to accelerated sedimentation, eutrophication, encroachment and various other anthropogenic factors. The study discusses different aspects of fluvial geomorphology in relation to the geologic and geotectonic frameworks of the region. An integrated basin planning and management approach seems to be the most appropriate paradigm for utilizing the vast water wealth of the region and mitigating its associated hazards. The geologic/geomorphic ideas and techniques are increasingly known to have great relevance in the management and conservation of rivers and other water bodies like wetlands, especially in the context of North East India.
