Channel Migration and Its Impact on Habitable Area of Lower Reach of River Manas in Assam, India

ABSTRACT

This study examines the implications of channel migration on the habitable area of the lower reach of the Manas River in Assam, India. The research aims to address the erosion and deposition processes associated with the movement of the river channel. A sample size of 359 geographical areas near ten villages located along the riverbank was selected for the study. The research utilizes a literature review to under-stand the socio-economic impacts of the geomorphological system of the Manas River. The Brahmaputra River, of which the Manas River is a major tributary, also plays a significant role in the geomorphological processes of channel migration in the region. Climate change and human activities are identified as factors influencing channel migration and the habitable and cropped areas along the river. Regression analysis reveals a significant relationship between channel migration and the habitable and cropped are-as. The study concludes that channel migration in the Manas River has substantial implications for the region geographical and socio-economic aspects. It underscores the need for comprehensive research utilizing GIS and remote sensing techniques to understand and effectively manage channel migration. The findings emphasize the importance of adopting sustainable development practices and preserving the ecological and socio-cultural significance of the Manas River.
