Abstract
Burhachapori Wildlife Sanctuary (BWLS), situated within the actively migrating floodplains of the Brahmaputra River in the state of Assam, represents one of the most geomorphically unstable protected areas of the Brahmaputra valley. This study reconstructs multi-decadal patterns of riverbank erosion and deposition along the sanctuary's northern boundary between 1979 and 2020, integrating Landsat time-series imagery, Survey of India topographic sheets and field observations. The results reveal a cumulative loss of 10.342 sq. km of landmass, driven by sustained cut-bank retreat, channel migration and mid-channel bar dynamics, while depositional processes contributed only 0.51 sq. km of land gain, primarily along hydraulically quiescent zones. Erosion was most severe along the Paspati, Jhaoni and Basabari sectors, where anthropogenic infrastructure such as anti-poaching camps was repeatedly destroyed. Emergent river islands (chars) within the sanctuary were temporarily occupied by fishing groups until formal reclamation after 2013, following which notable increases in the presence of Platanista gangetica and wintering anatids were recorded. The findings exemplify the sensitivity of floodplain protected areas to fluvial processes and demonstrate the need for geomorphologically informed conservation planning. The study offers a baseline framework for integrating hydro-geomorphic dynamics into management strategies for riverine protected areas in monsoon-dominated braided-river systems.
