Change detection of exposed sandbars around Kaziranga national park

A study reveals that the extent of exposed sandbars in the Brahmaputra River near Kaziranga National Park, India, is inversely related to annual rainfall, suggesting increased erosion risk during wetter years. Researchers applied a spectral signature-based post-classification change detection method using Landsat 5 satellite imagery from 2006 to 2011 to track sandbar dynamics and correlate them with regional precipitation patterns. The findings highlight that higher rainfall correlates with reduced sandbar visibility, likely due to intensified flooding during monsoon seasons. This relationship provides preliminary insights into erosion-prone zones, offering a foundation for further analysis to mitigate flood impacts on the UNESCO-listed Kaziranga National Park.
