Change detection of exposed sandbars around Kaziranga national park

Spectral signature based post classification change detection approach is applied to identify the changes in Brahmaputra river along with sandbars around Kaziranga National Park in Assam, India. Landsat 5 images from 2006 to 2011 are used and the results are compared with the annual rainfall of the region to identify areas that are erosion prone. From the results it is observed that the amount of sandbar in the Brahmaputra River is inversely proportional to the annual rainfall of the region. The preliminary results presented in the paper will further help for a more detailed identification of erosion prone areas around the Kaziranga National Park which is largely affected by flood during monsoon season.
