A Study on Soil Erosion in Pasighat Town (Arunachal Pradesh) India

Pasighat which lies on the foothills of the Himalayas is one of the important townsof Arunachal Pradesh. A very turbulent river named Siang flows through the townand causes frequent flash floods, inundating the low-lying areas. This river and townis also under threat due to continuous soil erosion. This soil erosion affects theneighbouring state of Assam as well. Due to the soil erosion this river known asBrahmaputra in Assam is constantly changing its course making a large numberof water channels with sand bars thus inundating vast cultivable land every year.The study analyses the cause of the problem at Pasighat in the backdrop of theexisting river system, morphology and the geographical evolution of the TransHimalayas.
