<p><strong>Abstract.</strong> Channel migration becomes the main characteristic of major rivers of Mohana-Macheli watershed of western Nepal. Study of river channel migration of major rivers of watershed using freely available remote sensing show that the channel has shifted to as high as 1000 meters from the original river path over the span of 9 years (2009–2017). The channel migration directly affects the land use and it has direct effect on the flood plain settlements of the study area. Cultivation of sugarcane in sand area is one of the mitigating measures of flood effects and prevent river bank erosion. The study shows that the area of sand is changing disproportionately in the region. This paper presents an enhanced change detection method of river channel migration using remotely sensed images and identification of sand area using classification and interpretation technique.</p>

The longtime sustainability of river channel in the natural process depends on the gradient, volume of water, sediment supply and deposition in the river. Naturally, rivers maintain balance of river channel in all stage of the cycle of erosion. However, human activity mainly sand and gravel mining frequently disturb the balance that has much impact on the river morphology. The Imphal River between Motbung to Awang Leikinthabi is one of the worse sand and gravel-querying regions in Manipur. Hence, the main aim of this paper is to assess the impacts of querying on riverine landform and surrounding environment by using Remote Sensing and GIS.
