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.
