Introduction,Among these, indiscriminate sand and gravel mining from the active channels and floodplains are the most disastrous one as the activity threatens the very existence of the river ecosystem. The problem is acute in small rivers that have limited catchment area (<10,000 km.) and river sand and gravel r

Furthermore, the extraction of this granular material is unavoidable as the sustainability of construction industry depends heavily on it. In rivers, construction grade sand occurs in different sources—active channels, floodpl

Among the various human interventions that are threatening rivers, indiscriminate river sand mining is of paramount importance as the activity irreparably degrades rivers and its adjoining aquatic environments. Studies reveal that the river bed in their storage zones is
