Rivers, the most important life sustaining systems in tropics and subtropics, are under immense pressure due to various kinds of human interventions. 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 …

Abstract Mining of gravel for construction aggregate in California is regulated under the concept of 'reclamation', borrowed from open‐pit coal mines, which are recontoured and returned to productive use (such as agriculture) after mine closure. The concept works for dry terrace pits and can be adapted to creation of wildlife habitat in wet terrace pits.
