A sustainable solution to excessive river sand mining by
River-sand mining has risen dramatically in the last few decades to fulfil the need for concrete in the building sector. The sand in a river’s bed preserves its environmental equilibrium (Farahani and Bayazidi, 2017).Excessive river-sand mining for use as fine aggregate in concrete is responsible for riverbed degradation, which causes a February 11, 2021. The world’s largest extractive industry gets little attention. Each year up to 50 billion tonnes of sand and gravel known collectively as aggregate are mined from rivers, lakes, oceans and hillsides.
