Abstract

Sand is one of the most important non-living resource/mineral formations on the earths surface. The sand formation is recorded only in the recent ages of the earths history. Sand has become a very important mineral resource in our society due to its applications in various fields. Sands of river streams have no substitute for use as building material in reinforced concrete cement. It can be used for making concrete, filling roads, building sites, brick-making, glass industries, sandpapers, reclamations to replace eroded coastline etc. Efforts have been made to evaluate IRS-1D, PAN+LISS-III of False Color Composite (FCC) through Visual Image Interpretation Techniques (VIIT) using GIS softwares. The whole study area is drained by Cauvery and Kabini river basins that carry sand from different locations and deposits largely at meandering. Especially, Talakadu area has massive deposits of sands on the windward side of river. It covers sand dunes in the river bank by the fault running through the river Cauvery. Rapid urbanization is the major cause for sand demand and is responsible for unsustainable extraction of sand from dried river paths. Currently sand extraction is permitted up to three feet, but it is being dug up even up to 25-30 ft which later fails the possessing irrigation wells. Production of adulterated sand is a mixture of sand from estuary and coastal land that are gradually increased due to high cost of sand. It is a growing imbalance as prevailing uncontrolled sand mining and its adulteration continues to cause significant environmental damage and socio-economic problems. A complex interaction between economic, demographic, social and political encouragement are required to avoid the adverse effects of sand mining on riverbed environments. The final results highlight the impacts of environment and its management in Cauvery and Kabini river basins of Mysore District, Karnataka, which is a suitable model in similar geological conditions.
