Impact Assessment involves characterizing the impact in terms of its likely nature, duration, frequency, reversibility and magnitude. Finally a judgement must be made as to whether the impact is likely to be significant or not. A large number of impact analysis techniques exist, each have their advantages and disadvantages.

The impact of mining is leading to the major issues, like a threat to the entire environment and also damaging the health of all life on Earth. Mining procedures generally require a larger and vast area of land. Deforestation is a by-product of mining and the build up of the mining areas requires constructing roads and residences for the mine employees and often vegetation farms are abolished.

Sand mining has a number of effects on the river environment. Sand mining disturbs and completely destroys the habitat in mined areas. It causes changes in the river's channel form, physical habitats, and food webs - the river's ecosystem. It also increases the velocity of the flow in the river, which destroys the flow regime and eventually erodes the river banks.
