Sand mining generates extra vehicle traffic, which negatively impairs the environment Where access roads cross riparian areas, the local environment may be impacted 11 Sand Budget Determining the sand budget for a particular stream reach requires sitespecific topographic, hydrologic, and hydraulic information The second case is reported on May 11 in Rashtriya Jung Times a local news portal describing of mechanized instream sand mining and construction of a makeshift bund in river Yamuna around Nangla Rai village of Kairana block in Shamli district, Uttar PradeshYamuna facing illegal, instream mining during Instream sand and gravel mining is somewhat of a misnomer because this mining method does not allow for excavating machinery in the flowing portion of the stream This mining method would be more accurately described as a bar skimming mining operation Bar skimming is limited to the exposed portion of a gravel bar above the water line, within Sand and Gravel Permitting Missouri Department of

Suffice to say that the ongoing instream sand mining at Battor will in future pose both environmental and even socioeconomic challenges for Battor and other Tongu communities One may assert with certainty that the socalled lucrative river sand mining ongoing at Battor is illegal and it is not done scientifically despite the fact that it is Aromolaran (2012) studied the effects of sand mining activities of rural people on agricultural land in Agraian communities of Ogun state in Nigeria His work revealed that mining of sand and gravel on agricultural land is one of the alternative livelihood activities of the rural people in Nigeria and is now becoming an environmental issueEnvironmental Effects of Sand and Gravel Mining on Land Sand and gravel are widely used throughout the US construction industry, but their extraction can significantly affect the physical, chemical, and biological characteristics of mined streams Fisheries biologists often find themselves involved in the complex environmental and regulatory issues related to instream sand and gravel mining This paper provides an overview of information Instream sand and gravel mining: Environmental
