Dredging the beds of rivers and extracting the sand from the bottom of it to obtain sand is one method besides desilting which any way is inevitable. River sand is perfect fit compared to other types of sand as it falls in the right index of having good roundness, fineness, density, water absorption, etc. Sometimes as seen in Western Australia ...
