DREDGING

Cleaning, deepening, or widening of a waterway, using a machine (dredge) that removes materials by means of a scoop or a suction device. The process of dredging works by eliminating silt and other substances from material that are found at the bottom of water sources. As silt and sand are cleansed downstream, sedimentation eventually inflates harbors and channels. As a result, dredging is considered as the eradication of debris and sediments from the bottom of large water bodies such as rivers, lakes, harbors, etc.
