In fact, Dredging is a well-established craft involving floating equipment to deepen, create or maintain waterways, for commercial shipping and navigation, and for other purposes, such as hydraulic mining, landfill and reclamation, and environmental protection. It has developed from an art to a sophisticated hydraulic engineering technique, involving specially designed dredging vessels, pumps, and pipelines. The scientific investigation goes hand-in-hand with practical engineering over a worldwide enterprise in improving humankind’s water-based living conditions.
