Not everyone has a clear idea about dredging. It is mostly thought to be a dirty job to clean up a harbor basin, and most land dwellers do not realize the importance of dredging. Inhabitants of a coastal area or a river-estuary know better. They know that without dredging the navigation in ports and rivers will after a while not be possible. In context of Bangladesh it is more that navigation- it is about developing and increasing land for urban population.

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 purpose, 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. Scientific investigation goes hand-in-hand with practical engineering over a worldwide enterprise in improving humankind’s water-based living conditions.
