Dredging is excavation work carried out underwater or partially underwater, in shallow or ocean waters. It supports navigation of waterways and ports, and contributes to coastal protection, land reclamation and coastal reconstruction by collecting sediments and transporting them to other locations.
Sand and sediment collect and accumulate in marinas and harbors.
This can cause disruption to water communication, navigation of boats and yachts trapped due to shallow waters. Therefore, regular dredging work is necessary to ensure safe navigation.
The frequency and regularity of such cleaning and dredging work depends on environmental climatic factors and other circumstances.
