You will be able to quickly grasp the process of dredging if you have heard about sedimentation in rivers and lakes. Simply put, sedimentation refers to the accumulation of silt, sand, and other debris at the bottom of a water body. Water contamination can be caused by excessive sediment buildup.

Dredging is a method that removes sediments from the banks or bottom of water bodies. The marine dredging services allows ships to pass more easily through the waterways. Underwater excavation is an integral part of waterway construction projects such as docks and bridges or underwater tunnels.

Let's now look at the different types of dredging and how it works.

Dredging Process

Dredging is the use of special equipment called dredges to remove undesirable sediments. It uses a vacuum to lift and pump out sediment from the bottom of water bodies. How does the dredge actually work in this process?

These are the steps involved in the dredging process.

  • The operator lowers a dredge boom until it reaches the bottom of a body or side of the water.
  • The rotating cutter-bar then uses its teeth to remove the sediments or debris.
  • Submersible pumps will remove sediment from the waterway’s bottom.
  • The dredge will then move the debris and sediment away for final processing.
