What is dredging? In which port is it found?

Hint:
As larger and larger ships are deployed, the water depth continues to increase over time. Since large ships carry large quantities of goods imported into the country, dredging plays a vital role in the country’s economy.

Complete solution:
 Dredging refers to the removal of sediments and debris from the bottom of lakes, rivers, harbours, and other water bodies. This is a daily necessity for waterways around the world because sediments (the natural washing process of sand and silt downstream) gradually fill rivers and ports.

 Dredging often focuses on maintaining or increasing the depth of the channel, anchorage, or berthing area to ensure the safe passage of ships and ships. Ships need a certain amount of water to float without bottoming.

Dredging can also reduce the exposure of fish, wildlife, and humans to pollutants and prevent pollutants from spreading to other areas of the water body.
Dredging ports: Dredging often focuses on maintaining or increasing the depth of the channel, anchorage, or berthing area to ensure the safe passage of ships and ships. Silt accumulates rapidly in Indian ports, and dredging is required throughout the year to maintain navigation depth.

 In the port construction work, the dredger needs to perform some activities, the most important of which is deepening and excavation. Providing adequate depth of access, navigation channels and harbour basins are essential for continued survival as a port.

Note:
Sparse normally refers to increasing the depth of the river channel by removing the silt accumulated over the years. Excavation is usually carried out with a vacuum barge or excavator fixed on the embankment.
