Transferring of materials from an environment with water to another is referred as dredging. A special equipment called a dredger issued to carry out this activity. It is a floating plant operated in a specialized manner to carry out the functions. The activity is done aiming for different things. It is also done at different locations as required. Some useful materials can be recovered by this activity. It also is used for creating a bigger depth for water. This activity is done halfway under water or completely under water. The activity can hence be done whether in small water bodies or huge water bodies.
The process of dredging mainly involves four stages. It calls for the best skills to perform these processes for the best outcome. The process is inclusive of; loosening of the material, extraction by carrying the material to the surface, moving to a different place and disposing of it. Some mechanical processes are used in extraction but mainly suctioning is used. The disposal can be using the material constructively or putting it into infill sites.
Dredging provides a solution to maintaining the accessibility of the posts and other waterways. Land reclamation and protection of the coasts is enhanced through this process. The coastal regions develop and become better. This is done when the dredging machine brings together the sediments and transports it to another place. Materials which are of great commercial importance are acquired. They can be minerals of high-value materials like sand and gravel which are used for construction purposes. Capital dredging is the process that involves mining to acquire these materials; sand, clay or rocks. This work is best done by a heavy machine like a dredger.
Another crucial achievement of dredging is the land reclamation. This process creates more land from river beds, ocean margins, and lake beds. the process is engaging and involves piling of big rocks and materials extracted from the waters to control the water beds.
Beach nourishment is enhanced by the use of a dredge by replacing sand carried by storms or wave action. the recreational importance of a beach is maintained through this processes. Preventing floods is an activity done by use of a dredger. The dredger creates deeper pathways for the water during a heavy downpour. The equipment can also be used to create some blocks on the areas with much soil erosion to cab the problem.
A dredging machine makes it easy to extract unwanted materials from various water pathways and canals. Corpses and other important evidences are recovered by the law enforcement using a dredger. Some people use dredging to acquire clams and crabs which are edible. They grow edible marine creatures at some deep banks like oysters and harvest them.
