Dredging is done by carrying materials from one place that contains water to another. This activity is done by a special equipment referred to as a dredger. It is a floating plant operated in a specialized manner to carry out the functions. The activity of dredging is done with different purposes. It is also done at different locations as required. Majorly this activity is done so as to get materials which are important. 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. This processes must be done in the correct follow-up and professionalism to ensure of its success. 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. suctioning is the main method of extraction or other mechanical processes. The materials are disposed of by being subjected to better use or put into infill sites.
Dredging provides a solution to maintaining the accessibility of the posts and other waterways. This assists in the protection of the coasts and reclamation of land. The coastal regions develop and become better. This process is made effective by the transportation of the sediments to other place leaving the coastal area clear. Materials which are of great commercial importance are acquired. Materials like sand and gravel can be extracted which of importance in the construction industry. The acquisition of these important materials like clay, sand, and rocks through dredging is called Capital dredging. This work is best done by a heavy machine like a dredger.
Land reclamation is another important reason for dredging. This is the process of creating some new land from river banks,lake beds or oceans. This is an involving process that involves extracting material like heavy rocks and stacking them at the banks so as to control water flowing towards the banks.
Beach nourishment is enhanced by the use of a dredge by replacing sand carried by storms or wave action. Through this the recreational importance of the beach are maintained. Preventing floods is an activity done by use of a dredger. It digs deeper in the water channels which creates a pathway for the running water during heavy rains. It can also carry materials like sand and stock it at areas with heavy soil erosion to reduce the erosion.
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.
