Transferring of materials from an environment with water to another is referred as dredging. The machine used for this purpose is called a dredger. Through a skilled operation this floating machine is able to carry out the activity. There are different reasons for performing dredging. This activity is done in various locations where needed. The main reason is to recover material of great importance. Creating a greater pathway for the water is another importance of t grudging. This activity is done halfway under water or completely under water. In that case, the process is either done in the shallow waters or in deep waters like oceans.
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. suctioning is the main method of extraction or other mechanical processes. The disposal can be using the material constructively or putting it into infill sites.
maintaining the navigability of the ports and other waterways is maintained through dredging. Land reclamation and protection of the coasts is enhanced through this process. It also enhances the growth of the coastal regions. The sediments that are found in this areas are removed and moved to other areas to enhance this. Dredging helps extract important materials that can be of commercial use. Materials like sand and gravel can be extracted which of importance in the construction industry. Capital dredging is the process that involves mining to acquire these materials; sand, clay or rocks. A dredger is best situated because it’s a process that involves hard materials.
Land reclamation is another important reason for dredging. This is the process by which land is created from ocean margins,river banks and lake beds, 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.
Replacement of sand carried by storms or waves in the beach helps in the nourishment of the beach. This protects the beauty hence the recreation function of the beach. 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. The dredger can be used to carry heavy blocking materials at places of heavy soil erosion to solve 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 certain species of fish and crabs are acquired through the method of dredging. Some people grow oysters and other edible marine creatures and they harvest them through dredging for consumption.
