Dredging is the process of removing the sediment from a water body (reservoir or channel), transporting, and depositing it at another location far away. Generally, dredging is an expensive means of recovering the storage capacity unless the deposits removed can be used for beneficial purposes.
However, with the increase in water demand and reduction in the construction of new projects, it is expected that the number of incidents where dredging is taken up will increase. If you also require dredging services, then you must visit coastseawall.com/dredging/.
Dredging may be resorted to when other methods of sediment management are not viable or successful. It is also a good option for cleaning out sediment from water dams that need to remain operational. It is also more challenging from an environmental perspective, although it may be preferable to other options such as river diversions.
Dredging can be carried out without affecting the normal operation of the reservoir. If the area to be cleared is normally dry, the earth-moving equipment can be deployed. Sometimes, the reservoir is specifically emptied for this purpose.
Dredging (underwater reclamation) is expensive due to the high cost of the equipment required to carry out this work as well as the variability of the solids concentration that is associated with the variable cutting rates.
