The Value of Dredging in The Current World
The removal of silt and other materials from the bottom of water bodies is referred to as dredging. The sediments and debris are removed from the bottom of lakes, rivers, harbors, and other water bodies. This is necessary to unblock the waterways which have been filled by sand and silt that is washing downstream. The purpose of dredging is to ensure the safe passage of boats and ships by sustaining and increasing the depth of navigation channels, anchorages, and berthing areas. A dredge is used in the process of dredging. There are different types of dredges, and they are the cutter suction dredger, hopper dredger, trailer suction hopper dredger, clamshell dredger, hydraulic dredger, suction dredger, reclamation dredger, etc. The function of these equipment is the same but in specific waterways. Dredging has other uses which are mining sand, clay, or rock for construction, mining for gold and other valuables, reclaiming damaged areas by old settlers and storms, clearing trash off the sea beds, providing materials for eroded beaches, among others.
Dredging plays a vital role in a nation’s economy. This is due to the large ships that carry and transport goods which have been imported or exported into and out of a country. Dredging assists in avoiding the collapse of the economy by ensuring that there is no stoppage in the flow of activities by the ships.Dredges help provide the right amount of water that vessels require to float and not touch the bottom. They also maintain an increase water depth as larger ships are deployed over time. It is possible to minimize the exposure of fish, wildlife, and people to contaminants in the water and to stop more spreading of the contaminants in other areas of water bodies by the use of dredging. Water pollution caused by cities and industrial sites that bring in contaminated sediments makes it necessary to carry out dredging. There are different sources that cause pollution which are sewer overflows, municipal and industrial discharges, and spills. Adverse weather conditions and increasing climatic changes cause a lot of damage which can be corrected by dredging. Reclamation is needed as a result of rising sea levels and storm damages which have affected many cities. Dredges are vital to port maintenance. Other than wait for damages to take place for people to be in action, having a dredging system in place is beneficial. Since the damages that would occur would be mitigated, a lot of money will be saved.
