Dredging Significance in The World Today
Dredging is the excavation of silt and other material from the bottom of bodies of water. The sediments and debris are removed from the bottom of lakes, rivers, harbors, and other water bodies. With this, sand and silt that wishes downstream can be unblocked. 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. The activity of dredging requires and equipment called dredge. There are many dredging equipments that are used, and they are dredgers like the cutter suction dredger, hopper dredger, trailer suction hopper dredger, clamshell dredger, hydraulic dredger, suction dredger, reclamation dredger, just to name a few. The equipment is used for the same purpose but in particular water bodies. 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.
A nation’s economy requires dredging as it plays a vital role. This is as a bulk of imports and exports are transported into a country by the use of huge vessels which carry them. Any hitches in between might cause the economy to collapse, and that is where dredging comes in. Vessels are able to stay afloat and avoid reaching the bottom by the help of the various dredges which sustain the right amounts of water required. It is important for the depth of the water to be sustained or added because of the size increase in the vessels that are sent into the waters 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. The pollution of water bodies from the influx of contaminated sediments that come in from cities and industrial sites has necessitated the need for dredging. The pollutants come in from sources such as sewer overflows, municipal and industrial discharges, and spills. Dredging helps to correct the damage caused by adverse weather conditions and increasing climate changes. Many cities have been affected by exposure to increasing sea levels and damages from storms, and thus they require dredging for reclamation. In order to maintain ports, dredges play a key role. It is better to have a dredging system in place than wait for damages to occur for action to be taken. This will save on costs that would otherwise have been incurred due to damages.
