Dredging Significance in The World Today
The removal of silt and other materials from the bottom of water bodies is referred to as dredging. At the bottom of the lakes, harbors, rivers and water bodies is where you will find these sediments and debris which are to be removed. 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. A dredge is used in the process of dredging. 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 have the same use but their application is in different areas. Other purposes for dredging include mining sand, clay, or rock for construction, mining for gold and other valuables, reclaiming damage areas by oil spills and storms, clearing trash off the sea beds, providing materials for eroded beaches, and so on.
Dredging plays a vital role in a nation’s economy. This is as a bulk of imports and exports are transported into a country by the use of huge vessels which carry them. Dredging assists in avoiding the collapse of the economy by ensuring that there is no stoppage in the flow of activities by the ships. 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. Dredging is also important in reducing the exposure of fish, wildlife, and people to contaminants in the water and preventing further spread of the contaminants in other areas of the water body. 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 various sources that cause pollution include seawater 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. Many cities affected by exposure to rising sea levels and storm damages 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. Finances will be preserved as there will be little or no damages.
