Dredging is a sediment removal technique that is useful for a wide variety of applications. If you're interested in learning more about dredging in relation to your construction site needs, you should explore the various applications that dredging can be used for.
The following are six of the major tasks that dredging can help accomplish on construction sites:
Developing waterways and expanding upon them
Waterways are important for general transportation and for the transport of goods. Dredging can allow waterways to be created or expanded so that cargo can be efficiently transported from one location to another.
Existing waterways are sometimes not deep enough to allow sizable cargo vessels to reach their destinations. In this situation, dredging can be an efficient means of expanding waterways so that they can more effectively allow for the passage of adequately sized cargo vessels.
Maintaining the functionality of waterways
Some waterways need to be periodically dredged out to maintain their functionality over time. Sediment can gather naturally in some waterways so that accumulated debris can make the waterway more shallow.
In this case, dredging can restore a waterway to its original condition so that vessels can continue to pass through unhindered by accumulated debris and sediment.
Reclaiming contaminated waterways
Accidents can happen that allow harmful contaminants to accumulate on the bottom of waterways. These contaminants can include chemical debris, decayed plant life, runoff, and sewage. Dredging can help to remove contaminants and thereby restore the health and purity of waterways.
Preparing for construction projects
When it comes to construction around waterways, dredging can be an important part of site preparation. Dredging is an important part of constructing structures such as piers, docks, and bridges.
Replenishing beachfront areas after significant erosion
Over time, shores along rivers and oceans can become eroded due to situations including hurricanes, storms, mining operations, and other natural disasters. Dredging can then be an important means of replenishing land that has been lost from beachfront areas.
Shore replenishment can be important when it comes to supporting pre-existing structures and supporting local ecosystems.
Preserving aquatic ecosystems
When dredging is used to remove contaminants like sludge, trash, and decaying vegetation from marine landscapes, it is important in preserving aquatic ecosystems.
Another important ecological issue dredging can help with is eutrophication. Eutrophication occurs when nutrients proliferate due to runoff and the resulting excess plant life leads to oxygen deprivation. Construction site dredging can remove excess vegetation and thereby restore a healthy oxygen balance to aquatic environments.
