In the past few years, dredging companies across the world have picked up a bad reputation due to haphazard and careless practices combined with an unwillingness to consider the environment in which they are excavating.

Here are a few reasons why dredging is necessary, how this practice can be beneficial, and how it should be done correctly. 

New call-to-action

1- Helps to protect against the effects of coastal erosion

Like we talked about in our last post, coastal erosion is a process that breaks down the coastline. When something like a hurricane, cyclone, or tropical storm makes its way inland, it displaces the sand and sediment around the beach and deposits it elsewhere, usually in awkward places like sandbars located fairly far away from the coast.

As the water line creeps closer to the towns and inhabited areas, the risk of problematic flooding and damaging storms affecting the area begins to rise as well. The distance that the beaches create between the water and the towns serves as a protective barrier. If this distance doesn’t exist, the towns and infrastructure become more vulnerable.

Inland dredging combats against coastal erosion by depositing sand and sediment in places where erosion is most substantial. This effectively adds to the land and helps buffer against the effects of strong storms and flooding. When ocean dredging, it’s considered best practice to deposit sediment that is safe and uncontaminated so as not to disrupt the environment in that area. 

2- Habitat restoration

Similar to coastal erosion, strong storms could also disrupt marine and beach habitats which often exist in the surrounding sand or gravel. When the habitats are disrupted, the wildlife is forced to relocate. This can cause issues in surrounding towns and can also put the wildlife at risk.

Inland dredging serves as a way to safely maintain the environments where the plant and animal life inhabits. Again, it’s especially crucial to only use dredged material that is safe and free of contaminants.

Dredging companies, when doing their job properly, pick up materials from specific areas and transport them to places that have been affected by storms and strong waves. Basically, it recreates the sand and dunes that have been eroded or destroyed.

3- Making marinas possible to navigate

One of the most prominent ways to import and export products is via ships and boats. When these vessels make their way inland, they dock at marinas. Because marinas are so close to land, they’re not nearly as deep as other parts of the ocean located farther off the coast.

Sometimes, the sediment at the bottom of marinas begins to concentrate in certain areas, making it difficult for ships and boats to navigate without getting stuck. That’s where dredging comes in.

Dredging companies either scoop or suck up the sediment and transfer it elsewhere. When doing this, it’s very important to not transfer materials such as garbage or contaminants, so as not to harm other environments.

4- Recycles contaminants

At this point, you’re probably wondering what dredging companies do with the material that is contaminated. One of the best uses for contaminated sediment is to actually turn it into useful objects. Something that we regularly see is using the material to construct concrete and gravel. Not only is this a safe alternative to depositing the material in other areas, but it also takes out the polluted sediment from the marina.

There are quite a few reasons why it’s necessary to dredge, as long as it’s being done safely. Following protocols and never skimping on proper safety steps is important, especially when dealing with precious and fragile wildlife. 

5- Assist the mining industry

Dredging technology has grown more precise and more compact. This means that now dredge operators can now use smaller suction cutters or hydraulic dredges to displace mined materials and sort through them for gold.

In some cases, some miners make use of small backpack-sized dredges to quickly clear through material that larger machines would not be able to access.
