Shoreline Protection Stabilization Techniques

The shoreline is an extremely significant area because it acts as an active habitat for wildlife and fish. 

Moreover, shorelines play a critical role in cleaning the stormwater runoff.

In this regard, shoreline protection is important because it gives much-needed integrity to the water’s edge and reduces erosion.

Shoreline Erosion

Shoreline erosion is a natural process that is quite common on the majority of lakes, rivers, and coasts. It is typically a gradual process and can become quite destructive over a period of time.

Modern inventions and techniques like geotextile installation have proven to be highly effective methods of shoreline protection.

Following are some of the major shoreline stabilization techniques:

 

Natural Vegetation

The natural vegetation present at the shorelines is usually highly beneficial in strengthening the structural integrity and preventing the land from breaking down. This is possible because plans that have deep roots are capable of binding surface protection.

Moreover, their branches play an important role in preventing erosions from rainfall and heavy storms. Therefore, such plants should not be removed from the shorelines.

 

Gentle Slopes

The slope of a natural shoreline is important to absorb the high energy of waves. Therefore, the slopes should be maintained in a suitable manner. If a steep slope is present on a shoreline, then the waves will crash directly into the shore and cause erosion.

 

Soft Methods of Shoreline Protection

Soft methods of shoreline protection include plantations and using vegetative mats to prevent the use of other heavy methods like geotextile installation.

However, strategies like geotubes installation have also become quite easy and affordable methods of shoreline protection.

 

Role of Geotubes Installation in Shoreline Protection

Geotextile installation is a modern and reliable method of shoreline protection. Geotubes have become quite common for breakwater applications in cliffs, coastlines, and other such areas in which erosion is taking place and shorelines are suffering from issues like storms, tides, and high energy waves. 

By geotubes installation in such areas, the shoreline is protected by adding an extra layer of barrier between the water and shoreline. Moreover, the geotextile breakwater tube is capable of retaining sand, silt, and various other particles which facilitate the shorelines in retaining their original sand output.

 

Working of Breakwater Geotubes

Breakwater tubes are essentially made up of durable filtering fabrics that can retain the sediments and allow water to flow via the geotextile tube.

Moreover, the stability of the geotubes is important for erosion control so the tubes can be used on shorelines and coastlines to prevent beach erosion.

Most people and organizations find breakwater geotubes installation to be a highly efficient and cost-effective method of shoreline protection because it has greater durability than most of the other shoreline stabilization techniques.

The shoreline protection techniques are not limited to only geotextile installation. Instead, there are many other softer approaches that can be used to stabilize the shorelines.

 

Re-Vegetation

Re-vegetation is suitable for bare shorelines that are suffering from moderate erosion. If the shorelines are facing severe erosion, then you should not depend on this method.

It basically includes re-planting the natural vegetation that will provide extra stability to the shoreline. It is a very reliable shoreline protection technique because it is highly affordable and can easily be performed by the landowner.

 

Live Staking

Live staking is another simple technique of shoreline stabilization that is suitable for areas that have slopes with light erosion.

However, it can also be used in areas of heavier erosion by combining with other methods like geotubes installation. It involves installing the cuttings of woody plants directly deep into the ground to let them grow and stabilize the shore.

 

Contour Wattling

Contour wattling is also suitable for areas with low and moderate levels of erosion. You just have to place a few bundles of stems and branches on the shoreline, and cover them with soil.

As a result, they will sprout and grow over a period of time and provide stability to the ground. It is a highly affordable technique of shoreline protection.

 

Brush Layering

Brush layering is typically suitable for badly eroded slopes. You can also use it along with geotextile installation to provide extra stability to the shoreline.

This process is quite simple as you just have to dig holes on the side of the slop and insert plant cuttings in it at a suitable angle so they can properly grow and stabilize the shore. 

 

The Bottom Line

By adopting the method discussed above, shorelines can be protected from erosion to a great extent.

The importance of geotextile and geotubes installation cannot be understated because such materials have proven to be highly effective in stabilizing the shorelines and maintain them in good conditions for a long period of time.
