Soil bioengineering applied to restoration of rivers
Soil and water bioengineering applied to restoration of rivers and river banks consists of the use of living plants along with other natural materials (wood, rocks, blankets and organic meshes, etc.) and other synthetic materials (geotextiles, meshes, geonets, etc.). All this while incorporating and taking advantage of local elements (land, topography, microclimate, etc.) to achieve structural, ecological and geomorphological objectives in a river restoration project.
Therefore, it is not a matter of producing more or less massive plantations on river banks, many of which end up disappearing.
Soil bioengineering requires extensive prior studies on the ecosystem and river dynamics so that the plants are placed where they should be and in the correct way, while ensuring their survival and development.
These techniques can also contribute to structural goals, replacing other techniques used until now in pipelines and protection works, such as breakwaters, and concrete on many occasions. The latter can destroy the fluvial dynamics and have a strong impact on aquatic ecosystems, banks and landscape.
Soil and water bioengineering techniques are increasingly known and used in Spain. They are also well-developed in other European countries such as the United Kingdom, Germany, Italy and Sweden. It is expected that they will be used more and more frequently, replacing the current piping projects based on breakwaters and concrete.
At Naturalea, we have been clearly committed to the future development of these techniques for a long time now, and we offer an opportunity to incorporate this new way of understanding into the restoration and improvement of our rivers.
