“Improvement of the Plantation Success in a Crib Wall in a Mediterranean Hydro-Meteorological Risks Scenario—Practical Results”

The use of fiber rolls or HDCL (high-density coir logs) in crib walls and the effect on the growth of planted shrub, the development of roots, the colonisation of native vegetation and, ultimately, the structure’s resistance to floods.

Guide for the design and construction of crib walls

In recent years, we have verified the existence of crib walls works that omit basic aspects for the success of these structures. The lack of preparation of the staff designing and executing the works leads to serious mistakes such as the foundation, the maximum permissible height, the structure, and the role of the plant. Some of them have collapsed, compromising the credibility of the technique.
This document provides a clear guideline to have better knowledge on the design and construction of new Nature-Based Solutions (NBS). Naturalea has written this document within the framework of the OPERANDUM project to create a base for the use of crib walls, a soil bioengineering technique which is a useful alternative to face hydrometeorological hazards instead of classical solutions.
In the case of construction, we recommend practical training in specific courses such as those organised by the European Federation of Soil Bioengineering (EFIB).

Root system assessment of helophytes · Resistance and root growth capacity in vegetated fiber rolls

Good resistance of the vegetated rolls is verified from the extrapolation of data from wild media, in which speeds of 4.18 m/s were reached successfully.
The resistance of the works where vegetated rolls have been used depends more on the quality of the execution than on the natural impacts.
