Rich revetments 

Enriching revetments comprises designing and optimizing revetments in a way that they become more suitable as habitat for different flora and fauna species. Examples are the use of rough rubble instead of smooth concrete and the construction of tidal pools. Both provide additional habitat and/or shelter for algae, polyps, sponges, crabs and juvenile fish. Enriching revetments does not only increase the natural value of revetments, but also offers opportunities for education and raising awareness among designers, constructors, students and visitors. This concept is relatively easy to apply, does not require much (additional) space and can provide added services even when physical conditions or design constraints require hard solutions.

How to Use


Guidence is presented below to determine the feasibility and design for enriched revetments. As a first step of the design process an analysis of the planned works and its bordering ecosystem is needed. Based on conceptual design principles a technical design can be realized and budgeted.

Practical Applications


A number of different field cases are presented on the right side, providing applications of the concept of Rich Revetment. Design or application can greatly differ among sites, depending on goals (coastal protection, nature development, retention) and specific local conditions. For example, depth and wave exposure determine what design is best applicable. Rich revetment structures are typically applied in shallow environments with limited wave exposure. Experiences from specific cases can be used as inspiration for future designs. For more information on the Building with Nature cases we refer to the case description pages.
