Rich structures

Rich structures are small-scale structures that provide habitat for organisms. There are different types of rich structures (see image below). Examples of rich structures are floating marshes (type 1), pontoon hulas (type 2) en pile hulas (type 3/4). Rich structures are relatively easy to apply and offer opportunities for added services even when physical conditions or design constraints require hard solutions and/or provide little space for Building with Nature. Application of rich structures increases the natural value of the area, dampens waves, reduces maintenance needs of quay walls and contributes to attractive landscapes.

How to use

A guideline for determining the feasibility and implementation of rich structures is presented below. In the pre-feasibility phase it is important to get insight in the physical boundary conditions and social-economic interests to determine the possibilities. In the feasibility phase the design is created in close collaboration between technicians and ecological experts.  Field trials can be used to improve the design for area specific conditions. After this, the design can be constructed and monitored. Costs depend on the design, construction implications, maintenance and operational cost and benefits.

Practical applications

On the right side, links are provided to different projects with rich structures. A short description of three projects where rich structures were applied is given below. In these projects different types (see image above) of rich structures were applied.
