Ecodesign & Biomimicry
</br>
for Coastal Ecological Engineering

Thanks to **eco-design** and **biomimicry** coupled with **coastal ecological engineering** and a systemic approach to coastal dynamics, we are developing new physical devices for **Integrated Shoreline Management** made of **bio-inspired unitary modules**, with the objective of providing solutions to **coastal communities** that need them. The latter are generally **constrained** by a strong **urbanization of their coasts** and a strong **exposure to the stakes** with no immediate possibility of strategic withdrawal. 


These innovative systems, the result of several years of research and development, are not opaque systems for fighting against nature (unlike dikes, groins, breakwaters and other riprap on the seafront), but ultra-porous systems, bio-inspired by the complex architecture of natural ecosystems, and transparent to hydro-sedimentary and ecological flows

Innovation

We are inspired by mangroves (mangrove roots), seagrass beds, rocky bottoms and corals to design unitary modules with hybrid and tortuous internal shapes that slow down wave speed and reduce swell energy from a storm level defined as destructive for beaches and ecosystems. These patented internal shapes are made of different three-dimensional meshes that can accommodate marine life within them in addition to their main hydrodynamic function.

Bio-inspiration

To manufacture our modules, we rely on different techniques such as the latest large-scale 3D printing technologies. They offer great morphological freedom while topologically optimizing the shape of the modules to minimize the amount of raw material and maximize their structural strength. 

3D Manufacturing

Thanks to the use of biogenic and biosourced materials and the control of some of their physico-chemical parameters, our modules are colonized in a few weeks to a few months by the first links of the submarine trophic chain (sessile species, ingenious species...) and are quickly transformed into a rich and diversified ecosystem serving as a habitat and nursery for local marine species, which may be of patrimonial or halieutic interest

Biocompatibility & Biofooling

Bio-inspired unitary module

Our **large scale** devices are made of **assembling our unit modules** on several linear meters. Their macroscopic shape can be **adapted** and **optimized** for the site of implementation. Life **colonizes** our solution in only **a few months** and participates in the **self-regulation of the device** thanks to **trophic mechanisms** coupled to **hydrodynamics generated** by the structure.

Thanks to their internal shape and custom assembly and anchoring mechanisms developed specifically for our modules, they fit together to form large-scale devices that adapt to immersion even in the most dynamic environments such as sandy bottoms. 

Assembly

We optimize the macroscopic shape and location of these multi-functional bio-inspired devices for sustained performance under any site energy conditions.

Optimization

Depending on the study site, we can adapt the macroscopic shape of our devices so that they are inspired by natural morphological forms that participate in the maintenance of coasts and the balance of ecosystems, such as sandbars, coral barriers or reef passes.

Multi-scale bio-inspiration

Once installed on the seafloor, these devices serve as large-scale habitats for marine life and as practice aids for wave-dependent activities and marine ecosystems such as surfing, diving, and snorkeling.
