Title :

Flow-plants interactions, ecology and biomimetics : simple ideas on complex coupled systems.

Abstract :

There are many types and cases of mechanical interactions between plants and the flow that surrounds them. They range from wind induced motion in trees to the deformation of kelp under waves. Moreover, plant do grow differently when subjected to external stresses. I will try, through several examples, to show that the huge complexity of geometries, species, forces and configurations may be analysed with simple ideas. These will then be used to build some biomimetic applications.
