Global warming and Climate Deregulation has a direct impact on the hydraulic regime of rivers at the planetary scale. The example of the Rhône where the increase in hydroclimatic variability accentuates the torrentiality of the river, which is particularly worrying in a border area (France: Rhône Alpes; Switzerland: Canton of Vaud and Canton of Geneva), it results in:

• change in water flow velocity;
• change in the width of streams, streams, etc…
• the formation of new typologies linked to this growing volume of water.

Anticipation in the identification of these changes is a key issue on:

• the security plan (risk of flooding and flooding)
• the economic plan (release of secure surfaces for construction and public works)
• the ecological plan.

Therefore it is necessary to carry out the detection and mapping of future developments, from a consolidated and qualified way all along the river (Swiss side and French side), and for allow the reinforcement of the dikes.

The challenge of the “VRAIBioRStab” project is to couple on one side “the new
VR (Virtual Reality), AI (Artificial Intelligence), and 2D/3D Image Processing” technologies and on the other side the “physical models via real models”, and this, for the purpose of the study to identify the cases or can where “classic construction sites” of reinforcement of dikes can be replaced in a logic of circular economy by “biological sites” by “bio-mineralization”

Main 3D model Components :

• Hangar
• Tree
• Road
• Bridge
• Terrain
• Water

Component to extend model :

• Parasitic objects
• Realistic Physical materials properties
• Object to be handled: dikes; rocks; etc
• Real Time ergonomic interaction in immersive context

After producing the immersive realistic model – the innovative idea is to link it with the scaled 1/54e model. This connection based on IA technics allows the VR model to learn the Rhône behavior in this ZIS, and to correct the VR physical properties.

Finally we can insert in VR model different “Options of consolidation” and the idea is to prove that bio-mineralization option will be the best solution.
