Water flowing over soluble rocks can create patterns of multiple troughs bordered by sharp ridges. By combining field measurements, a numerical model and laboratory experiments, a team led by the MSC laboratory (CNRS/Université Paris Cité), in collaboration with the LPG (CNRS/Nantes Université/Université d'Angers) and the RDP (CNRS/ENS de Lyon/Inrae) has shown that the appearance of these shapes results from a geometric mechanism.

However, this principle is not sufficient to explain all the mechanical behaviors observed in reality. An international team has discovered that the macroscopic mechanical properties of gels are due to heterogeneities in their structure, inherited from the singular microstructure that the material adopts at the very moment of its gelation.
