Conduits Karstiques en 3D: une méthode de simulation stochastique

Abstract : Karstic systems play an essential role in fluid flows. Modelling the morphology of their conduits can help to better appraise those systems, their volumes and thus their relationships with fluids. The stochastic simulation method presented in this contribution uses the information brought by the local geological context (faults, inception horizons…) to generate karstic conduits with shapes reminiscent of morphologies observed in situ (lenses, keyhole…). This methodology is based on a front propagation method to generate a pseudo-distance field constrained by the geology. That field is then truncated using a random threshold, giving a possible representation of the conduit from the available data.
