International audienceIn this study, the modules TELEMAC-2D and SISYPHE of the Telemac-Mascaret Modelling System (TMS) have been used in combination with the OpenTURNS library (www.openturns.org) to perform an uncertainty quantification analysis of two-dimensional morphodynamic problems. Open-TURNS is a scientific library usable as a Python module dedicated to uncertainties treatment. A recently implemented API (Application Program Interface) allowed the communication between OpenTURNS and TELEMAC-2D/SISYPHE, and therefore the efficient implementation of Monte-Carlo like algorithms. In this problem, each uncertain sedimentological parameter, e.g. inlet mean diameter, Shields parameter, etc. has been associated to a statistical distribution , defined with OpenTURNS. A number of TELEMAC-2D/SISYPHE simulations has been proposed regarding the pre-defined random entries in order to guarantee the convergence of the Monte Carlo-like algorithms. This work allowed the implementation of uncertainty quan-tification analysis of computationally intensive morphodynamic simulations in the TMS. Thanks to the access to computer resources and optimized software, we were able to perform the uncertainty quantification analysis with a large set of variables, and therefore push the study further with the correlations effects analysis
