Hydraulic models include many uncertainties related to model parameters. Uncertainty Quantification (UQ) and Global Sensitivity Analysis (GSA) allow to quantify these uncertainties and identify the most influent parameters. To use traditional methods

International audience; In recent years, flooding hazard is usually assessed through numerical modelling. However, depending on the nature (e.g. 1D, 2D) and the breach characteristics (e.g. river geometry, bottom roughness, levees geometry) of the nu

Flood hazards in the inactive volcanic island of Tahiti are very high. Indeed, the island is located in the South Pacific Ocean, in humid tropical climate and is exposed to cyclones. Even if the island is small (1,042 km2 ), rainfalls and runoffs are
