Coupling superposed 1D and 2D shallow-water models: Source terms in finite volume schemes [Article]
We study the superposition of 1D and 2D shallow-water equations with non-flat topographies, in the context of river-flood modeling. Since we superpose both models in the bi-dimensional areas, we focus on the definition of ...
Efficient numerical schemes for viscoplastic avalanches. Part 1: The 1D case. [Article]
This paper deals with the numerical resolution of a shallow water viscoplastic flow model. Viscoplastic materials are characterized by the existence of a yield stress: below a certain critical threshold in the imposed ...
