A third-order finite volume semi-implicit method for the Shallow Water-Exner model
Enrique D. Fernandez-Nieto, Jose Garres-Diaz, Emanuele Macca +1
In this work, third-order semi-implicit schemes on staggered meshes for the shallow water and Saint-Venant-Exner systems are presented. They are based on a third-order extension of…

An almost fail-safe a-posteriori limited high-order CAT scheme
E. Macca, R. Loubere, C. Pares +1
In this paper we blend the high order Compact Approximate Taylor (CAT) numerical schemes with an a-posteriori Multi-dimensional Optimal Order Detection (MOOD) paradigm to solve hyp…
