A staggered semi-implicit spectral discontinuous Galerkin scheme for the shallow water equations

► Semi-implicit DG scheme for the shallow water equations on staggered meshes. ► Large time steps, efficient for steady or low Froude number flows. ► Block-penta-diagonal system for only one scalar unknown (free surface). ► Quadrature-free method using precomputed universal matrices and tensors. ► S...
