文摘
- •
1D Multiwavelets Discontinuous Galerkin Adaptive Shallow Water model is assessed.
- •
The effect two RKDG2 schemes in the adaptive context is studied.
- •
Multiresolution runs are based on a 2-cell coarse mesh allowing 8 resolution levels.
- •
Significant reduction of computational cost is achieved by the adaptive scheme.
- •
Traits inherent to the numerical solution are conserved across resolution levels.
