Web6 de abr. de 2024 · Additionally, these techniques can be used as reduced order models (ROMs), which allows the reduction of high-order models to a lower-dimensional representation. These ROMs can still capture the essential physics of the flow while being computationally efficient. Webare, for the ﬁrst time, simulated with a high-order spectral, boundary perturbation scheme. The paper is organized as follows: In section 2, we present the mathematical static and moving bottom topography. In section 3, we give a description of the numerical methods for discretization of the equations of motion and for wave genera-
