Abstract
In practice, achieving a balance between accuracy, stability, and computational
efficiency in modeling contaminant dispersion in marine environments remains
challenging due to complex physical dynamics and numerical constraints. To
address these challenges, an enhanced cell-based model (CBM) is developed and
applied to simulate pollutant transport in the ocean. The CBM discretizes the
spatial domain into uniform cells, resulting in a naturally parallelizable
structure, and characterizes the transport process by incorporating both water
flow-driven convection and diffusion effects. Moreover, two approaches are
proposed for estimating the diffusion coefficient, and their performance is
compared to a first-order upwind scheme finite-difference method (FDM)
solution. Finally, the CBM is comprehensively compared with both the FDM and
the finite-element method (FEM) solvers under varying spatial and temporal
resolutions. Simulation results show that the CBM is less affected by the
Courant–Friedrichs–Lewy (CFL) conditions and demonstrates stable convergence
where the FDM fails or requires stricter settings. In addition, the CBM offers
a favorable trade-off between accuracy and computational efficiency under
coarse configurations. These results indicate that the CBM provides a reliable
foundation for dynamic modeling and integration with learning-based frameworks
in marine environment simulations.
