This paper proposes a multiscale modeling approach for paralic confinement in coastal environments, emphasizing the significance of interface length between interconnected areas for numerical simulations.

Contribution

It introduces a method to split the confinement problem into subproblems for each area, facilitating modeling of interlocked coastal regions.

Findings

Splitting the confinement problem improves modeling flexibility.

Interface length significantly impacts confinement behavior.

Multiscale approach enhances numerical simulation accuracy.

Abstract

This paper is in the continuity of a work program. Its goal is to develop an approach of the paralic confinement usable from the modeling slant, before implementing it in numerical tools. More specifically, we here deal with the multiscale aspect of the confinement. If a paralic environment is separated into two (or more) connected areas, we will show that is possible to split the confinement problem into two related problems, one for each area. At the end of this paper, we will focus on the importance of the interface length between the two subdomains.
