This manuscript reviews current methods, knowledge, and progress of numerical models for the marginal seas. Marginal seas cover areas that are larger than a coastal scale but smaller than a basin scale. It is a region where dynamics occurring in both scales interact, under the influence of detailed structures in bottom topography and coastlines, which often requires high spatial resolution models to resolve. Two aspects are raised, where numerical models of marginal seas could improve, straits exchange flows and river outflows. The dynamics of the straits exchange flows that occur between marginal seas and open ocean are first discussed, with a focus on the overturning circulation. The importance of resolving realistic western boundary currents is then discussed based on the framework of the island integral constraint. This framework becomes especially important when the straits that connect the marginal seas and open ocean are narrow. Lastly, a new approach for modeling river inflows and ocean circulation simultaneously is introduced. The use of a layer model is shown to successfully capture the water flow from land to the ocean during extreme precipitation events.
