ABSTRACT

Because tidally induced residual currents are important in the long-term transport of materials and nutrients in the water column and in the exchange of waters between different basins, they have been modeled extensively in the last 15 years. This chapter summarizes the methods used in these models, and describes the computed residual currents in various coastal waters. It also summarizes the residual currents computed from the estuarine model, models for submarine banks and near straight coasts, two-dimensional depth-averaged tidal models, and two-level tidal model. The chapter aims to summarize the methods for modeling the tidally induced residual currents, and to describe the typical circulation patterns and their associated dynamics for the computed residual currents in various coastal waters. It discusses results of the narrow estuarine models and models for submarine banks and near straight coasts.
