This study extends the analysis of Ianniello (1977) in deriving the two-dimensional (x-z) analytical solutions for the tidally induced residual currents in narrow sea level canals connecting two large adjoining bodies of water. The sea level canal is forced by tides from both open ends, and residual Eulerian and Lagrangian currents are induced in the canal by nonlinear interactions of the first-order tides. It was found that the residual currents are strongly influenced by the tidal amplitude and phase differences between the two open boundaries. Depending on the type of boundary tidal forcing, the residual Eulerian velocity ⟨u2⟩ may flow in either direction and produce two-layer structures in the vertical. The Stokes velocity ⟨us⟩ may work either in concert or in opposition with ⟨u2⟩, so the residual Lagrangian velocity ⟨ulag⟩ may be greater than ⟨u2⟩. Given a particular set of boundary forcing conditions, the depth-averaged residual Lagrangian velocity ⟨ulag⟩d is a nonzero constant, so residual mass transport between the adjoining water bodies through the canal is permitted. The most effective way of producing vigorous residual currents through the canl is for the tidal forcing at one open boundary to have a higher amplitude and a phase lead relative to the tidal forcing from the opposite end. ¿ American Geophysical Union 1989
