A steady state, frictional model of a two-port, unbounded, ocean basin is formulated. The ocean is considered homogeneous and incompressible. The non-linear field accelerations and the horizontal exchange of momentum are neglected. The flow is driven by specifying the flow through the two ports and is retarded by bottom friction. The equations of motion are set up and are solved by using Fourier integrals. Numerical methods are used to evaluate the resulting integral. Results of six cases using four different values of the bottom friction coefficient and three different port widths are presented. In the case where the bottom friction coefficient is low, the current loops far to the west. As the coefficient increases, the current approaches Laplacian flow. The variation in port width essentially affects the overall scale but not the characteristic shape of the flow. Author
