Abstract : The equations for tidal flow through inlets into bays have been studied by many investigators. Perhaps the best known is the one by Keulegan in 1951. He considered nonlinear friction but assumed no inertia in the inlet, no river discharge, constant inlet cross-section and bay surface area over a tidal cycle, and uniform bay elevation. This study analyzes these assumptions in four models; an inertia model, a river discharge model, a changing area model and a shallow water wave model; and predicts their effects. The results are presented in graphical and equation form. They are then compared to real inlets and the limitations of each model are discussed. (Author)
