Note
A two-dimensional, four-layer numerical model of tidally induced residual flow is used to quantify longitudinal transport through the interior of Indian River lagoon, on Florida's Atlantic coast. Water depths and surface slopes at the approximate midpoint between two inlets are calculated by assuming that the tide in the interior of the lagoon is the superposition of exponentially damped sine waves representing six tidal constituents. Tidal waves moving south from one inlet are modified significantly by the same six constituents moving north from a second inlet.
