Abstract
In this work a numerical solution for the flow in a system of two basins connected by a channel is presented. The flow rate is assumed to be time dependent. With this assumption we intend to model the effect of tides in coastal systems. Our results show the formation of a vortex dipole at the channel outlet. Evolution of dipole depends strongly on the period of flow rate, as already noted by previous works. Using the velocity field obtained with the numerical method we calculate trajectories of fluid particles and show that dipole has an effect of suction in the region it pass. On the other hand the process of vortex formation and further evolution are well described.
