Short summary
A narrow tidal strait often leads to net transport in one direction, and the water flowing through the strait is not the same as the water that is drawn back into the strait when the tidal flow turns. We investigated this process by simulating the transport through tidal straits of different lengths and widths. A simple theory is established that describes the net transport. The theory can be applied to real coastlines when predicting spreading of pollution and other substances in the ocean.
