heal.abstract In this paper experimental data on wave induced harbour basin oxygenation through rubble mound breakwater structures are presented. Experiments with permeable and impermeable structures were performed. It is shown that significant harbour basin oxygenation is the result of horizontal transport through the permeable structure. The data was analyzed with a two-cell model for dissolved oxygen prediction near a rubble mound breakwater structure. In the model the oxygen transfer through the air-water interface is considered a source term in the transport equation and the exchange through the structure is also taken into account. The mass transport equations for both sides of the structure are solved analytically and expressions for the time evolution of D.O. concentration for the seaward and harbour sides are derived. The solutions depend on the initial conditions, the oxygen transfer coefficient and the exchange flow rate. It is also shown that the segmentation of the air water oxygen flux into increase of dissolved oxygen concentration of the seaward side and horizontal transport towards the harbour side tends to a constant value, independent of the initial conditions. en
