•In this paper, we derive a new wave overtopping formula on reshaping berm breakwaters based on the assumption that the maximum wave momentum flux at the toe of the structure is proportional to the maximum wave run-up and the excess wave run-up overhead the crest of structure can lead to overtop the water over the structure.•A comparison is made between the predicted overtopping formula by the present study and formulae given by other researchers.•Recent approach method can provide an estimation technique that is at least as good as existing formulae by using a physical concept.
In this paper, a new wave overtopping formula on reshaping berm breakwaters is derived based on the assumption that the maximum wave momentum flux at the toe of the structure is proportional to the maximum wave run-up and the excess wave run-up overhead the crest of structure can lead to overtop the water over the structure. Wave momentum flux is a physically relevant descriptor of wave forcing having units of force. The first part of Lykke Andersen experimental data were selected randomly for which 80% were used to extend new formula to calculate wave overtopping in reshaping berm breakwaters and 20% were used to validate the generalization accuracy of the new formula as a second part of data. Finally, a comparison is made between predicted overtopping formula by the present study and formulae given by other researchers. The comparison shows that the overtopping predicted by the new formula has a good correlation with the experimental data compare to the other researchers and it can provide an estimation technique that is at least as good as existing formulae for the present experimental data.
