en مقاله پژوهشي Research Paper A reshaping berm breakwater is a type of rubble mound breakwater in which, its seaward slope is allowed to reshape under wave attacks. There are some key parameters in the reshaped seaward profiles, which can schematize the reshaped profile of a berm breakwater. A total of 412 test results was used directly to cover the impact of sea state conditions and structural parameters on these reshaping parameters. In this study, the key parameters are derived using the M5' model trees. According to these new reshaping parameters, a computer program is written in MATLAB to predict the reshaped profile of a berm breakwater. The performance of the new program is compared with BREAKWAT software in the range of variation of the experimental data.
