Floating breakwaters (FBs) are distinguished as an environmentally friendly type of breakwater that are more deployed in the development of small ports. Dissipation and reflection are the main mechanisms by which FBs protect the leeward side; however, because of the structure geometry, a portion of the incident wave energy is transmitted to the shoreline. Thus, the transmission coefficient (Ct), which stands for the transmitted portion of wave energy in comparison with the total wave energy, is an important parameter that describes the structure's efficiency. Only a limited number of studies have been performed for the description of wave energy that is transmitted in the intermediate waters; therefore, in this study, an attempt has been made to present a proposed formula for the prediction of Ct in intermediate waters. The proposed formula is based on the experimental measurements performed in the current study. The proposed formula was also evaluated using extra data. The correlation coefficients of 0.75 and 0.69 for the data set of this study and extra data from previous studies revealed that the proposed formula is more accurate than the previous formula provided for shallow and intermediate waters.
