## Abstract

The present study concentrates on the empirical formulas of Goda [1975, 2009]. The formulas were proposed for computing the transformation of three common representative wave heights (i.e. H_{1/3}, H_{max} and H_{m0}) on plane beaches. The objectives of the present study are to verify the Goda formulas for computing the transformation of H_{1/3}, H_{max} and H_{m0} on unbarred beaches and to extend the formulas for computing the transformation of H_{m}, H_{rms} and H_{1/10}. Laboratory data from small-scale and large-scale wave flumes with unbarred beach conditions are used to verify the formulas. The verification shows that the formulas give very good predictions of H_{1/3} and H_{m0}, but give fair prediction of H_{max}. The formulas are rewritten in the form of a general formula. The general form of Goda formulas is recalibrated and extended to compute other representative wave heights (i.e. H_{m}, H_{rms} and H_{1/10}). The general formula gives very good predictions of H_{m}, H_{rms}, H_{1/3}, H _{1/10}, H_{max} and H_{m0}.
