The beach profile and sediment transport are very important factors in the design of coastal structures, and the beach profile is mainly affected by a number of parameters, such as wave height and period, beach slope, and the material properties of the bed. In this study, considering wave height (H-0 = 6.5, 11.5, 16, 20, 23, 26 and 30 cm), wave period (T = 1.46 and 2.03 s), beach slope (m = 1/10 and 1/15) and mean sediment diameter (d(50) = 0.18, 0.26, 0.3 3 and 0.40 mm), an experimental investigation of coastal erosion profile (storm profile) was carried out in a wave flume using regular waves, and geometric characteristics of erosion profile were determined by the resultant erosion profile. Dimensional and non-dimensional equations were obtained by using linear and non-linear regression methods through the experimental data and were compared with previously developed equations in the literature. The results have shown that the experimental data fitted well to the proposed equations with respect to the previously developed equations. (c) 2007 Elsevier Ltd. All rights reserved.
