Morphodynamic Evolution and Adaptability of Nourished Beaches

ABSTRACT Liu, G.; Cai, F.; Qi, H.; Zhu, J., and Liu, J., 0000. Morphodynamic evolution and adaptability of nourished beaches. Beach nourishment has been widely used for coastal protection in China. However, few beaches have been monitored after nourishment, and the evolution of nourished beaches has not yet been elucidated. This paper presents a study of two nourished beaches, both of which are in low–wave-energy environments but have different tidal ranges: Huizhan Beach, with a large tidal range, and Meiliwan Beach, with a small tidal range. To gain a better understanding of the evolution of these nourished beaches, beach profile surveys were carried out repeatedly over 4 and 2 years after nourishment, respectively. The nourished beach evolutions were analyzed in terms of profile morphology, foreshore slope, dry beach width, and remaining sand volume. From the results obtained, it can be seen that Huizhan Beach profiles demonstrated major changes during the initial adjustment, followed by a stable state...
