Meanwhile, field data such as wave climate and topographic changes along the coasts between Chiayi and Tainan County are collected as the proof of the models. 　　Results also reveal that, after the construction of Pu-Dai harbor, oblique waves move along both north and south breakwaters of the harbor, which also make nearshore currents move shoreward along the breakwaters. The expanding of coastal structures blocking longshore sediment transport may lead to the jetty effect.
