Abstract: Based on the collected remote sensing and wave measurement data, this study investigated the interannual and seasonal evolution of the Boao tidal inlet, Hainan Province. The annual and seasonal longshore sediment transport was calculated based on CERC formula. The results show that on the time scale of inter-annually, the inlet throat is subject to a shrink due to the propagation of sand spits on its southern and northern sides. This decrease of inlet throat is interrupted by storm river discharge brought by typhoons during the wet season in the region. Based on the sand mass conservative law, the longshore sediment transport is inversely estimated. The magnitude of thus obtained sediment transport is similar to that based on CERC formula, although some discrepancy exists, which indicates the formula is adapted to Boao.
