| 摘 要： | A high-frequency, high-resolution shore-based video monitoring system(VMS) was installed on a macrotidal(tidal amplitude >4 m) beach with multiple cusps along the Quanzhou coast, China. Herein, we propose a video imagery-based method that is coupled with waterline and water level observations to reconstruct the terrain of the intertidal zone over one tidal cycle. Furthermore, the beach cusp system(BCS) was precisely processed and embedded into the digital elevation model(DEM) to more effectiv...
