Abstract:In this study, a new monitoring method was proposed based on the UAV LiDAR system, in conjunction with the coast dynamic changes and traditional monitoring modes.The basic principles and processes of the monitoring methods were analyzed and described, and we set the Ten-thousand-meters sandy beach in Haiyang as the research area to test them.For fulfilling the requirement of the monitoring method, we obtained the DEM data of the coastal zone and also verified the accuracies of the monitoring by the ground characteristic points and beach topographic profiles.The monitoring results indicate that (1) this method suits well for the coastal erosion monitoring over short-term window, and (2) it owns enough high accuracies for the monitoring of coastal dynamic variations.We anticipate that this method can be widely applied in coastal monitoring.
