Wave Run-Up Monitoring on Rubble-Mound Breakwaters Using a Photogrammetric Methodology
Publication: Journal of Performance of Constructed Facilities
Volume 30, Issue 4
Abstract
Wave overtopping in rubble-mound breakwaters is an aspect that must be controlled in order to ensure the correct operation of port facilities. This manuscript shows a photogrammetric methodology to automatically monitor this process based on the use of low-cost cameras. Cameras are used for acquiring video of breakwaters. Then, image processing algorithms based on binarization tresholding and projective transformation, combined with geometric data of the structure provided by the facility manager, are used to evaluate the run-up height and automatically detect the existence or absence of a overtopping event. The methodology was successfully tested in the outer port of Punta Langosteira, A Coruña, Spain.
