| Research Abstract |
Measuring devices that are fixed to definite points are employed in the usual surf zone observations, which provide accurate time records of hydrodynamic items. The deployment of the instruments, however, is limited in most field experiments, which restricts the spatial understanding of the surf zone dynamics. In this context, a moored video system is developed to obtain spatial images of the surf zone. Field experiments were conducted at HORS, a research pier located in Hazaki, Japan. Results of the video record processing demonstrated the potential of the system showing that the system is able to capture the unsteady and spatial features of the surf zone hydrodynamics.
