Abstract
Remote video imagery using shoreline edge detection is widely used in coastal monitoring in order to acquire measurements of nearshore and swash processes. Some of these systems have very limited flexibility due to their rigid structures and require considerable investment in hardware. As such, there is a need for an autonomous low-cost system that can be rapidly deployed in the field, while still producing the outcomes required for coastal monitoring. This research presents a sensitivity analysis of time-lapse intervals for two low-cost time-lapse cameras located in a remote coastal area, overlooking a dissipative beach-dune system. Surveyed beach profiles were used to assess changes in beach elevation from December 2021 to February 2022, and a coupled wave-morphology model was developed using SWAN and XBeach to simulate the observed changes.References
