ESTIMATING CHANGES IN GRAVEL BEACH SLOPE USING A VIDEO MONITORING SYSTEM - A CASE STUDY OF THE PLOČE BEACH IN RIJEKA, CROATIA

Beach slope is of critical importance for coastal area protection, as well as for other coastal morphodynamic research. Despite its importance, a reliable method for estimating slope is still not defined. In this paper, a new efficient method using VMS technology is presented. The beach slope is calculated by dividing the difference in the tide level with the shoreline distance along a cross-shore transect at different times. The result of calculation using this technique shows good agreement with other methods and demonstrates the potential of VMS for effective beach slope monitoring.
