In order to understand beachbehaviour at different scales, systematic monitoring programs that assess shoreline and volumetricchanges are required. Video-monitoring systems are widely used in this regard, as they are costeffectiveand acquire data automatically and continuously, even in bad weather conditions. Thiswork presents a methodology to use the basic products of low-cost IP video cameras to identifyboth the cross-shore and long-shore variability of tidal beaches. Shorelines were automaticallyobtained, digital elevation models (DEMs) were generated and validated with real data, and theoutputs were combined to analyse beach behaviour from a morphodynamic perspective. Theproposed methodology was applied to La Victoria Beach (SW Spain) for the analysis of beachvariations over a 5-year period. The combination of shoreline position analysis and data from DEMsfacilitates understanding and provides a complete overview of beach behaviour, revealing alongshoredifferences in an apparently homogeneous beach. Furthermore, the methods used allowed us tointer-relate the different processes occurring on the beach, which is difficult to achieve with othertypes of techniques.
