abstract = {Beach behaviour and evolution are controlled by a large number of factors, being susceptible
to human-derived pressures and the impacts of climate change. In order to understand beach
behaviour at different scales, systematic monitoring programs that assess shoreline and volumetric
changes are required. Video-monitoring systems are widely used in this regard, as they are costeffective
and acquire data automatically and continuously, even in bad weather conditions. This
work presents a methodology to use the basic products of low-cost IP video cameras to identify
both the cross-shore and long-shore variability of tidal beaches. Shorelines were automatically
obtained, digital elevation models (DEMs) were generated and validated with real data, and the
outputs were combined to analyse beach behaviour from a morphodynamic perspective. The
proposed methodology was applied to La Victoria Beach (SW Spain) for the analysis of beach
variations over a 5-year period. The combination of shoreline position analysis and data from DEMs
facilitates understanding and provides a complete overview of beach behaviour, revealing alongshore
differences in an apparently homogeneous beach. Furthermore, the methods used allowed us to
inter-relate the different processes occurring on the beach, which is difficult to achieve with other
types of techniques.},
