abstract = {Predicting the response of rocky coasts to different erosional agents remains a great challenge at present. The episodic and
discontinuous nature of the instability processes typical of hard bedrocks makes it difficult to make predictions based on
observations over short research periods. This work aims to contribute to the understanding of the geomorphological evolution
of rocky cliffs by means of a case study of a geologically complex cliff (developed on quartzite and slate) located on
the Atlantic coast of Spain. The analysis of high-precision topographic models and orthophotographs, the use of geomatics
techniques and geomorphological characterization have made it possible to define a model of the cliff behaviour. The results
indicate that the structure of the bedrock determines the type of instability processes affecting the cliff and the morphology of
the associated deposits. Lithology is the other main conditioning factor: while slate is easily eroded, quartzite offers greater
strength and its detached blocks act as an effective natural defence element protecting the cliff and slowing down the coastal
retreat. The evolution model established for this cliff explains the absence of retreat in the study period (2003–2022) and
confirms the important role of local factors in cliff evolution.},
