Temporal variability in winter wave conditions and storminess in the northwest of Ireland
Winter storms have significant morphological impacts in coastal areas, often leading to extensive infrastructure damage and socioeconomic disruption. While storm-dominated coastal environments, such as the northwest coast of Ireland, are generally attuned to highly energetic wave conditions, morphol...
