Wind-wave climate change and increasing erosion in the outer Río de la Plata, Argentina

The coastal area of Samborombón Bay ends in a short cliff which, during the last decades, has been undergoing an increased retrogression of approximately 8.2m decade -1. The aim of this paper is to investigate whether this accelerated erosion can be related to an apparent wind-wave climate change, w...
