1. introduction. beachdune systems are an important tourism resource for many coastal economies (klein et al., 2004).in recent decades recreational seashore activities have been concentrated mostly on sandy shores (caffyn and jobbins, 2003), with more than 70 of the world's beaches now experiencing erosion (e.g.: bird, 1996; sajinkumar et al., 2020; bitan et al., 2020; hasiotis et al., 2021).
