Abstract
Foredunes provide habitat and natural protection in coastal areas. The dune formation and development are controlled by aeolian, marine, and ecological processes (Hesp, 2002; Houser, 2009). The dune height is a key parameter for determining storm impact on barrier islands (Sallenger, 2000) and for calculating the Coastal Resilience Index (Dong et al., 2018). Therefore, the understanding of the relative role of both aeolian and marine processes on controlling dune evolution are fundamental for coastal hazards assessment on the context of climate change. A previous study (Cohn et al., 2018) conducted on a meso-tidal beach suggested that extreme water level can contribute to dune growth. The purpose of the present study is to investigate the role of aeolian and marine processes on the dune growth at a low-energy sea-breeze dominated micro-tidal beach located in northern Yucatan peninsula by means of high-resolution beach surveys.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/6f7pM01_jho

Beach profiles have been conducted from May, 2015 to March, 2020 on a weekly and bi-weekly basis using an RTK GPS system (Fig. 1c)
A fixed reference station is located in the roof of the coastal laboratory located near the port
