“…Information on the long-term spatial and temporal dynamics of coastal inlets would enable researchers to further advance the existing knowledge on the mechanics and drivers of inlet opening/closure (e.g., Behrens et al, 2013;Bertin and Mendes, 2019;González-Villanueva et al, 2017;Mcsweeney et al, 2018;Mcsweeney and Stout, 2020;Morris and Turner, 2010;Ranasinghe and Pattiaratchi, 2003;Slinger, 2017;van Ormondt et al, 2020;Velasquez Montoya et al, 2018), the hydrology (e.g., Gale et al, 2007) and ecology (e.g., Gladstone et al, 2006;Scanes et al, 2020) of intermittent estuaries, or the impacts of climate change on coastal inlet dynamics (e.g., Duong et al, 2016;Duong et al, 2017Duong et al, , 2018. To date, however, the potential of satellite remote sensing remains poorly explored and there is need for an automated and transferable method to monitor intermittent coastal inlets worldwide.…”
