“…In any case, other processes not included in the present work complicate the overall scheme here presented (i.e. the limitation and increasing scarcity of sediment inputs from the river, its intermittency, and the action of the NW winds, which generate currents that can redistribute part of the sediment input; Rodríguez-Santalla et al, 2021). These results must be carefully interpreted, and a deeper study focusing on external factors (i.e.…”

“…By applying remote sensing techniques, consistent and robust methodologies for sea-land mapping and coastline detection were recently obtained on a global scale [22,25,29,48,60,61]. However, heterogeneity of sea-land mapping and coastline delineation methods and the difficult access to these tools by coastal managers usually restricts their use [24,35,36,40,62,63]. The potential of GEE has already been demonstrated in previous studies [37,38,60,64,65], and we used S2 images within GEE in order to ensure accuracy and robust performance, as well as a user-friendly and accessible tool for coastal managers.…”

“…Furthermore, automatic sea-land mapping has many advantages over traditional methods. While manual shoreline delimitation is more accurate, it is labor-intensive and time-consuming [40], and, therefore, not the optimal option for high-frequency and long-term monitoring. However, as already demonstrated in previous studies, the use of indices for automatic sea-land mapping is biased towards false classification pixels due to clouds and breaking waves [41].…”

“…An integrated sea-land approach is needed to quantify coastal changes [39]. Some studies carried out this approach manually [40], which is more precise but time consuming and non-viable for monitoring tools, which need more automatic workflows [22]. Sea-land mapping is mostly used for coastline evolution studies, including erosion and accretion trends or sea-level rise [23,41,42], using image classification, image segmentation, and several indices.…”

Estuarine degradation is a major concern worldwide, and is rapidly increasing due to anthropogenic pressures. The Mediterranean Guadiaro estuary, located in San Roque (Cadiz, Spain), is an example of a highly modified estuary, showing severe negative effects of eutrophication episodes and beach erosion. The migration of its river mouth sand spit causes the closure of the estuary, resulting in serious water quality issues and flora and fauna mortality due to the lack of water renewal. With the aim of studying the Guadiaro estuary throughout a 4-year period (2017–2020), the Sentinel-2 A/B twin satellites of the Copernicus programme were used thanks to their 5-day and 10 m temporal and spatial resolution, respectively. Sea–land mapping was performed using the Normalized Difference Water Index (NDWI) in the Google Earth Engine (GEE) platform, selecting cloud-free Sentinel-2 Level 2A images and computing statistics. Results show a closure trend of the Guadiaro river mouth and no clear sand spit seasonal patterns. The study also reveals the potential of both Sentinel-2 and GEE for estuarine monitoring by means of an optimized processing workflow. This improvement will be useful for coastal management to ensure a continuous and detailed monitoring in the area, contributing to the development of early-warning tools, which can be helpful for supporting an ecosystem-based approach to coastal areas.

“…Since the end of the Second World War, many areas of the Mediterranean have been affected by a process of displacement of a large part of the population from inland to coastal areas [2,3], expanding many existing cities and building new ones, often substituting dune systems and coastal and river areas [4][5][6][7][8][9][10][11][12][13][14][15]. This strong anthropogenic pressure has caused the expansion of numerous existing ports and the construction of numerous new ports and has also modified not only the landscape but also the coastal dynamics, causing shoreline advancement on their updrift side and triggering shoreline erosion processes on their downdrift side, even at considerable distances from the ports [16][17][18][19][20][21][22][23][24][25][26][27]. These equilibrium conditions can also be altered by natural factors, the main ones being the wave climate and the balance between river and longshore sediment transport [28][29][30][31][32][33][34][35][36][37].…”

An important process that began in many Mediterranean countries in the last century, after the end of the Second World War, concerns the displacement of a large part of the population from inland to coastal areas, expanding many existing cities and building new ones. Following this expansion, some existing ports were expanded, and many new ports were built, mainly for commercial and tourist purposes. This strong anthropogenic pressure has modified not only the landscape but also the coastal dynamics, and significant shoreline erosion processes have often been observed, even at considerable distances from the ports. This paper analyzes shoreline changes due to the construction of ports in Calabria, based on geomorphological factors and wave forcings. Calabria is a region of Southern Italy, on the Mediterranean Sea, that is characterized by geomorphological, climatic, and anthropic peculiarities. In addition, other important effects caused by the construction of ports were also analyzed, such as shoreline advancement updrift, construction of coastal protection structures, siltation, and anthropogenic pressure. The main finding of this analysis is that coastal morphology plays a key role in the extent of shoreline changes due to the construction of ports. In fact, the greatest shoreline retreats were observed downdrifts of ports built in straight coastal areas. Furthermore, this analysis highlights that there is no direct correlation between wave climate and shoreline changes near the examined ports. The analysis described in this paper may be of interest both to the scientific field and to the planning and management of coastal areas. Furthermore, it is based on open-access data and was carried out using free software such as QGIS, so it is easily replicable and applicable in any coastal context.
