“…The tidal motion can cause calculation errors as the position of the land-water boundary is affected. Rates for 1951-2013 as reported by Sinitsyn et al (2020) are lower with 1.8 m/years. Rates seem to have increased at Varandai as well.…”

“…On average the erosion rate on Arctic coasts is 0.5 m/year, but in the Laptev East Siberian and the US and Canadian Beaufort Seas the rates are much higher (3 m/year and more) (Lantuit et al, 2012, see also Figure 1). The Barents Sea coast also includes low-gradient sandy shores with comparably high erosion rates (2-5 m/yr, Sinitsyn et al, 2020).…”

The applicability of optical satellite data to quantify coastal erosion across the Arctic is limited due to frequent cloud cover. Synthetic Aperture Radar (SAR) may provide an alternative. The interpretation of SAR data for coastal erosion monitoring in Arctic regions is, however, challenging due to issues of viewing geometry, ambiguities in scattering behavior and inconsistencies in acquisition strategies. In order to assess SAR applicability, we have investigated data acquired at three different wavelengths (X-, C-, L-band; TerraSAR-X, Sentinel-1, ALOS PALSAR 1/2). In a first step we developed a pre-processing workflow which considers viewing geometry issues (shoreline orientation, incidence angle relationships with respect to different landcover types). We distinguish between areas with foreshortening along cliffs facing the sensor, radar shadow along cliffs facing away and traditional land-water boundary discrimination. Results are compared to retrievals from Landsat trends. Four regions which feature high erosion rates have been selected. All three wavelengths have been investigated for Kay Point (Canadian Beaufort Sea Coast). C-and L-band have been studied at all sites, including also Herschel Island (Canadian Beaufort Sea Coast), Varandai (Barents Sea Coast, Russia), and Bykovsky Peninsula (Laptev Sea coast, Russia). Erosion rates have been derived for a 1-year period (2017-2018) and in case of L-band also over 11 years (2007-2018). Results indicate applicability of all wavelengths, but acquisitions need to be selected with care to deal with potential ambiguities in scattering behavior. Furthermore, incidence angle dependencies need to be considered for discrimination of the land-water boundary in case of Land C-band. However, L-band has the lowest sensitivity to wave action and relevant future missions are expected to be of value for coastal erosion monitoring. The utilization of trends derived from Landsat is also promising for efficient long-term trend retrieval. The high spatial resolution of TerraSAR-X staring spot light mode (< 1 m) also allows the use of radar shadow for cliff-top monitoring in all seasons. Derived retreat rates agree with rates available from other data sources, but the applicability for automatic retrieval is partially limited. The derived rates suggest an increase of erosion at all four sites in recent years, but uncertainties are also high.

“…The deposition of sediments produced by the sea on the coast, together with the contribution of sediments from rivers, beaches or cliffs, are the cause of the formation of coastal deposition landforms (Nagle 2000), whereas the intense high energy surge results in the formation from coastal erosion landforms (Earle 2015). According to Sinitsyn et al (2020), "wave action defines long-and cross-shore sediment transport, which in turn results in erosion or deposition at a given location".…”

This research article refers to the coastal region around Santa Marta (Colombia), showing a valuable geodiversity from a coastal geomorphology point of view, with great scientific importance for the study of coastal landscapes and attractive for the development of geotourism. The landscape value of the coastal regions of the Colombian Caribbean, in particular of the coastal region around Santa Marta, should be globally recognized to improve and protect its aesthetic and environmental value through geoeducation and geotourism activities that contribute to its geoconservation, motivating efficient management that outlines guidelines that promote the development of appropriate tourist infrastructure, centers of scientific interpretation, dissemination and educational materials, active exchange with geoparks, continuous improvement, and participation of local communities.

<p><em>On the one hand, the coastal area promises abundant natural resources, but on the other hand, there are potential threats of disaster for the people living in that area. Coastal erosion or abrasion is a threat/danger that harmful to communities in coastal areas in Indonesia. One of the areas affected by abrasion in Indonesia is Rembang Regency. This study attempted to analyze the physical and social impacts of abrasion in the Rembang Regency. This study was conducted qualitatively by utilizing Ikonos High-Resolution Satellite Imagery, field surveys, and interviews as the basis for the analysis of the impact of the abrasion disaster. Respondents in this study were communities and government officials in areas affected by abrasion which were determined by purposive sampling technique. The results of the data analysis show that the physical impacts of abrasion are classified into four categories, namely heavy damage, moderate damage, minor damage, and no damage, while the social impacts are in the form of psychological, sociological, and economic disturbances which have implications for decreasing welfare. Therefore, an in-depth analysis is needed to determine the abrasion disaster management policy in Rembang Regency.</em></p>
