“…Tendências similares são observadas em outras praias do mundo, sendo, em geral, agravadas pela influência antrópica. No Kuwait, foram registradas taxas erosivas de 9,73 m/ano e de acreção de 10,88 m/ano, sendo que os processos erosivos ocorreram em áreas que passaram por mudanças em sua morfologia (engordamento de praia) (Aladwani, 2022). Na costa de Tetouan, no Marrocos, a área que se encontra sob erosão é resultados de efeitos cumulativos de processos naturais e atividades antropogênicas (Benkhattab et al, 2020).…”

“…Landsat e Copernicus Sentinel), têm sido cada vez mais publicados (Benkhattab et al, 2020;McAllister et al, 2022;Nguyen Hao & Takewaka, 2022;Spinosa et al, 2021). Além de permitir a análise pretérita do comportamento morfológico das áreas costeiras, esses resultados podem auxiliar na elaboração de modelos de previsão da linha de costa futura (Aladwani, 2022;Barik et al, 2021).…”

O comportamento da linha de costa é um indicativo das tendências à que o sistema costeiro está submetido, pois é a interface de contato da transição continente-oceano. Neste sentido, a Restinga da Marambaia e os arcos praiais Macumba/Recreio-Barra da Tijuca (SE do Brasil) foram avaliados quanto à resposta da linha de costa às forçantes meteo-oceanográficas nas escalas temporais de longo e médio prazo, bem como foram mapeados seus graus de vulnerabilidade. Na escala de longo prazo (1986-2018), foram utilizadas imagens de satélite Landsat, dados de reanálise de ondas do modelo WaveWatch3, registros meteorológicos e medições do nível médio do mar. Na escala de médio prazo (2016-2018), foram levantados onze perfis topográficos, com coleta de amostras de sedimentos, nas praias Macumba/Recreio-Barra, além da análise dos registros de boias oceanográficas em águas profundas e rasas. Por fim, estas informações permitiram elaborar um Índice de Vulnerabilidade Costeira à erosão e inundação. De modo geral, 18% da linha de costa encontra-se sob erosão, 52% encontra-se estável e 30% está avançando. No período analisado, foram contabilizados cerca de 400 eventos de tempestade, que durante os anos de La Niña foram mais energéticos e culminaram em uma erosão mais severa. O nível do mar na região apresenta tendência de aumento (1,93 mm/ano). O reflexo destes resultados, somado aos graus de ocupação urbana nas praias estudadas, exibem baixa vulnerabilidade no setor oeste da Marambaia, enquanto que os setores central e extremo leste configuram-se como altamente vulneráveis. Na Macumba o setor oeste exibe baixa vulnerabilidade, em contraste com o setor leste que é muito vulnerável. No arco Recreio-Barra nota-se o aumento da vulnerabilidade de oeste para leste. Estes resultados indicam que a influência antrópica tem um papel importante em áreas que são naturalmente propensas à alta vulnerabilidade, exigindo uma maior compreensão das condições naturais associadas às intervenções antrópicas.

“…The erosion rate was recorded as 10.01 m/year while the accretion rate reached 10.2 m/year. Aladwani [94] investigated the shoreline dynamics in Kuwait between 1986 and 2021 using DSAS, EPR, and LRR. The study found that erosion is the main pattern that affects the shoreline change, and this process was due to natural causes.…”

This research aims to examine changes in the eastern part of Qatar’s shoreline from 1982 to 2018 by means of satellite imagery. Five different time periods, namely 1982, 1992, 2002, 2013, and 2018, were analysed to determine shoreline movements and shoreline variations. Techniques such as maximum likelihood classification, the normalised difference vegetation index, and tasselled cap transformation were utilised to extract the shoreline data. Linear regression rate statistics were used to quantify the rate of shoreline variations. The results indicate that the majority of shoreline accretion is a result of human activities such as coastal construction, land reclamation, and building artificial islands, which are associated with the high economic activity over the past two decades. Significant changes were observed in Lusail City, The Pearl, and Hamad International Airport (HIA). Natural sediment accumulation was also observed in Al Wakra and on the southern side of HIA. In general, there were more land gains than losses throughout the study period, and the shoreline increased by twice its previous length. The field survey confirmed the presence of sandy and rocky beaches, as well as a shoreline with protective structures such as natural limestone rocks and concrete reinforcement.

“…However, in recent times, the extensive man‐made modifications of coasts and lands, that is, ports, coastal defence structures and human settlements, become key factors in triggering coastal dynamic changes (Chu et al, 2020; Di Stefano et al, 2013; Fletcher et al, 2012). As such, many studies on shoreline changes throughout the world have been carried out over the last few years (Aladwani, 2022; Bacino et al, 2020; Borzì et al, 2021; Quang, Linh et al, 2021). Shoreline change analysis methods that have been applied worldwide comprise the use of video images introduced by Holman et al (1993), Plant and Holman (1997) and Lippmann and Holman (1989), numerical modelling by applying continuity equation in LITPACK software (Rezaee et al, 2019), and computation of End Point Rate (EPR), Linear Regression Rate (LRR) and Weighted Linear Regression Rate (WLR) statistical parameters from image analysis utilizing Digital Shoreline Analysis System (DSAS) software (Johnston et al, 2023; Laksono, Borzì et al, 2022; Santos et al, 2021).…”

The coastal region of Augusta, eastern Sicily, Italy, is a densely populated zone, where human pressures profoundly shaped the coastal and land dynamics. So far, understanding the interaction between natural and human processes in modelling coastal geomorphology is still quite challenging. However, coastal and environmental monitoring poses the bases for managing coastal areas properly. Therefore, the aim of this research was first to understand the medium‐term shoreline changes along Augusta Bay between 1972 and 2021, and then assess the main local coastal modifications determined by the increasing coastal armouring. To do so, the shorelines dataset was extracted from Landsat and Sentinel‐2 satellite imageries using the NDWI and mNDWI methods and then statistical parameters were computed using Digital Shoreline Analysis System (DSAS). Results show that this coastal fringe experienced significant shoreline recession over the studied time interval. Negative shoreline shifts are higher in correspondence with torrent deltas, as a result of the increasing human and natural forces insisting on the land and coastal environments. Since 1970s, Augusta Bay registered a significant increase in artificial coastal length and a coastal armouring index of Maximal level was reached today.
