“…For example, some researchers have found a relationship between increased shoreline erosion in areas around the mouths of dammed rivers and in areas with high population densities in the Gulf of California [13]. Research conducted on the East Coast of South Korea found that the artificial structures constructed along the coast have not completely solved or stopped erosion but shifted it from one location to another [14]. On the contrary, work by Skilodimou et al [15] shows how coastlines have been enhanced by 40% over the last 76 years due to human interventions, in this case, earth filling.…”

A good understanding of historical change rates is a key requirement for effective coastal zone management and reliable predictions of shoreline evolution. Historical shoreline erosion for the coast of Guardamar del Segura (Alicante, Spain) is analyzed based on aerial photographs dating from 1930 to 2022 using the Digital Shoreline Analysis System (DSAS). This area is of special interest because the construction of a breakwater in the 1990s, which channels the mouth of the Segura River, has caused a change in coastal behavior. The prediction of future shorelines is conducted up to the year 2040 using two models based on data analysis techniques: the extrapolation of historical data (including the uncertainty of the historical measurements) and the Bruun-type model (considering the effect of sea level rises). The extrapolation of the natural erosion of the area up to 1989 is also compared with the reality, already affected by anthropic actions, in the years 2005 and 2022. The construction of the breakwater has accelerated the erosion along the coast downstream of this infrastructure by about 260%, endangering several houses that are located on the beach itself. The estimation models predict transects with erosions ranging from centimeters (±70 cm) to tens of meters (±30 m). However, both models are often overlapping, which gives a band where the shoreline may be thought to be in the future. The extrapolation of erosion up to 1989, and its subsequent comparison, shows that in most of the study areas, anthropic actions have increased erosion, reaching values of more than 35 m of shoreline loss. The effect of anthropic actions on the coast is also analyzed on the housing on the beach of Babilonia, which has lost around 17% of its built-up area in 40 years. This work demonstrates the importance of historical analysis and predictions before making any significant changes in coastal areas to develop sustainable plans for coastal area management.

“…SLR merupakan salah satu fenomena yang disebabkan adanya pemanasan global dan berpengaruh pada perubahan iklim sehingga menyebabkan perubahan secara cepat di kawasan pesisir yang salah satunya berdampak pada ekosistem, degradasi lahan, dan garis pantai (Ankrah et al, 2022;Halder et al, 2022;Nijamir et al, 2023) Garis pantai didefinisikan sebagai batas antara lautan dan daratan yang dipengaruhi oleh gelombang pasang surut dan digunakan sebagai parameter utama pengamatan perubahan lingkungan kawasan pesisir. Garis pantai merupakan salah satu fitur geomorfologi dinamis yang selalu berubah yang disebabkan proses alamiah, kondisi iklim dan faktor antropogenik seperti peningkatan aktivitas manusia dalam hal konstruksi pantai, pembangunan jetty, serta pengembangan kawasan wisata (Halder et al, 2022;Dewi RS et al, 2020;Yum et al, 2023;Hossen et al, 2023). Perubahan garis pantai merupakan salah satu isu besar dalam pengelolaan kawasan pesisir, untuk itu diperlukan pengawasan secara berkala agar dapat memahami dinamika dan distribusi spasial perubahan di kawasan pesisir dalam rangka perencanaan pencegahan bencana (Halder et al, 2022;Mishra et al, 2020;Al-Zubieri et al, 2020).…”

Garis pantai adalah fitur geomorfologi yang sangat dinamis dan rentan mengalami perubahan yang disebabkan oleh fenomena alam ataupun aktivitas manusia. Perubahan garis pantai akan berdampak pada pengelolaan kawasan pesisir dan mengancam kelangsungan sumber daya pesisir. Pengamatan perubahan garis pantai dapat dilakukan menggunakan analisis perhitungan statistik dengan variabel statistik maupun variabel fisik. Tulisan ini bertujuan untuk melakukan review dan membandingkan penelitian perubahan garis pantai dengan studi kasus di Sri Lanka dan Indonesia dengan menggunakan metode studi komparasi melalui penelusuran literatur ilmiah. Hasil dari penelitian ini menunjukkan pembangunan pelabuhan merupakan faktor paling berpengaruh dalam perubahan garis pantai di Sri Lanka, sedangkan di Indonesia dipengaruhi oleh faktor konstruksi pantai, estuari sungai, dan kedalaman dasar laut. Perubahan garis pantai di tahun 2031, dan 2041 masing – masing negara diprediksi akan mengalami erosi, abrasi, dan akresi. Dalam hal kebijakan, Perubahan garis pantai di Indonesia akan berpengaruh pada pengelolaan kawasan pesisir, khususnya dalam hal penghitungan Dana Alokasi Umum. Shoreline is a very dynamic geomorphological feature and susceptible to changes caused by natural phenomena or human activities. Shoreline changes will have an impact on the management of coastal areas and threaten the sustainability of coastal resources. Monitoring of shoreline changes can be carried out by using statistical calculation analysis with statistical variables and physical variables. This paper aims to review and compare shoreline change research with case studies in Sri Lanka and Indonesia using the comparative study method through scientific literature review. The results of this study indicate that port construction is the most influential factor in shoreline changes in Sri Lanka, while in Indonesia it is influenced by several factors such as coastal construction, river estuaries, and seabed depth. Coastline changes in 2031 and 2041 for each country are predicted to experience erosion, abrasion and accretion. In terms of policy, changes to the coastline in Indonesia will affect the management of coastal areas, especially in terms of calculating the General Allocation Fund
