“…In this case, using the WaTEM model, the CeVI vulnerability values are lower. The Eraclea Minoa beach has a logarithmic spiral shape, and during recent years, it was struck by erosion phenomena [43]. This dissipative beach is located far from defense structures and harbors, and for this reason the longitudinal sediment transport is not influenced.…”

In recent decades, coastal erosion phenomena have increased due to climate change. The increased frequency and intensity of extreme events and the poor sediment supply by anthropized river basins (dams, river weirs, culverts, etc.) have a crucial role in coastal erosion. Therefore, an integrated analysis of coastal erosion is crucial to produce detailed and accurate coastal erosion vulnerability information to support mitigation strategies. This research aimed to assess the erosion vulnerability of the Sicilian coast, also including a validation procedure of the obtained scenario. The coastal vulnerability was computed by means of the CeVI (Coastal Erosion Vulnerability Index) approach, which considers physical indicators such as geomorphology and geology, coastal slope, sea storms, wave maxima energy flux and sediment supply to river mouths. Each indicator was quantified using indexes which were assessed considering transects orthogonal to the coastline in 2020. These transects were clustered inside natural compartments called littoral cells. Each cell was assumed to contain a complete cycle of sedimentation and not to have sediment exchange with the near cells. Physical parameters were identified to define a new erosion vulnerability index for the Sicilian coast. By using physical indexes (geological/geomorphological, erosion/sediment supply, sea storms, etc.), the CeVI was calculated both for each littoral cell and for the transects that fall into retreating/advancing coastal areas. The vulnerability index was then validated by comparing CeVI values and the coastline change over time. The validation study showed a direct link between the coastline retreat and high values of CeVI. The proposed method allowed for a detailed mapping of the Sicilian coastal vulnerability, and it will be useful for coastal erosion risk management purposes.

“…Nilai laju perubahan garis pantai yang diperoleh dari NSM dan beberapa metode pendekatan lain dapat digunakan sebagai dasar pengelolaan dan konservasi kawasan pesisir. Nilai NSM dapat menunjukkan proses dominan yang berlangsung dan berpengaruh terhadap dinamika pesisir (Manno et al, 2022) (Hegde & Akshaya, 2015) .…”

Kawasan pesisir menjadi salah satu area yang paling rentan terhadap ancaman bencana akibat percepatan perubahan iklim. Salah satu ancaman yang hampir terjadi di seluruh Kawasan pesisir di dunia adalah erosi pantai. Kawasan Pesisir Kabupaten Bantul, DIY menjadi salah satu area yang terdampak cukup parah oleh erosi pantai. Penelitian ini bertujuan untuk (1) Mengetahui proses dinamika pesisir di Kawasan Pantai Pandansimo ; (2) Memetakan tingkat kecepatan abrasi di Pantai Pandansimo, dan (3) Mengetahui penyebab utama dari proses erosi pantai yang terjadi. Citra satelit resolusi tinggi Pleiades dengan resolusi spasial 50cm digunakan untuk mengetahui perubahan garis pantasi secara temporal. Selain itu, citra satelit yang diperoleh dari Google Earth juga digunakan untuk analisis dari tahun 2010-2021. Perubahan garis pantai dihitung menggunakan software DSAS. Data morfologi detail didapatkan dari hasil akuisisi foto udara menggunakan pesawat tanpa awak multirotor. Berdasarkan hasil analisi diketahui bahwa proses dinamika pesisir didominasi oleh proses erosi pantai. Tercatat nilai kemunduran garis pantai rerata sebesar 2.46 meter/tahun. Erosi pantai yang terjadi disebabkan oleh beberapa faktor hidrodinamik dan morfodinamik seperti peningkatan kejadian gelombang ekstrem, berkurangnya suplai sedimen fluvial, dan fenomena perubahan iklim.
