Abstract: <\/strong>The aim of this study is the detection of coastal changes in and around the ancient city of Phaselis between the years 1957, 1981, 1992, 2009 and 2019. A literature review was carried out and it was determined that the Digital Shoreline Analysis System (DSAS) was the most appropriate method for detecting coastal change. DSAS, an extension of the ArcGIS program, is a method that effectively calculates changes in coastal shorelines from past years. In this study, the most preferred statistical analyses within the DSAS analysis method were used, including Net Shoreline Movement (NSM), End Point Rate (EPR), and Shoreline Change Envelope (SCE). While the DSAS method often relies on Landsat satellite imagery, in this study, aerial photographs from the General Directorate of Mapping (HGM) were used, providing more detailed data for the years 1957, 1981, 1992, 2009, and 2019. The reason for not using Landsat satellite images is that the study area covers a small geographical area. This limitation prevents Landsat satellite imagery from providing a detailed view. During the analyses, the study area was divided into four sections: Bostanl\u0131k Bay, City Harbor, Northern Harbor and Cennet Bay. Bostanl\u0131k Bay was further divided into two parts, labelled A and B, for investigation. The results of the analyses showed that sedimentation occurred in certain areas of the ancient city of Phaselis and its surroundings. In other areas, erosion occurred. The occurrence of sedimentation is attributed to both natural processes and anthropogenic activities. The most prominent example of anthropogenic activity can be seen along the coast of Cennet Bay.<\/p>\n

Yap\u0131lan literat\u00fcr \u00e7al\u0131\u015fmas\u0131 sonucunda k\u0131y\u0131 de\u011fi\u015fimini tespit etmek i\u00e7in en uygun y\u00f6ntemin Digital Shoreline Analysis System (DSAS\/Dijital K\u0131y\u0131 \u00c7izgisi Analiz Sistemi) oldu\u011fu tespit edilmi\u015ftir. ArcGIS program\u0131n\u0131n bir uzant\u0131s\u0131 olarak kullan\u0131lan DSAS, ge\u00e7mi\u015f y\u0131llara ait k\u0131y\u0131 \u015feridi de\u011fi\u015fimlerini en uygun bi\u00e7imde hesaplayan bir y\u00f6ntemdir. DSAS analiz y\u00f6ntemi i\u00e7inde en \u00e7ok tercih edilen istatistik analizleri olan Net K\u0131y\u0131 Hareketi\/Net Shoreline Movement (NSM), Biti\u015f Noktas\u0131 Oran\u0131\/End Point Rate (EPR) ve K\u0131y\u0131 \u015eeridi De\u011fi\u015ftirme Zarf\u0131\/ Shoreline Change Envelope (SCE) bu \u00e7al\u0131\u015fmada kullan\u0131lm\u0131\u015ft\u0131r. DSAS y\u00f6ntemi uygulan\u0131rken daha \u00e7ok Landsat uydu g\u00f6r\u00fcnt\u00fclerinden yararlan\u0131l\u0131r. Ancak bu \u00e7al\u0131\u015fmada daha ayr\u0131nt\u0131l\u0131 veri sa\u011flayan Harita Genel M\u00fcd\u00fcrl\u00fc\u011f\u00fc\u2019nden (HGM) temin edilmi\u015f olan 1957, 1981, 1992, 2009 ve 2019 y\u0131llar\u0131na ait hava foto\u011fraflar\u0131 kullan\u0131lm\u0131\u015ft\u0131r. Landsat uydu g\u00f6r\u00fcnt\u00fcs\u00fcnden yararlanmaman\u0131n nedeni \u00e7al\u0131\u015fma alan\u0131n k\u00fc\u00e7\u00fck bir sahay\u0131 kapsamas\u0131d\u0131r. Bu da Landsat uydu g\u00f6r\u00fcnt\u00fclerinin ayr\u0131nt\u0131l\u0131 bir g\u00f6r\u00fcnt\u00fc almas\u0131na engel olmaktad\u0131r.

Bostanl\u0131k Koyu kendi i\u00e7erisinde A ve B olarak iki k\u0131s\u0131mda incelenmi\u015ftir. Yap\u0131lan analizler sonucunda ise Phaselis Antik Kenti ve \u00e7evresinin belli alanlarda birikme olurken belli alanlar\u0131nda ise erozyon meydana gelmi\u015ftir. Birikme olay\u0131n\u0131n ger\u00e7ekle\u015fmesinin nedeni do\u011fal s\u00fcre\u00e7lerin yan\u0131 s\u0131ra antropojen faaliyet\u00adlerdir. Antropojenik faaliyetlerin en iyi \u00f6rne\u011fini ise Cennet Koyu k\u0131y\u0131lar\u0131nda g\u00f6r\u00fcl\u00fcr.<\/p>\n
