Abstract

Coastal areas are among the most productive environments, providing ideal conditions for tourism, agricultural, commercial, and industrial activities. Nevertheless, both geological and anthropogenic factors significantly impact the morphology of coastal regions. To recognize these changes, shoreline change analyses play a crucial role in determining the erosion and accretion rates. The Bakırçay Delta, located in the northern Aegean coastal area of Türkiye, has suffered severe degradation in recent years owing to increased settlements and diverse economic activities, including mining, geothermal energy production, and agricultural activities on the coastline of the Bakırçay plain. Seasonally varying high discharges also have led to a higher transport of bedload depositions in the Bakırçay Delta. In this study, the shoreline changes of the Bakırçay Delta were assessed using multitemporal Landsat images and the Digital Shoreline Change Analysis System (DSAS) for the 1975-2022 period. Possible human-induced factors causing the shoreline changes in the Bakırçay Delta were also discussed. Short- and long-term shoreline analyses of the Bakırçay Delta indicated that substantial shoreline changes have occurred in the northern part of the Bakırçay River. Long-term shoreline analyses showed that the highest shoreline accretion occurred along the Yeni Çandırlı Port, whereas the highest shoreline erosion occurred in the northern part of the Bakırçay River between 1975 and 2022. Overall, the Bakırçay Delta coast experienced significant shoreline changes mainly due to human-induced factors, which affected its morphology considerably.
