Abstract

This study examines the effects of the Boğaçay Project, launched in 2017 on the Konyaaltı Coast of Antalya, on shoreline evolution using a multi-model approach. The project interrupted the natural sediment cycle, impacting both short-term morphological changes and long-term coastal stability. This study evaluates these effects through integrated models. Morphological changes from excavations at the estuary cut off natural sediment transport and were integrated with (1) the Pelnard-Considère model for long-term coastal evolution, (2) the SWAT model for basin-scale transport analysis, and (3) the XBeach model for simulating coastal hydrodynamics and morphodynamics. The study employed XBeach-based high-resolution simulations to represent physical processes, elucidate the current situation, and facilitate the testing of shoreline evolution scenarios under various engineering interventions. The model, calibrated using satellite images, coastline data, and topographic scans, showed strong agreement between numerical outputs and observations, thereby enhancing model accuracy. Results indicated an average coastal retreat of 21.7 meters over the 3 years following the project. While artificial sediment feeding slowed regression by 58%, XBeach simulations revealed that the deepened estuary worsened erosion in the east by altering wave dynamics diffraction. This integrated modeling approach highlights the critical role of sediment dynamics in coastal stability, underscoring the need for revised coastal management policies. The study identifies the spatial and temporal dynamics of shoreline changes and simulates the basic morphodynamic processes, predicting the effects of intervention scenarios. This comprehensive modeling enables the development of sustainable management strategies that protect ecosystem integrity and inform engineering solutions in human-degraded coastal systems.

Abstract

Urbanization, a prehistoric concept, has evolved to encompass various dynamics influenced by technology, population growth, and lifestyle, significantly affecting a community's cultural heritage. The study uses satellite imagery from Google Earth Pro to assess the impact of urbanization on Kaleiçi, Antalya's historic district, revealing an increase in new constructions and loss of green space since 2004. The study used Matlab-based temporal comparison of satellite imagery to analyze the effects of urbanization in Kaleiçi over 20 years. Roland Barthes, a cultural theorist, encouraged architects and planners to combine semiology with urban theory. Barthes' semiotic theory was applied to the study of Antalya's old city, Kaleiçi, indicating that efforts have been made to conserve Kaleiçi, a city of historical and cultural value, despite changes in its meaning, much as Barthes' metaphor of the Argo ship. Over the last two decades, Kaleiçi has seen a slight (5.6280%) increase in new structures, reflecting the authorities' effective balance between expansion and preservation of the area's distinctive semiotic character. This study contributes to the growing body of knowledge concerning the consequences of urbanization on cultural assets and provides valuable insights for future conservation programs.
