Özet:

 Bartın province, located in the Western Black Sea Region as a geographical location, has been affected socially and economically at a detectable level due to earthquake, flood, and landslide disasters in the past years. Such disasters connected with the climatic conditions, vegetation, and topographic structure of Western Black Sea Basin, a tectonically active region, are likely to affect the alluvial-based Bartın province more in terms of frequency and severity in the future. For this reason, unfavorable soil conditions should be well known in the seismic design process of engineering structures to be built in the region and in the studies to be carried out to reduce the adverse effects of floodings based on heavy rains. In this study, the general soil structure in the dense residential areas in Bartın city center and Amasra district were analyzed using some important dynamic parameters in geotechnical earthquake engineering. The risk assessment of the geotechnically problematic andor more sensitive building areas was determined using the data obtained from the ground survey reports in the pilot study areas. In addition, some overflowing and landslide events that occurred after the last flooding in June 2022 in the region were interpreted depending on the updated pictures and impressions obtained from the field conditions. It was evaluated that the results and suggestions presented within the scope of the study will guide the engineers designing engineering structures to be built in the region, as well as the researchers analyzing the disaster situation of the region and the city planners involved in the determination of settlement points.

 Coğrafi konum olarak Batı Karadeniz Bölgesinde bulunan Bartın ilinde geçmiş yıllarda gerçekleşen deprem, sel, heyelan gibi afetlerden dolayı, bölge sosyal ve ekonomik anlamda hissedilir düzeyde etkilenmiştir. Tektonik olarak aktif bir bölge olan Batı Karadeniz Havzasının iklim koşulları, bitki örtüsü ve topoğrafik yapısı nedeniyle yaşanan bu tür afetlerin gelecekte alüvyal tabanlı Bartın ilini sıklık ve şiddet anlamında daha fazla etkilemesi muhtemeldir. Bu sebeple bölgede yapılacak mühendislik yapılarının sismik tasarım sürecinde ve şiddetli yağışlara bağlı meydana gelen su baskınlarının olumsuz etkilerini azaltmak için yapılacak çalışmalarda, elverişsiz zemin koşullarının iyi bilinmesi gerekir. Yapılan bu çalışmada Bartın şehir merkezi ve Amasra ilçesinde bulunan yoğun yerleşim alanlarındaki genel zemin yapısı, geoteknik deprem mühendisliği açısından önemli olan bazı dinamik parametreler kullanılarak analiz edilmiştir. Pilot inceleme alanlarında yapılmış zemin etüt raporlarından elde edilen verilerin analiz edildiği bu araştırmada, geoteknik açıdan problemli veveya yapı açısından daha duyarlı yerleşim sahalarının risk değerlendirmesi yapılmıştır. Ayrıca, bölgede en son gerçekleşen Haziran 2022 sel afeti sonrası oluşan bazı taşkın ve heyelan olayları, arazi koşullarında edinilen güncel resimler ve izlenimlere bağlı olarak yorumlanmıştır. Çalışma kapsamında sunulan sonuç ve önerilerin, bölgede inşa edilecek mühendislik yapılarını tasarlayan mühendislerin yanı sıra bölgenin afet durumunu analiz eden araştırmacılara ve yerleşim noktalarının belirlenmesinde görev alan şehir planlayıcılarına yol gösterici olacağı değerlendirilmiştir.
