Özet:

 Van is one of the city that earthquakes has been observed frequently in Turkey. In the last century more than five earthquakes has happened around the city, and significant loss of life and property occurred. Earthquake that caused deformation of the sewage - drinking water systems, in Van at 2011, Pazarcık-Elbistan epicenters earthquakes at 2023, once again showed us importance of these systems and negative effects during their losses.The aim of this study is to evaluate earthquake performance of the pipes in the sewerage infrastructure in the central districts of Van, by using geographic information system GIS based multi-criteria decision analysis MCDA. The model created in the study includes three separate factors, these are; distance to active fault lines, pipe types and soil properties. The earthquake susceptibility map of the sewer pipe systems was obtained by using the comparison matrix, which consists of comparing all defined factors with each other. According to the susceptibility map, 45 of the pipe lines close up to 4 km to the fault lines, may suffer high or very high damage by earthquakes produced by these fault lines. Especially the sewerage systems located near to the Lake Van in İskeleköy, and close to Edremit district northern border are in high risk. Most importantly, the western parts of İpekyolu district, the southern parts of Tusba district, and the northeastern areas of Edremit district, where urbanization is most intense, and which contains constitute 39 of the total sewerage infrastructure are at high risk.The method applied in the study allowed to obtain reliable and healthy information against natural disasters. The vulnerability model produced in this context will play an important role in the implementation of the infrastructure pipes before the earthquake in a much more planned and healthy way, especially in highly sensitive areas.

 Van ili depremlerin sıklıkla gözlendiği şehirlerimizden birisidir. Son 100 yıl içerisinde Van ili ve çevresinde beşten fazla yıkıcı deprem meydana gelmiş, önemli can ve mal kayıpları yaşanmıştır. Hem 2011 yılında Van ilinde yaşanan depremlerde hem de 2023 yılında yaşadığımız Pazarcık-Elbistan merkez üslü depremlerde kanalizasyon sistemlerinden meydana gelen deformasyonun afetin boyutunu ve etkisini çok fazla arttırdığı görülmüştür. Bu çalışmanın amacı, Van merkez ilçelerinde yer alan kanalizasyon alt yapısındaki boruların deprem performansını coğrafi bilgi sistemlerinin kullanarak çok kriterli karar analizi ile değerlendirilmesidir. Çalışmada oluşturulan model üç ayrı faktörü içerir, bunlar; aktif fay hatlarına mesafe, boru tipleri ve zemin özellikleridir. Kanalizasyon boru sistemlerinin deprem duyarlık haritası, tüm tanımlı faktörlerin birbiri ile kıyaslanmasından oluşan karşılaştırma matrisi kullanılarak elde edilmiştir. Duyarlılık haritasına göre, fay hattına 4 kmden daha yakın mesafede konumlanmış kanalizasyon alt yapısında yer alan boruların, fay hatları tarafından üretilen depremlerde 45nin yüksek veya çok yüksek hasar görebileceği şeklindedir. Özellikle Van Gölüne yakın kesimlerde yer alan İskele Mahallesi ve Edremit ilçe sınırlarının kuzey kesimlerinde yer alan kanalizasyon sistemleri yüksek risk altındadır. En önemlisi kentleşmenin en yoğun olduğu İpekyolu ilçesinin batı kesimleri, Tuşba ilçesinin güney kesimleri ile Edremit ilçesinin kuzeydoğu alanları ise yüksek risk altında olup, bu alanlar toplam kanalizasyon alt yapısının 39unu oluşturmaktadır. Çalışmada uygulanan yöntem deprem esnasında gelişen deformasyonlara karşı güvenilir ve doğru bilgilerin elde edilmesine imkân tanımıştır. Bu bağlamda üretilen duyarlılık modeli ile hasar görebilirlik analizi, özellikle yüksek duyarlı alanlarda, alt yapı borularının depremden önce yapılacak olan uygulamaların çok daha düzenli ve planlı bir şekilde yürütülmesinde önemli rolleri olacaktır.
