Özet:

 The analytical hierarchy AHP is a multi-criteria decision-making MCDM method. It provides clear guidance to decision-makers, especially when more than one factor needs to be evaluated. The role of this method in flood risk analysis is based on calculating the relative importance levels of different geographical factors. In the study, eight different geographical factors that may affect flood risk were determined. These factors may include precipitation amount, topographic structure, stream proximity, and soil structure. Comparisons were made between these factors and AHP, and the magnitude of the effect of each factor on flood risk was determined. The main advantage of AHP is that it allows decision-makers to objectively rank the importance of these factors by putting expert opinions into a numerical framework. In this way, the most critical flood risk factors can be highlighted. In this study, the flood risk of Kalburt Stream, located in the İnegöl district of Bursa province, was tried to be determined with the support of AHP and GIS. After selecting the importance order of the factors with AHP, the geographical factors were evaluated in the GIS software ArcMap 10.2.2 program by taking this order into consideration. ArcMap is a powerful tool used in visualizing and analyzing geographic data and has been used effectively in creating flood risk maps. In this study, the importance of geographic factors affecting flood risk was ranked using the analytical hierarchy method AHP, and a flood risk map was created using Geographic Information Systems GIS, which is in line with this ranking. AHP is an essential tool in flood risk analysis in terms of integrating a large number of factors and determining the relative importance of each factor. This study demonstrates how AHP can be used effectively in flood risk management and shows the power of a GIS-supported approach for regional risk analysis.

 Analitik hiyerarşi yöntemi AHP, çok kriterli karar verme ÇKKV yöntemlerinden biridir ve özellikle birden fazla faktörün değerlendirilmesi gerektiğinde karar vericilere net bir rehberlik sağlar. Bu yöntemin taşkın riski analizindeki rolü, farklı coğrafi faktörlerin göreli önem derecelerini hesaplamaya dayanır. Çalışmada, taşkın riski üzerinde etkili olabilecek 8 farklı coğrafi faktör belirlenmiştir. Bu faktörler arasında yağış miktarı, topografik yapı, akarsu yakınlığı, zemin yapısı gibi unsurlar yer alabilir. AHP ile bu faktörler arasındaki karşılaştırmalar yapılmış ve her bir faktörün taşkın riski üzerindeki etkisinin büyüklüğü belirlenmiştir. AHPnin temel avantajı, karar vericilerin uzman görüşlerini sayısal bir çerçeveye dökerek, bu faktörlerin önem sıralamasını objektif bir şekilde yapmasına olanak tanımasıdır. Bu sayede, en kritik taşkın riski faktörleri öne çıkarılabilir. Bu çalışmada Bursa ili İnegöl ilçe sınırlarında yer alan Kalburt Deresinin taşkın riski AHP ve CBS desteğiyle belirlenmeye çalışılmıştır. Çalışma da faktörlerin önem sıralaması AHP ile belirlendikten sonra, bu sıralama dikkate alınarak coğrafi faktörler CBS yazılımı olan ArcMap 10.2.2 programında değerlendirilmiştir. ArcMap, coğrafi verilerin görselleştirilmesi ve analiz edilmesinde kullanılan güçlü bir araçtır ve taşkın risk haritalarının oluşturulmasında da etkili bir şekilde kullanılmıştır. Bu çalışmada, analitik hiyerarşi yöntemi AHP ile taşkın riski üzerinde etkili olan coğrafi faktörlerin önem sıralaması yapılmış ve bu sıralama doğrultusunda Coğrafi Bilgi Sistemleri CBS kullanılarak taşkın risk haritası oluşturulmuştur. AHP, taşkın riski analizlerinde, çok sayıda faktörün entegre edilmesi ve her bir faktörün göreli öneminin belirlenmesi açısından önemli bir araçtır. Bu çalışma, taşkın risk yönetiminde AHPnin nasıl etkili bir şekilde kullanılabileceğini göstermekte ve bölgesel risk analizi için CBS destekli bir yaklaşımın gücünü ortaya koymaktadır.
