Özet:

 Cities are witnessing various urban water problems due to reasons such as sudden and high-intensity rainfalls that occur in a short time due to climate change, urban planning policies that are not sensitive to the climate, and inadequate urban drainage systems. There are various approaches to overcome or adapt to these problems. In this context, the study is based on the hypothesis that urban land use decisions should be developed based on the idea of resilience against risks related to climate change, and that risk analysis should be performed first for this purpose. In the study, a search was conducted in the Web of Science WOS database in order to determine the analysis methods related to flood risk and their relations with spatial planning decisions, and the bibliometric data of the obtained publications were taken as basis. In this context, keyword analysis was performed on the studies filtered with the urban flood resistance scan in the VosViewer 1.6.20.0 program and their methods were examined. The flood risk map of Denizli city was created using the Analytical Hierarchy Process AHP, which was determined to be the most used method. The risk map has 4 classes indicating low, medium, high and very high risk areas. As a result of the analysis, it has been determined that very high - risk areas are located in the south and southwest of the city, in areas close to the river and in areas with little or sparse vegetation. The obtained risk map was superimposed with the 125.000 scale master development plan of Denizli city and the spatial plan decisions taken in very high risk areas were evaluated. In this context, it has been determined that the areas with flood risk in the plan largely include urban settlements Current housing areas, Development housing areas and working areas Trade area, TradeResidential area, TradeTourismResidential area. In this context, strategies regarding flood resilience in the urban planning perspective have been developed based on the example of Denizli city.

 Kentler iklim değişikliğine bağlı olarak kısa sürede gerçekleşen ani ve yüksek yoğunluklu yağışlar, iklime duyarlı olmayan kentsel planlama politikaları ve yetersiz kentsel drenaj sistemleri gibi nedenlerle çeşitli kentsel su sorunlarına tanık olmaktadır. Söz konusu sorunların üstesinden gelebilmek veya uyum sağlayabilmek için çeşitli yaklaşımlar bulunmaktadır. Bu kapsamda çalışma iklim değişikliğine bağlı risklere karşı dirençlilik düşüncesine dayalı kentsel arazi kullanım kararlarının geliştirilmesi, bunun için de öncelikle risk analizinin yapılması gerektiği hipotezinden temellenmiştir. Çalışmada taşkın riskine ilişkin analiz yöntemlerinin tespiti ve mekânsal planlama kararları ile ilişkilerinin belirlenmesi amacıyla Web of Science WOS veri tabanında tarama yapılarak, elde edilen yayınların bibliyometrik verisi baz alınmıştır. Bu kapsamda kentsel taşkın direnci taramasıyla filtrelenen çalışmaların VosViewer 1.6.20.0 programında anahtar kelime analizi yapılmış ve yöntemleri irdelenmiştir. En fazla kullanılan yöntem olduğu belirlenen Analitik Hiyerarşi Süreci AHP kullanılarak Denizli kentinin taşkın risk haritası oluşturulmuştur. Risk haritasında düşük, orta, yüksek ve çok yüksek derecede riskli alanları gösteren 4 sınıf saptanmıştır. Analiz sonucunda çok yüksek riskli alanların kentin güney ve güneybatısında akarsuya yakın kesimlerde ve bitki örtüsünün az ya da seyrek olduğu alanlarda yer aldığı tespit edilmiştir. Elde edilen risk haritası Denizli kenti 125.000 ölçekli nazım imar planıyla çakıştırılarak çok yüksek riskli alanlarda alınan mekânsal plan kararları değerlendirilmiştir. Bu kapsamda planda taşkın riski bulunan alanların büyük oranda kentsel yerleşme Mevcut konut alanları, Gelişme konut alanları ve çalışma alanlarını Ticaret alanı, TicaretKonut alanı, TicaretTurizmKonut alanı içerdiği tespit edilmiştir. Bu bağlamda Denizli kenti örneğinden yola çıkılarak kent planlama perspektifinde taşkın dirençliliğine ilişkin stratejiler geliştirilmiştir.
