Ağva ilçe merkezine ait taşkın yayılım haritalarının ve mevcut binaların taşkın su seviyelerinin tespiti

Taşkınlar, genel olarak yeryüzünün değişik bölgelerinde yağış dengesinin değişmesi, küresel ısınmanın getirdiği iklim değişikliği ve doğal bitki örtüsündeki değişimler sonucunda ani olarak ve belirli periyotlarda meydana gelen, her yıl milyonlarca insanı etkileyen, çevre tahribinin yanı sıra can ve mal kaybına sebep olan ve ekonomiyi olumsuz yönde etkileyen doğal afetlerdir. Dünyada, taşkınların etkilerinden korunmak ve zararlarını azaltmak amacıyla pek çok çalışma yapılmaktadır. Bu çalışmada, İstanbul’un turistik yerleşimi ve iki derenin arasında bulunması sebebiyle de taşkın afeti açısından kritik bir bölgesi olan Ağva için farklı senaryo debileriyle taşkın analizleri yapılmıştır. Taşkın analizleri sonucunda taşkına maruz kalan her bir konut için su seviyeleri belirlenmiştir.

Determination of flood inundation maps and water levels of buildings in Agva town centre

The floods are generally natural disasters that occur at once or at specific periods due to the change of precipitation balance in various regions of the world, the climate change brought by the global warming and the changes on natural vegetation and that affect millions of people every year and lead to loss of life and property as well as environmental damage and adversely affect the economy. So many studies have been carried out with the aim of being protected from effects of the floods and decreasing their damages. In this paper, different scenarios flood discharges were analyzed for Agva which is the touristic peripheral settlement of Istanbul and a critical area in terms of flood disaster due to it’s location between two streams. According to the results of flood analyses, water levels were determined for every dwelling under the effect of flood.
