THE IMPORTANCE OF SOCIO-ECONOMIC AND DEMOGRAPHIC PROFILES IN FLOOD RISK ASSESSMENT

Abstract

Flood management planning in general primarily focuses on physical damage and structural measures accordingly. While such an approach is necessary, there is a great need for more knowledge to take sufficient precautions. Flood risk maps ensures key information in terms of flood management plans. Therefore, the boundary of inundation area, assets in the region and risk promoting features of population in the flood zone should be evaluated together to estimate flood risk is the closest to truth.

‘‘Nothing cannot sustain its existence which has not a sustainable structure in the nature’’ that the fact in mind, in order to maintain the presence of assets and activities in a floodplain, it is necessary to implement planning decisions that are compatible with the structure of population living in the region.

In this study, we discuss the importance of detailed interpretation of the socio-economic and demographic profiles (age, education level, gender, income etc.) of the population living in the basin in terms of evaluating flood risk.

TAŞKIN RİSKİNİN BELİRLENMESİNDE SOSYO-DEMOGROFİK VE SOSYO-EKONOMİK ÖZELLİKLERİN ÖNEMİ

Öz

Taşkın yönetimi planlamaları genel olarak öncelikli fiziksel zarar görebilirliğin ve buna bağlı olarak yapısal önlemlerin üzerinde yoğunlaşmaktadır. Böyle bir yaklaşım gerekli olmakla beraber yetkin önlem ve planlama kararlarının alınması/uygulanması için birçok bilgiye daha ihtiyaç duyulmaktadır. Özellikle taşkın yönetim planları açısından anahtar bilgi niteliği taşıyan taşkın risk haritalarının üretilmesinde, sel havzasının su altında kalması muhtemel alan sınırları içerisinde kalan varlıkların fiziksel zarar görebilirlikleri ile nüfusun sosyo-demografik ve sosyo-ekonomik durumunun risk arttırıcı yönünün değerlendirilmesi, taşkın riskinin gerçeğe en yakın doğrulukta tahmin edilmesini sağlayacaktır.

“Doğada sürdürebilir yapıda olmayan hiçbir şey varlığını devam ettiremez” gerçeğinden hareketle bir havza sisteminde var olan varlıkların ve faaliyetlerin mevcudiyetini koruyabilmesi ve devamlılığının en güvenli koşullarda sağlanabilmesi için bölgede yaşayan nüfusun yapısıyla uyumlu planlama kararlarının uygulanması gerekmektedir.

Bu gereklilikten hareketle, bu çalışma da taşkın riskinin tespit edilmesinde sel havzasında yaşayan nüfusun sosyal şartlarının bilinmesinin ve taşkın zararlarının meydana gelmesinde nüfusun özelliklerinin muhtemel etkisinin dikkate alınmasının önemi tartışılmıştır.
