Abstract

İklim değişikliğinden dolayı yağış rejimi de değişmiştir. Bundan dolayı, yeraltı suyunun geri beslenmesinin azaltması, kentleşme, nüfus artışı, tarımsal ve endüstriyel faaliyetlerin artması dünyadaki yeraltı suyu kalitesini olumsuz etkilemiştir. Bu nedenle, yeraltı suyu kirliliğine karşı hassasiyetin değerlendirilmesi, yeraltı suyu kaynaklarının kirlenmeye karşı yönetimi ve korunması için etkili bir stratejinin ifa edilmesi zorunludur. Yeraltı suyunun potansiyel kirleticilere karşı hassasiyetini değerlendirmek için yaygın olarak kullanılan modellerden biri DRASTIC’dir. Harran Ovasının yeraltı suyu kirlilik hassasiyetini belirlemek için Orijinal Drastik Model (ODM) ve Modifiye Drastik Model (MDM) test edilmiştir. Sonuç olarak, Harran ovasının yaklaşık yarısına yakının özelikle yerleşimlere yakın olan alanlardaki yeraltı suyu kirleticilere karşı hassas olduğu tespit edilmiştir
