Abstract

Arazi kullanımı ve yönetimi, toprakların strüktürel özellikleri ve erozyona duyarlılıkları bakımından önemli bir değişkendir. Bu çalışmada, WEPP (Water Erosion Prediction Project, 2012) Hillslope modeli kullanmak suretiyle farklı arazi kullanımı altındaki arazilerde meydana gelen toprak kayıpları ve yüzey akış miktarları tahmin edilmiştir. Çalışma, Karadeniz ile İç Anadolu bölgesi arasında yer alan Tokat-Sivas karayolunun 20.km mesafesinde yürütülmüştür. 2010-2015 yılları arasındaki iklim verileri kullanılmıştır. Ortalama yıllık yağış 385 mm’dir. Toprak örnekleri farklı arazi kullanımlarının olduğu 3 farklı araziden 0-20 cm ve 20-40 cm derinlikten alt ve üst olmak üzere 18 noktadan alınmıştır. Yamacın uzunluğuna ve eğimine bağlı olarak en yüksek toprak kayıpları tarım, en düşük toprak kayıpları ise orman arazisinde tahmin edilmiştir.
