Abstract (2. Language): 
In this paper, variability in monthly water quality records at Durucasu monitoring station on the Yeşilırmak River was analyzed by considering the Mann-Kendal (MK) and Theil-Sen Slope estimator (TSE) statistical approaches to detect the direction and magnitude of an available monotonic trend in any given data. The pH, chlorides, sulfates and SAR data sequences for some months had statistically significance upward trend when there was a decreasing trend in streamflow data of the nine months. The largest percent change in streamflow data was found as 153% in November, whereas July in the pH, June in chlorides and January in sulfates and SAR had the maximum percent change.
Abstract (Original Language): 
Bu çalışmada, Yeşilırmak nehri üzerindeki Durucasu su kalite ölçüm istasyonunun aylık su kalite değerlerindeki değişkenlik, Mann-kendal ve Theil-Sen eğim tahmin istatistik yaklaşımları kullanılarak mevcut verideki doğrusal trendin yön ve büyüklüğünü ortaya çıkarmak amacıyla analiz edildi. Bazı ayların pH, klor, sülfat ve SAR verilerinde istatistiki anlamda önemli artan trend, dokuz ayın akım değerlerinde ise azalan trend bulundu. Akım verisindeki en büyük yüzde değişim Kasım ayında % 153 olarak saptandı, bununla birlikte Temmuz ayında pH, Haziran ayında klor, Ocak ayında sülfat ve SAR verisi maksimum yüzde değişime sahip oldu.
