Özet:

 Water is of vital importance for all living things to survive. Changes in the ecosystem along with the increasing population have made it necessary to protect and monitor water resources. Determining the changes in water quantity and quality in any region as a result of natural or artificial effects is important for sustainability. In this study, some water quality parameters of the Yeşilırmak River in terms of agricultural irrigation were investigated and a trend analysis was made. For this purpose, the parameters analyzed by the State Hydraulic Works DSİ at the Water quality observation station numbered 47-00-27 located in Çarşamba district of Samsun province of Yeşilırmak river were used. Within the scope of the study, were used that flow, pH, electrical conductivity, sodium, calcium, magnesium, potassium, chlorine, carbonate, bicarbonate, sulfate, boron, sodium absorption rate and percent sodium parameters determined between 1995 and 2015. In the study, the Mann-Kendall method, which is widely used in parametric and non-parametric analyses, was used for trend analysis of the parameters. Trend analysis results were evaluated in five levels of significance. According to the analysis results, a significant positive trend occurred in water flow rate in January and pH and carbonate content in February. A significant negative trend occurred in the electrical conductivity value and calciummagnesium content of water in January. No significant trend was detected in other results. It was noteworthy that there were no significant trends in the months of the irrigation season.

 Su bütün canlıların yaşamlarını sürdürebilmesi için hayati bir öneme sahiptir. Artan nüfusla birlikte ekosistemde meydana gelen değişimler su kaynaklarının korunmasını ve izlenmesini zorunlu hale getirmiştir. Doğal veya suni etkiler neticesinde herhangi bir bölgedeki su miktarında ve kalitesinde meydana gelen değişimlerin belirlenmesi sürdürülebilirlik için önemlidir. Bu çalışmada Yeşilırmak nehrinin tarımsal sulama açısından bazı su kalite parametreleri araştırılarak trend analizi yapılmıştır. Bu amaç doğrultusunda Yeşilırmak nehrinin Samsun ili Çarşamba ilçesinde bulunan 47-00-27 nolu Su kalitesi gözlem istasyonunda Devlet Su İşleri DSİ tarafından analiz edilen parametreler kullanılmıştır. Çalışma kapsamında 1995-2015 yılları arasında belirlenmiş olan akım, pH, elektriksel iletkenlik, sodyum, kalsiyum, magnezyum, potasyum, klor, karbonat, bikarbonat, sülfat, bor, sodyum absorbsiyon oranı ve yüzde sodyum parametreleri kullanılmıştır. Çalışmada parametrelerin trend analizi için, parametrik ve non-parametrik analizlerde yaygın olarak kullanılan Mann-Kendall yöntemi kullanılmıştır. Trend analizi sonuçları anlamlılık düzeyine beş sınıfta değerlenlendirilmiştir. Analiz sonuçlarına göre suyun debisinde ocak ayında, pH ve karbonat içeriğinde ise şubat ayında anlamlı pozitif trend meydana gelmiştir. Suyun elektriksel iletkenlik değeri ile kalsiyummagnezyum içeriğinde ocak ayında anlamlı negatif trend meydana gelmiştir. Diğer sonuçlarda anlamlı bir trend tespit edilmemiştir. Sulama sezonu olan aylarda anlamlı trendlerin olmaması dikkat çekmiştir.
