Çine çayı su kalitesi eğilimleri

Abstract

Bu çalışmada, Büyük menderes akarsuyunun önemli kollarından olan Çine Çayı üzerindeki Kayırlı ve Çakırbeyli su kalitesi gözlem istasyonlarında elde edilen su kalitesi verilerinin mevsimlik ve yıllık ortalama değerlerinin zamansal eğilimleri parametrik-olmayan Mann-Kendall ve Spearman-Rho testleri ile parametrik t-testi kullanılarak incelenmiştir. Bu üç testten benzer sonucu veren en az iki testin sonucuna göre zamansal eğilimin olup olmadığına karar verilmiştir. Ayrıca, su kalitesi parametreleri ile debi arasındaki ilişkiler de incelenmiştir. Çalışmada, pH, elektriksel iletkenlik (EC), sodyum (Na), potasyum (K), kalsiyum+magnezyum (Ca+Mg), karbonat (CO ), bikarbonat (HCO ), klor (Cl), sülfat (SO ) ve bor (B) olmak üzere toplam on parametre incelenmiştir. Dört mevsimin ortalamaları ile bir yıllık ortalama ve on parametre kullanılarak, her bir istasyon için 50 zaman serisi elde edilmiştir. Kayırlı istasyonunda 50 zaman serisinden 19'unda artan, 3'ünde azalan yönde eğilim gözlenmiş iken; Çakırbeyli istasyonunda 50 serinin 6'sında azalan yönde eğilim saptanmıştır. Diğerlerinde ise eğilim olmadığı belirlenmiştir. Her iki istasyonda da su kalitesi parametrelerinin çoğunluğu ile debi arasında negatif bir korelasyon olduğu saptanmıştır.

In this study, temporal trends of water quality parameters observed at Kayırlı and Çakırbeyli water quality monitoring stations in Çine Creek which is one of the important tributaries of Büyük Menderes River were investigated using non-parametric Mann-Kendall and Spearman Rho tests and parametric t-test. The trend analysis were performed on seasonal and annual averages. Whether or not a trend exists is decided upon the results of at least two tests with similar result. The relationships between water quality parameters and river discharge were also examined. The studied parameters are pH, electrical conductivity (EC), sodium (Na), potasium (K), calsium+magnesium (Ca+Mg), carbonate (CO ), bicarbonate (HCO ), chloride (Cl), sulphate (SO ) and boron (B). For each station, 50 time series were constructed using averages of each of four seasons, one annual average and 10 water quality parameters. At Kayırlı out of 50 time series, 19 series increased, 3 series decreased, while decreasing trends in 6 series were detected at Çakırbeyli. Other series stayed unchanged. The most of water quality parameters were negatively correlated with the river discharge at both stations.
