Kurtboğazı ve Çaml ı dere Barajlar ı nda Klorofil a' n ı n Tahmini

Abstract

Kurtboğ az ı ve Çaml ı dere barajlan içir ı kurulan çoklu doğ rusal ve doğ rusal olmayan regresyon modeilerinden yararlan ı larak, suyun baz ı fiziksel ve kimyasal parametreleri ile klorofil a aras ı ndaki iliş kiler değ erlendirilmiştir Bu iki farkl ı yaklaşı mdaki amaç klorofil a'n ı n güvenilir bir şekilde tahmin edilmesidir. Belirleme katsay ı lar ı Kurtboğ az ı ve Çaml ı dere baraj gölleri için, do ğ rusal çoklu regresyon modelinde s ı ras ı yla %95 ve Ü/o 8 2 olarak bulunurken, doğ rusal olmayan regresyon modellerinde %85 ve %70 olarak bulunmu ştur.

Prediction of Chlorophyll a in Kurtboğazı and Çamlıdere Reservoirs

Abstract

he relationships between chlorophyll a and some physical and chemical properties of water were investigated by using multiple linear and nonlinear regression models in Kurtbo ğ az ı and Çaml ı dere reservoirs With these two different approaches chlorophyll a was aimed to be estimate more accurately. The determination coefficients were found as 95% and 82% for multiple linear regression models while 85` /0 and 7 O % for nonlinear regression models for Kurtbo ğaz ı and Çaml ı dere reservoirs, respectively.

Keywords
