Özet

@ 2018 Scibulcom Ltd. All Rights Reserved.In this study it has been performed 14 sampling and measurements between 2014-2017 years with seasonal periods, at the point which river Yesilirmak is poured itself into the Black Sea, Carsamba district of Samsun. Temperature, pH, electrical conductivity, dissolved oxygen, turbidity, total hardness, total suspended solid (TSS), sulphate, chlorophyll-a, nitrate (NO3 --N), nitrite (NO2 --N), ammonium (NH4 +-N), o-phosphate (o-PO4 3--P) and silicate (Si) water quality parameters were measured within this study. Seasonal average concentrations were compared with limit values of the water quality criterias according to relevant regulations of legislation in force. Moreover, characteristic values were calculated for NO3 --N, NO2 --N, NH4 +-N, o-PO4 3--P and Si parameters in Yesilirmak river, as 89.43, 1.79, 18.09, 7.00, and 385 uμM, respectively. Furthermore, dissolved nutrients transported to the Black Sea by Yesilirmak were calculated using seasonal flow. Annual average loads (t) for NO3 --N, NO2 --N, NH4 +-N, o-PO4 3--P, Si and TSS were calculated as 4373, 51, 336, 267, 36324, and 45775, respectively.
