In this study, dissolved nutrients concentrations weremeasured monthly at downstream points of the tworegional rivers (the Berdan and Göksu rivers) flowing into the Cilician Basin of the North-eastern (NE) Mediterranean Sea. The dissolved nutrients data obtained between September2021 and August 2022 were used to determine riverinenutrient fluxes. This study showed that spatial and temporalvariations were recorded in nutrients concentrations of thetwo regional rivers with the maximum values consistentlyrecorded in the Berdan River having lower volume fluxes.The annual nutrient inputs of the two regional riversindicated that higher amounts of dissolved nutrients werecarried by the Göksu River due to its higher volume fluxrate. The calculated molar ratios from total nitrogen (TN)and phosphorus (TP) fluxes ranged from 13 in the GöksuRiver to 22 in the Berdan River. The higher TN/TP molar ratiocompared to the classic Redfield Ratio of N/P in the BerdanRiver is very likely to modify nutrient dynamics leadingto further eutrophication in the shelf waters of the NE Mediterranean Sea.
