Abstract: Modelling is one of the tools that contribute to analysing the fluctuation of rivers water quality. Knowledge on the quality of water bodies is very important for the implementation of the European Union Water Framework Directive’s requirements. There was employed ATV-DVWk model simulating the fluctuation of nitrates and ammonium ions in rivers Zeimena and Nevėzis. There were introduced more than 50 parameters characterizing the physical-geographical, climatic conditions, anthropogenic activities as well as morphometric conditions of the watercourses analyzing the stretches of the investigated rivers. Summarizing the modelling results obtained, it could be stated that ATV-DVWk model is suitable for Lithuanian conditions. Maximum divergence among the values of biogenic substances concentrations obtained using a modelling simulation method and direct measurements have not exceeded 38 %.
