In Romania, 62% of the surface is occupied by land used in agriculture. This clearly shows the impact of these activities on the environment. Although agricultural activities ensure the living for a considerable part in Romanian population, the agriculture also contributes to environmental damage and decreased quality of life. Fertilizers have been used widely in agriculture, disregarding the specific needs of the crop, the time of their application and the way they should be applied. Therefore, the most intensive polluting effect is caused by excessive use of nitrates. Accumulation and uncontrolled migration in soil and groundwater of the fertilizers can cause significant disturbance parameters of environmental factors. The main function of the chemical fertilizers is to prevent lack of nutrients from the ground. Because the chemical fertilizers are easily washed out by rain they can cause pollution in surface waters. This paper presents an application of the DHI tool, Mike 11, for the simulation of water quantity and quality of river Gladna and Surduc Lake. The results show that this model is able to capture the water quality of the river, as per the observed values, and it is possible to be used in the future to predict the impact of a certain pollutant on the river Gladna and Surduc Lake. The results of this study show the possibility to develop "what-if" analyses, which can help decision makers to choose the best adaptation strategy.
