As regards the assessment of water quality and its changes (both in cross- and lengthwise-profile), mathematical modelling is a relatively recent method. It is based on simulation of water movement in the river bed and on consequent modelling of diffusion of pollutants. Mathematical modelling enables to calculate a continuous lengthwise-profile of water quality in the water course and to identify the impact of various pollution sources on water quality. It also makes possible to predict water quality changes over the time under changing external conditions.
