The results obtained in the design and calibration of a deterministic water quality model from the Llobregat River (Spain) are presented. The water quality indicators studied are dissolved oxygen, biochemical oxygen demand, ammonia, nitrite, nitrate, phosphate, and heterotrophic bacteria. The factors which describe the rates of the transformation processes are of two types: first‐order and Michaelis‐Menten kinetics. A decomposition process is applied to the model for calibration. The inclusion in the model of heterotrophic bacteria shows good predictive capacity to describe the behaviour of the biological processes in the river. The proposed model gives a correct evaluation of the indicators studied, and may be used in water quality management.
