Waste water, discharged into the river system is in processes of transport and mixing. After fully cross mixing, the pollution transport is one-dimensional. The aim of the study was to model the discharge, salinity and biochemical oxygen demand and dissolved oxygen (BOD and DO) loads along the Neretva River, on the section of Mostar to Žitomislić. MIKE-11 a one- dimensional hydrodynamic simulation program was utilized to model stream flow transport and water quality processing in the river system. Hydrodynamic Modele (HD) was applied to calculate water level and flow for the river. Advection-Dispersion and Water Quality Modele (AD/WQ) was used to transport and spreading of salinity and BOD and DO concentrations. Model is calibrated on the basis of available experimental data. Data of another time series are used for verification of last mentioned. The comparative analysis between measured and simulated data showed that MIKE-11 is able to predict sufficiently accurate BOD and DO loads and salinity at the catchment outlet.
