%X abstract the methodology for the modelling of three parameters that characterize water quality: biochemical oxygen demand, dissolved oxygen and ammonium in a luyan¨® river stretch using the riosep £¿ v.2.0 software. the procedure combined the use of radiotracer techniques for estimating the hydrodynamic parameters of the stream with physicochemical techniques to determine its basic parameters. the survey of hydrodynamic parameters in the stream was conducted with the use of as a radiotracer. simultaneously with flow determination, water was sampled at five stations in the main channel and two tributaries, in order to determine the physical and chemical parameters of interest. the result was a model that describes accurately the biochemical oxygen demand and dissolved oxygen behaviour (more than 90%), and showed a good result for ammonium, so it adequately characterizes the purification and oxygen balance processes in water.
