The modelling of pollution transport processes in open channels requires good knowledge about parameters such as hydrodynamic dispersion, advection and decay rates. Such parameters can be determined by dye tests. Number of tracer studies have been done on large rivers. In this study the dye test was realized on the local small stream using Rhodamine WT fluorescein dye as a tracer. Four tests were carried out in order to obtain longitudinal and transversal dispersion. For this purpose, analytical solution of transport dispersion equation was used. The results indicated dispersion coefficients DL = 0.065 m2/s (longitudinal) and DPH = 0.0006 m2/s (horizontal transversal).
