Original Abstract
At two streams in the Czech Republic, eight dye-tracing experiments were carried out during past two years. The purpose of these experiments was to collect data sets for the calibration and verification of both analytical and numerical solution of mathematical model of advective-dispersion problem. First part of the paper deals with the preparation, accomplishment and preliminary evaluation of the experiments. Preliminary evaluation deals with the assessment of stream discharge conditions and mass balance of the dye injected. Evaluation of tracing tests by modelling techniques was performed using both one-dimensional and two-dimensional analytical and numerical stream water quality models. Within the solution, the estimate of the coefficients of transversal and longitudinal dispersion was carried out together with the estimate of the lag coefficient using inversion algorithm. Obtained values of mentioned model parameters generally correspond with values referred to in available literature sources.
