چکیده انگلیسی
A field tracer experiment using radioisotope 82Br was performed to estimate the dispersion characteristics of pollutants in river environment. The dispersion coefficients in the longitudinal and transverse directions were determined by using the measured concentration of a radioisotope. Numerical models were applied to calculate the flow and concentration fields at the experimental site. Several numerical simulations were performed to investigate the effects of the numerical results according to variations of the dispersion coefficients. The calculated results for several runs were compared with the measured ones by using statistical methods. The calculated concentrations agreed well with the measured ones.
