Longitudinal Dispersion Coefficient in Natural Streams
The paper deals with the estimation of the longitudinal dispersion coefficients of accidental pollution in the small
natural streams. The paper briefly reviewed the theoretical background and the results of field experiments needed to determine the longitudinal dispersion coefficient. The values of the coefficients can influence the outcome of the calculations or simulations of leaking substances into the flow. Therefore, accurate determination of the values of these coefficients (also on the basis of field measurements) is an important part in solving the problems of pollution transport in the stream. In this study, we summarized the results of our field experiments in the various Slovak streams on identifying the coefficient of longitudinal dispersion.
Key words: Dispersion coefficients, water quality modeling.
