Abstract: Longitudinal dispersion coefficients in ship-canals in Northern Belgium were measured by iodide tracer experiments. A formula, proposed by Fischer, for estimating the longitudinal dispersion coefficients in rivers allows to explain the observed dispersion coefficients by reducing the value of the constant a from 0.011 to 0.0021. The smaller value can be justified theoretically. This formula can also be used for canals in which an unsteady flow takes place by considering only the continuous fraction of the flow to estimate the velocity.
