Abstract:

A number of methods for longitudinal dispersion coefficient computation of natural rivers based on tracer tests were evaluated. It was found that the change-of-moment method is inaccurate and the routing method is also questionable. A modified method using non-linear approach procedure was proposed for longitudinal dispersion coefficient calculation.
