摘要

A new expression for the prediction of longitudinal dispersion coefﬁcient in natural rivers, usingngenetic algorithms, is proposed. The expression uses hydraulic and geometric characteristicsnof rivers, which are readily available. For performance evaluation, using published ﬁeld data,nresults of coefﬁcient prediction by the new expression and by the other reported expressions arencompared. According to various performance indices, it is concluded that the new formula predictsnthe longitudinal dispersion coefﬁcient more accurately. Sensitive analysis performed on inputnparameters indicates the ratio of the cross-sectional mean velocity to the bottom shear velocity tonbe the most inﬂuencing parameter for accurate prediction of the longitudinal dispersion coefﬁcient.
