  abstract =     "The longitudinal dispersion coefficient (k) is
                 necessary for a plethora of mass transport applications
                 in fluids, but a general formulation for k remains
                 lacking. In this study, we propose a canonical form for
                 k that reflects the physics of dispersion and suits
                 complex flow conditions encountered in natural streams.
                 This general form is much more concise than previous
                 predictors. A predictor for k of natural streams is
                 also obtained using a genetic programming(GP) without
                 pre-specified correlations among field data or a
                 pre-specified form of the predictor. This predictor is
                 physically sound (i.e. exhibits the aforementioned
                 canonical form) and appears to be commensurate to or
                 better than previous estimates of k. A grey model,
                 which measures the proximity of data to a target shape
                 (i.e. the proposed physically sound form), is also used
                 to verify that the canonical form is appropriate. A
                 formulation for k in natural rivers is obtained by
                 utilising a GP. Its form is consistent with the
                 canonical form.",
