  abstract =     "Genetic Programming has been used to determine Chezy
                 resistance coefficient for full circular corrugated
                 channels. Three corrugated plastic pipes have been
                 experimentally studied in order to generate data. The
                 tests aim at measuring hydraulic parameters of the
                 open-channel flow for some slopes, from
                 3.49-17.37percent (2-10), in order to discover the
                 dependence of the channel resistance coefficient when
                 wake-interference flow occurs. The monomial formula for
                 the Chezy resistance coefficient performs well on
                 experimental data, both from measurement errors and
                 from a technical point of view. In this paper, we
                 present some very parsimonious formulae that have been
                 created by Genetic Programming with few constants and
                 which fit the data better than the monomial formula.
                 Moreover, two of the Genetic Programming formulae,
                 after 'physical post-refinement', seem to better
                 explain the role of the roughness in the Chezy
                 resistance coefficient for corrugated channels with
                 respect to its traditional expression for rough
                 channels. This fact suggests that at least the
                 structure of those formulae can be extrapolated to
                 other types of corrugated channels. Finally, the work
                 stresses the fact that the Genetic Programming
                 hypothesis can be easily manipulated by means of
                 'human' physical insight. Therefore, Genetic
                 Programming should be considered more than a simple
                 data-driven technique, especially when it is used to
                 perform scientific discovery.",
