Entropy velocity distribution in a river

In the paper the results of the extension of the entropy velocity distribution to a data set collected in field and relative to a natural rivers are presented. The analysis represent the first attempt to use the entropy model to describe the natural flow assessment. Further, the velocity distribution along the vertical has been explained employing the entropy model at the local scale and calibrating the entropy parameter through the average and maximum velocity observed per each vertical. That is, a scaling approach of the entropy profile is proposed and the comparison between the classical formulation and the scaled one is reported in terms of average absolute and global errors observed.
