Abstract
In the present work, an entropy based velocity profile model is proposed to de-scribe the velocity field in open channels in case of large-scale roughness. In par-ticular, the model considers the relationship between the entropy parameter and the relative submergence along with the depth where maximum flow velocity oc-curs. The proposed approach was validated by means of laboratory tests, carried out in a flume under steady flow conditions and homogeneous roughness. The comparison between the calculated velocity profiles and the observed ones seems to demonstrate the validity and reliability of the proposed methodFile in questo prodotto:
