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 method
