In this manuscript we focus on the study of flow structures in a channel partially obstructed by an array of equispaced, vertical, rigid, emergent, circular steel cylinders. Emergent vegetation strongly affects the flow hydrodynamic structures, forming a transversal abrupt velocitytransition region at the interface between the obstructed and the unobstructed domains. A modified log-law predicting the representative transversal profile of the mean flow velocity at the obstructedunobstructed interface is proposed and validated.

Abstract

In this manuscript we focus on the study of flow structures in a channel partially obstructed by an array of equispaced, vertical, rigid, emergent, circular steel cylinders. Emergent vegetation strongly affects the flow hydrodynamic structures, forming a transversal abrupt velocitytransition region at the interface between the obstructed and the unobstructed domains. A modified log-law predicting the representative transversal profile of the mean flow velocity at the obstructedunobstructed interface is proposed and validated.
