Overview

abstract

• This work presents the validation of a two-layer mixing-length model for turbulence applied to shallow water flows in presence of vegetation. In order to determine the vertical velocity variations when submerged vegetation exists, a multilayer numerical model-based approach is used. A second-order finite difference method is used for spatial discretization and a semi-implicit lagrangian– eulerian method is used for time discretization. The comparisons to experimental data for validating the turbulence model show good agreement for two cases, a channel with submerged vegetation and other one with both submerged and emergent vegetation. © Springer-Verlag Berlin Heidelberg 2013.
