A one-equation-type subgrid-scale (SGS) model was proposed in order to enable the large eddy simulation (LES) of plant canopy flows. The SGS kinetic energy equation was derived from the equations of continuity and Navier-Stokes. This equation was closed by modeling the unknown terms according to the physical meaning of each term in the equation. The wake production term in the SGS kinetic equation could be derived analytically. However, the wake dissipation term did not appear when the SGS kinetic energy equation was derived from the basic equations.
