Analytical modeling of canopy layer wind flow is commonly used to study local air transport around plant or building canopies. The models also help in the estimation of canopy boundary drag contribution for the atmospheric scale flow. Existing canopy layer airflow models exhibit limitations, especially for low packing density scenarios. In the current study, a new canopy layer airflow model is derived using analytical procedures for flow obstacles with different canopy roughness densities. The derivation procedure considers an assumed arbitrary relationship between the turbulent stress and canopy layer mean velocity profile, that has subsequently been verified using known boundary conditions. In addition, first-principles are combined with turbulence mixing and eddy diffusivity assumptions to obtain the analytical model for flow near obstacles of various packing densities. The new analytical model better predicts the velocity profile for a wider density range. The model also gives near ground velocity up to the accuracy of the conventional atmospheric boundary layer (ABL) model and matches the ABL conditions in the absence of canopies. The analytical model is validated through comparative assessments with experimental data extracted from literature. The analytical model is expected to help better understand flow through and/or over urban and vegetative canopies.
