Has anyone modeled Large wood (or other flow deflection) structures in a 2D area? I am considering modeling them as a structure with a very high roughness value for the cell or possibly adding them directly into the terrain. Any input or suggestions would be greatly appreciated.
Thanks ahead of time!
Either method would work. You will still get a larger than actual volume stored in the high n-value method. Be aware that RAS will only assign one n value per cell face so you need to define your mesh or n value accordingly. RAS is taking which ever n value makes up the largest % of the cell face length as the value it assigns.
