A method to determine and apply the biomechanical properties of vegetative channel linings is presented. The method is used to protect earth channels from erosion. Using the vegetation stiffness and stem length, the deflected height of the channel lining is predicted to yield a relative roughness under given flow conditions. The relative roughness is used to calculate a value of the Darcy-Weisbach friction factor or Manning's n. A method to design a vegetative channel is included.
