Abstract
Information on surface shear stress for a given flow condition is necessary to quantify potential soil erosion. As water moves across a rough surface, part of the total force acts on the surface roughness and the remainder acts on the intervening soil surface. Vegetation acts to reduce surface shear stresses, thereby reducing erosion. Information on the drag force acting on individual vegetative elements is necessary for partitioning shear stress between the vegetation and the soil surface. A technique developed to measure the drag force on individual vegetative elements is presented. Vegetation elements are modeled in a hydraulic flume using circular cylinders and idealized shapes to account for variations in frontal area (both increasing and decreasing) with height. A range of flow depths and velocities is used to simulate overland flow conditions.
