Abstract

The objectives of this study were to evaluate the hydraulics and erosion by surface water flow of stony soil in a semiarid, rangeland environment. Methods for directly measuring rill erosion rates on undisturbed soil surfaces allowed measurements over a wide range of slopes and discharge rates. The measurements were used to evaluate flow velocity as a function of slope, discharge and rock cover, and to evaluate soil detachment rates as a function of hydraulic shear stress, stream power and hydraulic friction. Experiments were conducted at the Lucky Hills site at Walnut Gulch in southeastern Arizona
