AbstractIn the recent years, gully erosion attracted increasing attention from scientists. However, there were few studies on the soil erodibility/anti- erodibilty for the gully erosion. Based on the principle ofgeotechnical slaking test, a new set of test apparatus had been designed and applied on the study oferodibility of soil at the gully head. In this experiment, 6 typical gully heads had been chosen. Soil at thedifferent depth of each gully head had been sampled by the foil sampler and tested the slaking rate ofthem. Moreover, shear strength of soil at different depth of each gully head had been tested in situ. Theresults showed that gullies developed on the stratified soil or homogeneous soil have different morphological characteristics. At the sharp gully head, the erodibility of underlying soil was lower thanthe overlying soil's. Contrarily, at gradual gully head, the erodibility of underlying soil was not lower thanthe overlying soil's. Moreover, slaking rate of most gullies' soil in the study area is an inverse proportion tothe shear stress. Thus, slaking rate and in-situ shear stress, any of them can be the indicator of theerodibility of soil in the study region. But shear stress is easier to measure in situ.
