The obtained results demonstrated that the proposed model allowed for reasonably predicting the amount of soil particle removal and understanding erosion characteristics of soils through the HET.Īrulanandan K, Perry EB (1983) Erosion in relation to filter design criteria in earth dams. A series of HETs were performed under different flow rate to verify the proposed model. The analytical equation could be applied to determine soil particle removal, radial erosion propagation, erosion coefficient, and critical shear stress. An analytical equation was deduced from a physically based model incorporating Bernoulli’s principle and erosion constitutive law for internal erosion within a soil pipe driven by pressure gradient. The aim of this study is to propose a simple model based on Bernoulli’s principle to interpret erosion characteristics of geomaterials in HETs. It is noted that there are not many studies that focus on the development of a theoretical model describing the erosion characteristics and the associated process of soil particle detachment in HETs. Hole erosion test (HET) is a simple and effective approach to determine erosion characteristics. ![]() The erosion characteristics indicate soil particle removal in term of internal erosion that might occur in earthen structures. Determination of erosion characteristics is of great significance to assess the erodibility of geomaterials that are subjected to seepage force.
