Résumé :	Erosion is one of the main causes of instabilities within hydraulic earth structures. Two types of erosion can be distinguished: suffusion and interface erosion. This paper deals with the interface erosion phenomenon and the Jet Erosion Test is used in order to evaluate the erodibility of fine soils. A new energy analysis of the test is developed, relating the total eroded mass to the dissipated fluid energy. A new erosion resistance index is proposed. The erodibility is evaluated for twelve natural soil specimens which are compacted with the Proctor protocol. They represent a large range of erosion sensitivity. A wide dissipated hydraulic energy scale appears and a statistical analysis is carried out which gives a correlation of the erosion resistance index with three physical parameters.
