ABSTRACT: This paper presents a first attempt of reviewing the methods developed to define landslide failure surfaces and volumes based on surface information. It reminds the simplest models such as the volume estimation using ellipsoids and the information that can be obtained from surface displacement and morphology. A method to define the volume of rockslide is also presented. Finally the new development related sloping local base level (SLBL), which allows based on a digital elevation model (DEM) to obtain a possible failure surface automatically, are presented. The perspectives are drawn and uncertainty is partially addressed.
RÉSUMÉ: Cet article présente une première tentative de revue des méthodes dédiées à la caractérisation des surfaces de rupture et des volumes des mouvements de versants. Ces méthodes se basent sur des données de surface. On rappelle les modèles les plus simples tels que l'estimation de volumes à l'aide des ellipsoïdes et les informations que l'on peut obtenir à partir de dérocheux est également présentée. Enfin, les nouveaux développements liés au sloping local base level (SLBL), qui terrain, une possible surface de rupture automatiquement, sont présentés. Les perspectives liées à ces méthodes sont abordées et le problème de l'incertitude est partiellement abordé.
