This paper reviews the commonly available models used to model landslides. The main purpose is then to examine some of the wider issues associated with the developments that are required if we are to develop 3-D applications and to extrapolate
their use to long time scales. The paper does not discuss landslide hazard mapping models but concentrates on the 3-D and temporal problems associated with the modelling of single slides.

This paper offers a method for assessing climate change impacts on landslide frequency based on general circulation models (GCM). GCM results are downscaled with an empirical-statistical technique to derive local precipitation scenarios
. These scenarios are used as input to a simple slope hydrological and stability model. A case study of a small landside in South East France, Barcelonnette Basin, is presented and discussed.

Within the framework of Geographic Information System (GIS), the distributed three-dimensional groundwater model MODFLOW is applied to evaluate the groundwater processes of the hydrogeological system in the Alverà landslide. The application
of this model has permitted an analysis of the spatial distribution of the structure (DTM and landslide bottom) and the mass transfer elements of the hydrogeological system. The field survey suggested zoning the area on the basis of the recharge, groundwater

The purpose of this paper is to describe the geotechnical investigations carried out on a mudslide in the area of Cortina d'Ampezzo (Dolomites, Italy) in the framework of the TESLEC Project. On the basis of collected data, a dynamic stability model
was developed in order to determine the relationships between piezometric fluctuations and velocity variations. The model was first applied to the most superficial landslide which, owing to its geometrical characteristics, may be considered as an infinite slope.

with a conceptual model aimed at describing the relationships between the mass-movements on the slope and the construction/destruction stages of the fan at the base of the slope. The model is based on the assumption that the process is cyclic and self-regulating.
The aims of this paper are : to establish the features and the spatial distribution of landslides in the coastal Asturian valley of the Meredal River; to build a chronological model of the temporal sequences of landslides; to set up the causes
and fluvial features. 10 landslide classes were thus identified and their chronological limits defined on the basis of 19 C 14 age determinations on fluvial and glacial deposits. The chronological classes identified were compared with existing climate models
