1. Kinematics and Internal Deformation of Granular Slopes
Abstract : Flow-like mass movement is the most destructive landslide and causes loss of lives and substantial property damage throughout the world every year. This thesis focuses on the spatial and temporal changes of the mass movement in terms of velocity and displacement within the failure mass, and the spatial and temporal distribution of the three dimensional internal deformation of the granular slopes using discrete element method, physical experiments, and natural landslides.

2. Landslides in the central Kenyan highlands : Risks and actors
Abstract : Measures taken to prevent and mitigate landslides are often based on geotechnical solutions. However, to understand local effects of landslides, people’s perception, knowledge and experiences are important, as this influence the level of vulnerability, and the efficacy of adaptive and mitigating measures.

3. The Use of Press Archives in the Temporal and Spatial Analysis of Rainfall-Induced Landslides in Tegucigalpa, Honduras, 1980-2005
Abstract : The scarcity of data poses a challenging obstacle for the study of natural disasters, especially in developing countries where the social vulnerability plays as important a role as the physical vulnerability. The work presented in this thesis is oriented towards the demonstration of the usefulness of press archives as a data source for the temporal and spatial analysis of landslides in Tegucigalpa, Honduras for the period between 1980 and 2005.

4. Progressive landslides in long natural slopes : potential extension and configuration of finished slides in strain-softening soils
Abstract : A finite difference method is presented for progressive slides in long natural slopes. The method is based on a strain softening material model. A detailed worked out example is given as well as examples using a spread sheet PC program and a PC program for Windows. READ MORE

5. Progressive landslides in long natural slopes : Formation, potential extension and configuration of finished slides in strain-softening soils
Abstract : After the large landslide in Tuve (Gothenburg, 1977), the author began developing a finite difference model for slope stability analysis taking the deformation-softening of soft sensitive clays into consideration. In the model, the mean down-slope deformation in each element caused by normal forces is maintained compatible with the deformation generated by shear stresses. READ MORE
