Hydrological Modelling of Slope Stability

Abstract:  Extreme rainfall events are the major driver of landslide occurrences in mountainous and steep terrain regions around the world. Subsurface hydrology has a dominant role on the initiation of rainfall-induced landslides, since changes in the soil water content affect significantly the soil shear strength. Rainfall infiltration produces an increase of soil water potential, which is followed by a rapid drop in apparent cohesion.

An Object-oriented computational framework for the simulation of variably saturated flow in soils, using a reduced complexity model

Abstract: A simple and efficient computational modelling framework is presented for the simulation of variably saturated flows in porous media, which is not based on a conventional numerical solution of the Richards’ equation. The computational domain is discretised with a regular grid and simple rules govern the flow dynamics.

Geophysical imaging of shallow subsurface topography and its implication for shallow landslide susceptibility in the Urseren Valley, Switzerland

Abstract: Landslides and soil erosion are an ever present threat to water management, building construction, vegetation formation and biodiversity in the Swiss Alps. Improved understanding of the mechanics and causative factors of soil erosion is a key factor in mitigation of damage to Alpine natural resources. Read more

A comparison of local and aggregated climate model outputs with observed data

Abstract: We compare the output of various climate models to temperature and precipitation observations at 55 points around the globe. We also spatially aggregate model output and observations over the contiguous USA using data from 70 stations, and we perform comparison at several temporal scales, including a climatic (30-year) scale.
