Thomas Zieher and his colleagues have published new results from their work on shallow landsliding in the Journal of Hydrology. Physically-based dynamic modelling of shallow landslide susceptibility rests on several assumptions and simplifications. However, the applicability of physically-based models is only rarely tested in the field at the appropriate scale. This paper presents results of a spray irrigation experiment conducted on a plot of 100 m² on an Alpine slope susceptible to shallow landsliding. [ link ]
