- Abstract
- A model for the analysis of topographic
influence on shallow landslide initiation is applied
to an experimental mountain basin where high-resolution
digital elevation data are available: the
Cordon catchment (5 km2) located in northern Italy.
The model delineates those areas most prone to
shallow landsliding due to surface topographic effects
on hydrologic response. The model is composed
of two parts: a steady-state model for shallow
sub-surface runoff and an infinite-slope Coulomb
failure model which assumes that the soil is
cohesionless at failure. An inventory of landslide
scars is used to document sites of instability and to
provide a test of model performance by comparing
observed landslide locations with model predictions.
The model reproduces the observed distribution
of landslide locations in a consistent way, although
spatial variations in soil strength and transmissivity,
which are not accounted for in the model,
influence specific distribution of landslide areas
within regions of similar topographic control. (literal)
