Abstract: Abstract Sierra de Gredos, a mountain range in Central Spain, is prone to the occurrence of shallow landslides, which can transform into sediment laden flows as demonstrated by geomorphologic evidence. The analyses of these complex processes require reliable design tools for predicting thresholds of triggering precipitation in order to assess the susceptibility characteristics. In the Sierra de Gredos there is a lack of knowledge concerning how weathering mantle properties vary spatially, and what effects these spatial patterns have on infiltra...
