Shallow landslides distinguish themselves with small failure depths or equivalently small volumes (up to 2 m or 200 m3 respectively). They release on steep slopes during intense
rainfall and runout distances are usually smaller than a hundred meters. However due to their high bulk density and speed, shallow landslides represent a serious hazard to people, buildings and infrastructures such as roads or railway lines. The potential of damage is materialised through the pressure that they exert on objects during impact. The impact pressure is dependent on the kinetics and material properties of the flow as well as the geometry of the flow-object pair. Systematic study of full-scale shallow landslides was carried out at the Veltheim test site in Switzerland. Debris mixtures with volumes of 50 m3 were released down on 30° degrees steep and 40 m long slope on the hillside of a disused quarry. Mean front velocities between 5 and 11 m/s were measured, whil
