Landslides represent one of the most destructive natural catastrophes.
They can reach extremely long distances and velocities, and are capable
of wiping out human communities and settlements. Yet landslides have a
creative facet as they contribute to the modification of the landscape.
They are the consequence of the gravity pull jointly with the tectonic
disturbance of our living planet.
Landslides are most often studied within a geotechnical and
geomorphological perspective. Engineering calculations are traditionally
applied to the stability of terrains. In this book, landslides are
viewed as a physical phenomenon. A physical understanding of landslides
is a basis for modeling and mitigation and for understanding their flow
behavior and dynamics. We still know relatively little about many
aspects of landslide physics. It is only recently that the field of
landslide dynamics is approaching a more mature stage. This is testified
by the release of modelling tools for the simulation of landslides and
debris flows. In this book the emphasis is placed on the problems at the
frontier of landslide research. Each chapter is self-consistent, with
questions and arguments introduced from the beginning.
