Through application of the Smoothed Particle Hydrodynamics (SPH) method this monograph mainly
focuses on large deformations and flow failure simulations of geomaterials and movement
behavior which are always involved in geo-disasters. The work covers the theoretical
background numerical techniques code implementation issues and many novel and interesting
applications. Two-dimensional and three-dimensional SPH models in the framework of both
hydrodynamics and solid mechanics are established with detailed descriptions. The monograph
also contains many appealing and practical examples of geo-disaster modeling and analysis
including the fluidized movement of flow-like landslides lateral spread of liquefied soils
and flow slides in landfills. In the documented SPH simulations the propagation of
geo-disasters is effectively reproduced. Dynamic behaviors of geomaterials during propagation
are ascertained including sliding path flow velocity maximum distance reached and
distribution of deposits. In this way the monograph presents a means for mapping hazardous
areas estimating hazard intensity and identifying and designing appropriate protective
measures.
