Avalanches, debris, mudflows and landslides are common and natural phenomena that occur worldwide, predominantly in mountainous regions. With an emphasis on snow avalanches, this book sets out to provide a survey and discussion about the motion of avalanche-like flows from initiation to run out. An important aspect of this book is the formulation and investigation of a simple but appropriate continuum mechanical model for the realistic prediction of geophysical flows of granular material. This will help the practitioners in the field to better understand the physical input and provide them with a tool for their work. Originating from many lectures the authors have given over the years, this instructive volume brings the reader to the forefront of research - an aim also supported by an extensive bibliogrpahy of almost 500 entries. Avalanche Dynamics should be accessible to, and is intended for, a broad readership of researchers, graduate students and practitioners with backgrounds in geophysics, geology, civil and mechanical engineering, applied mathematics and continuum physics.

Nonlinearity has established itself quite well, but so far only a very small number of general nonlocal concepts and no concrete nonlocal turbulent flow solutions were available. This book presents the first analytical and numerical solutions of elementary turbulent flow problems, mainly based on a nonlocal closure.

This third volume describes continuous bodies treated as classical (Boltzmann) and spin (Cosserat) continua or fluid mixtures of such bodies.

3D creeping flows and rapid granular avalanches are treated in the context of the shallow flow approximation, and it is demonstrated that uniqueness and stability deliver a natural transition to turbulence modeling at the zero, first order closure level.

Simple, yet precise solutions to special flows are also constructed, namely Blasius boundary layer flows, matched asymptotics of the Navier-Stokes equations, global laws of steady and unsteady boundary layer flows and laminar and turbulent pipe flows.

This book delivers a thorough derivation of nonrelativistic interaction models of electromagnetic field theories with thermoelastic solids and viscous fluids, the intention being to derive unique representations for the observable field quantities.

This book describes methods of investigation for processes taking place in real lakes, as components of the geophysical environment. Covers numerical modeling, observation and experimental procedures, and the dynamics of lake water as a particle-laden fluid.

This volume examines lakes as oscillators. It covers barotropic and baroclinic waves in homogeneous and stratified lakes on the rotating Earth, presents a classification of rotating shallow-water waves and describes Kelvin-type and Poincare-type waves.

This first volume in the treatise on the Physics of Lakes deals with the formulation of the mathematical and physical background, presenting the morphology of a large number of lakes as well as the causes of their response to the driving environment.

This book puts the theory for a mixture of hypoplastic constituents on a rigorous basis using Muller and Liu's thermodynamic analysis. It addresses a continuum mechanical formulation of structured solid-fluid mixtures for elasto-viscous-frictional materials.
