Shallow Geophysical Mass Flows down Arbitrary Topography

This book lays a foundation for formulating depth-averaged equations describing shallow geophysical mass flows - landslides, avalanches or debris flows. Offering detailed derivation of model equations, its stimulating examples show how the models are applied.

Geophysical mass flows, such as landslides, avalanches or debris flows, are frequent mass movement processes in mountain areas and often cause disastrous damage. This book lays a foundation for formulating the depth-averaged equations describing the shallow geophysical mass flows over non-trivial topography. It consists of the detailed derivation of the model equations. The stimulating numerical examples demonstrate how the proposed models are applied. All this make this book accessible to a wide variety of readers, especially senior undergraduate and graduate students of fluid mechanics, civil engineering, applied mathematics, engineering geology, geophysics or engineers who are responsible for hazard management.

Laying a mathematical foundation for the readers to formulate thin flows over non-trivial topography Stimulating practical examples and event back-calculations to demonstrate the applications of the models Highly beneficial to engineers and public servants who are involved in hazard mitigation projects Includes supplementary material: sn.pub/extras
