Storm-triggered Landslides in Warmer Climates

This volume discusses the general physics of debris flows and various approaches to modeling - including the SEGMENT-Landslide approach as well as the pros and cons of these approaches and how other approaches are sub-sets of the SEGMENT-Landslide approach. In addition, this volume will systematically unify the concepts of vadose zone hydrology and geotechnical engineering, with special emphasis on quantifying ecosystem consequences of storm-triggered landslides in a warmer climate setting. The reader will find a comprehensive coverage of concepts ranging from hillslope hydrology, porous granular material rheology and the fundamentals of soil properties, to state-of-the-art concepts of enhanced hydrological cycle with climate warming and a discussion of new approaches for future research.

Addresses the mechanical, as well as ecological system consequences of storm-triggered landslides, with a state-of-the-science model as the basis Discusses the consequences of a warming climate including uplifting of atmospheric mass center and altered circulation, non-uniform warming of the major ocean basins and effects on the walker circulation and atmospheric rivers Explains in detail the mechanical, chemical and hydrological effects of vegetation root systems Covers societal impacts and proposes an intelligence network for dealing with mudslides Explores the likely impact of sea level rise due to ice sheet disintegration Includes supplementary material: sn.pub/extras

Autorentext
Dr. Ren's main interests lie in climate diagnostics, dynamic data assimilation and fluid mechanics, as well as land surface modeling of ecosystem responses to a warming climate, glacier/ice sheet dynamic modeling, natural hazards such as storm-triggered landslides, frozen soil thawing and refreezing processes and soil nutrient fluctuations. He has coded a scalable, extensible and adaptable geo-fluid model (SEGMENT), which offers a unified approach for a disparate set of poorly understood phenomena in geophysical flows/movements such as glacier sudden surge and which is also is capable of describing nutrient content between different vegetation types.
