Part I: Introduction
1. Introduction Relevance and a brief history of research on root reinforcement, structure of the book, access to online supplementary material, e.g. code snippets, Python packages.
2. An overview of soil mechanics Important concepts in soil mechanics, i.e. stress, displacement, strength, and flow.
3. Soil-root interaction Physical mechanisms of soil-root interaction at individual roots, root-soil bonding, root-soil composite will be explained. This key chapter will form how the next parts are organized.
Part II: Measurement
4. Individual roots Tests and measurements conducted on individual roots or groups of roots. Root tensile tests, bending tests, biotic parameters.
5. Root-soil bonding Experiments, under laboratory or field conditions, to determine the strength of the root-soil bonding. Slippage and breakage mechanisms.
6. Root-soil composite Experiments, under laboratory or field conditions, to determine the strength of the root-soil composite, e.g. direct shear, triaxial, centrifuge testing, as well as tests and monitoring of hydrological regime of root-permeated soils.
Part III: Modelling
7. Individual roots Biomechanics, variability, multi-tissue models, single root in direct shear, bending reinforcement.
8. Root-soil bonding Root pull-out, transverse loading.
9. Root-soil composite – hydrological models Permeability, infiltration, soil water retention, root water uptake, soil suction.
10. Root-soil composite – analytical mechanical models Fibre bundle models, Root bundle models, Dundee root anaytical model.
11. Root-soil composite – constitutive models Phase relationships, single constitutive models for rooted soil, composite models, coupling.
12. Root system Root distributions with depth, root distributions with distance to plant stem.
13. Slope stability Infinite slope, Bishop circles, limit state analysis, SOSlope, finite element analysis.
14. Catchment Large-scale landslide risk assessment, TRIGRS, SlideforMap.
