Root Reinforcement: Measurement and Modelling provides important information on how to use vegetation in engineering design, including how to quantify reinforcement by both focusing on how to collect data (measurements) and how to interpret data collected to make predictions for modified soil properties (modeling). The book covers mechanical and hydrological interactions between soil and plant roots while also exploring and comparing measurement techniques and systematically dissecting predictive models developed in the last fifty years. This methodical approach and inclusion of executable code makes it a suitable resource for both researchers and practitioners, especially those new to this field.

The contribution of vegetation to slope stability is a complex, multi-scale, and multi-agent mechanism, necessitating inter-disciplinary research. Due to varying backgrounds of researchers working on this topic, standardization of methods and a systematic classification of models is lacking. This book helps to fill that void.

Gerrit Meijer is a lecturer in geotechnical engineering at the University of Bath. He has a BSc., MSc. (both Delft University of Technology) and PhD (University of Dundee, 2016) degree in Civil Engineering. With over a decade of experience with field test, laboratory tests and modelling of root-reinforced soil, he aims streamline the integration of nature-based solutions into engineering design by developing innovative measurement techniques (e.g., corkscrew testing) and practical, physics-based models (e.g., DRAM, generic fibre bundle models).

Yildiz, Anil
Anil Yildiz works as a lecturer at the chair of Methods of Model-based Development in Computational Engineering, RWTH Aachen University, Germany, and he is leading the research group Engineering Climate Change Response. He earned his BSc. and MSc. degrees in Civil Engineering at Bogazici University, and obtained his Dr. sc. in Civil Engineering from ETH Zurich in 2018. He has been awarded the Culmann Prize 2019 for an outstanding thesis on the quantification of biological effects on soil stability. His research focusses mainly on geohazards, covering a wide range of topics, such as shallow landslides, root reinforcement, soil-plant-atmosphere interactions, and methods, such as complex laboratory and field testing as well as computational and surrogate modelling.
