Full Description
Root Reinforcement: Measurement and Modeling is designed to equip interdisciplinary geohazard researchers with the tools and confidence needed to effectively incorporate vegetation into engineering designs. By offering clear guidance on quantifying root reinforcement, the book emphasizes both practical measurement techniques and the interpretation of data for predicting changes in soil properties. It addresses the complexities inherent in soil-plant interactions, ensuring that readers can collect reliable data and apply modeling principles. This resource serves as a bridge for those newer to the field, promoting collaboration and fostering standardized approaches across diverse research backgrounds.
The book systematically reviews predictive models developed over the past five decades, offering executable code to facilitate hands-on application for both researchers and practitioners. The text highlights the multi-scale, multi-agent nature of vegetation's role in slope stability and underscores the need for interdisciplinary collaboration. By exposing gaps in standardization and classification, the book advocates for greater consistency in research methods, making it a valuable reference for advancing the field.
