Please note that this an Open Access title available via Science DirectCoevolution and Prediction of Coupled Human-Water Systems provides an in-depth examination of the intricate interactions between hydrology and society. Inspired by the "Panta Rhei" scientific decade (2013-2022) of the International Association of Hydrological Sciences (IAHS), the book focuses on the interactions between hydrology and society.Authored by over 160 experts from six continents and various backgrounds in hydrology and water sustainability, the book is structured into five parts: an introduction to the complexity of human-water systems and management strategies for global water challenges, a bridge between hydrology and the environmental and social sciences through foundational concepts and methodologies, significant progress in understanding coupled human-water systems with topics such as floods, droughts, agriculture, transboundary and global human-water systems, and diverse worldwide case studies illustrating real-world dynamics and solutions for water security. The final section synthesizes key findings, making this book an essential resource for students, researchers, and practitioners focused on sustainable water management and the dynamics of human-water systems.This comprehensive volume brings the "Panta Rhei" research agenda to life by exploring the theoretical and methodological approaches to hydrological processes shaped by the relationship between the environment and humans.Presents thorough coverage of the scientific decade “Panta Rhei - Everything Flows: Change in Hydrology and Society” of the International Association of Hydrological Sciences (IAHS)Offers essential theories and techniques for understanding coupled human-water systems and the interaction of hydrology with social and environmental concernsProvides comprehensive knowledge on sustainable water management from various interdisciplinary sourcesContains in-depth case studies that illustrate real-world dynamics and provide practical solutions for achieving water security

This book focuses on how instruction affects English learners’ use of Theme and thematic progression (thematic organization).

This book explores the dynamics and vibration properties of gearboxes, with a focus on geared rotor systems. It discusses mechanical theories, finite-element based simulations, experimental measurements and vibration signal processing techniques.It introduces the vibration-resonance calculation method for the geared rotor system in wind turbines and load sharing of the planetary gear train, and offers a method for calculating the vibrations of geared rotor systems under either internal excitations from gear sets or external loads transferred from wind loads. It also defines and elaborates on parameter optimization for planetary gear systems based on the torsional dynamics of wind-turbine geared rotor systems. Moreover, it describes experimental measurements of vibrations on the wind-turbine gearbox performed on the test rig and on site, and analyzes the vibration signals of different testing points, showing them in both time and frequency domains. Lastly, it lists the gear coupling frequencies and fault characteristic frequencies from the vibrations of the gearbox housing. The technologies and results presented are valuable resources for use in dynamic design, vibration prediction and analysis of gearboxes and geared rotor systems in wind turbines as well as many other machines.
