Catchment Hydrological Modelling: The Science and Art enables the reader to comprehend theory and approaches that catchment hydrological models (CHM) are based upon, and provides various methods (and equations) for modelling all components of a CHM. Readers are presented with multiple methods and approaches to modeling the same component, allowing them to distinguish the differences between methods. The books also provides a clear understanding of what makes some commonly used hydrological models similar or different and what their strengths and weaknesses may be.Catchment Hydrological Modelling: The Science and Art is a comprehensive guide with questions and answers included for each chapter, concepts and equations that are fundamental to understanding CHM, and additional information and detailed equations at the end of every chapter. This book is useful to students and professionals in the fields of catchment and hydrology, as well as environmental and civil engineers.
