"Catchment Hydrological Modelling: The Science and Art covers various methods (and equations) for modeling 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. This comprehensive guide contains questions and answers in each chapter, along with concepts and detailed equations that are fundamental to understanding CHM."--
