As hydrology is now approached from environmental and social perspectives�in addition to the more traditional physical geography and civil engineering perspectives�there has never been a more opportune time to develop a sound understanding of the field.

Introduction to Physical Hydrology provides students with a solid foundation in the core principles of the subject. Exploring the key rules that govern the flow of water on land, it considers the four major types of water: atmospheric, ground, soil, and surface. The text offers insights into major hydrological processes and shows how the principles of physical hydrology inform our understanding of climate and global hydrology. The book includes a carefully developed and class-tested pedagogical framework: it employs an extensive range of exercises, global examples, and a series of Math Toolboxes to help students engage with and master the material. A Companion Website features resources for students and instructors.
