Wilfried Brutsaert (2022 Stockholm Water Prize Laureate) has revised and updated his classic textbook to take into account recent developments while retaining the rigour and structure of the previous edition to introduce the fundamental principles of hydrology. New topics include the response of the global water cycle to climate change, the land surface energy budget closure, snow melt, groundwater trends and statistical surface variability with disturbed atmospheric boundary layers. Hydrologic phenomena are dealt with at the spatial and temporal scales at which they occur in nature. The physics and mathematics necessary to describe these phenomena are introduced and developed: readers will require a working knowledge of calculus and basic fluid mechanics. This classroom-tested textbook – based on the author's long-running course at Cornell - is invaluable for entry-level courses in hydrology directed at advanced undergraduate and graduate students in physical science and engineering. In addition, it is also a great reference text for practising scientists and engineers.

Professor Wilfried Brutsaert has been active in education and research for over fifty years at Cornell University, where he has taught courses in hydrology, fluid mechanics, groundwater, and atmospheric boundary layer physics. He has been widely recognized for his research and has received many awards, including the Bowie Medal and the Horton Medal from the American Geophysical Union; the Charney Medal and Honorary Membership from the American Meteorological Society; and the International Award and Honorary Membership from the Japan Society of Hydrology and Water Resources. He was awarded a 'Doctor Honoris Causa' title at Ghent University, and he was the recipient of the Prince Sultan Bin Abdulaziz International Prize for Water. Most notably, in 2022 he was awarded the Stockholm Water Prize. He is a member of the U.S. National Academy of Engineering. Professor Brutsaert was President of the Hydrology Section of the American Geophysical Union, served as a Council member of the American Meteorological Society, and as Section Chair of the National Academy of Engineering. He is also the author of the book Evaporation into the Atmosphere (1982, Springer).
"This 2nd edition maintains the rigorous basis on mathematics and fluid mechanics, comprehensiveness, and historical accuracy, of the first. New sections cover issues of growing importance (eg climate change, spatial variability) and update the state-of-the-art (eg atmospheric rivers, the complementary relationship). The book is a substantial contribution to learners, practitioners and researchers of a rational, physically-based hydrology."
– Nelson Dias, Federal University of Parana
"The Second Edition of Hydrology: An Introduction is a masterful update to a masterful book. Created by a founding leader in the field, it is essential reading for students, instructors, and practitioners of physically-based water science and engineering."
– Laurence C. Smith, Brown University
"Wilfried Brutsaert's second edition of Hydrology: An Introduction is a classic. It is a modern and essential resource for comprehensive understanding of hydrology. This beautifully updated version transports me back to his classroom, where he eloquently and concisely helped us get to the bottom of the fundamentals of hydrology. Brutsaert elevates the subject by taking a rigorous mathematical physics approach that is refreshingly unique and original. This needs to be on the desk of any student, practitioner, or researcher who is quantifying the impacts of climate change on the hydrological cycle and regional extremes."
– Marc Parlange, President, The University of Rhode Island
"Professor Brutsaert presents a monumental and rigorous exposition of the multifaceted field of hydrology. As a master expert, he guides us though its complexity, helping us to appreciate the beauty and importance of the science of the water around us."
– Amilcare Porporato, Princeton University
"In Hydrology: An Introduction, Second Edition, the reader is rigorously, gracefully and succinctly presented with the best current understanding of quantitative descriptions of movement and storage of water on Earth. The art of Wilfried Brutsaert's treatment is his vision for how simple, broadly applicable, and accurate predictions of hydrological responses can be obtained from basic scientific principles when viewed from deep understanding. The text is informed by a commanding understanding of the literature not as an endpoint, but rather a living foundation upon which continued advancement of why and how water moves can grow. This up-to-date textbook provides a unique resource for students and practitioners because it places all of the central results in the framework of their conceptual origins. Hydrology: An Introduction is an essential textbook for the office of any person seeking to make predictions where, when, and how much water will occur on Earth."
– John Selker, Distinguished Professor of Ecological and Biological Engineering, Oregon State University; President Elect of the Hydrology Section of the American Geophysical Union
"Brutsaert's second edition of Hydrology represents a tour de force in its scope and depth of analysis of the critical components of the terrestrial water system. The second edition addresses issues of climate change impacts on the water cycle, a critical topic for hydrologists yet rarely considered at the time of the first edition, and also introduces new advances in observation and measurement particularly in hydrometeorology. The 'two format' system continues to provide an outstanding textbook for the advanced undergraduate/graduate level while at the same time provides a valuable desk reference for the rest of us!"
– Scott Tyler, University of Nevada, Reno
"The second edition of Wilf Brutsaert's book has an imposing wealth of information on the foundations of hydrologic science, based on first principles. The enterprising graduate student (or exceptional undergraduate) who makes the effort to work through the text beginning to end will assuredly have a sound grasp of the underpinnings of the field."
