Introduction to Quantitative Hydrology

This textbook serves as an introductory quantitative course on the fundamental elements of the hydraulic cycle. It enhances students' understanding by discussing the latest advancements in hydrological science, covering both experimental and computational techniques. This textbook is self-contained, requiring no prior knowledge, and includes numerous illustrations to clarify scientific concepts. Complex mathematical treatments are minimized, focusing on clear, step-by-step examples and guides that utilize scientific calculators and spreadsheets. Where appropriate, chapters include assignments that reinforce the textbook’s role in academic settings. A virtual laboratory section is also provided, featuring experiments and example datasets for student analysis. Additionally, the text outlines the equipment needed to set up a physical laboratory, making it practical for educators to implement. Targeted at first-year college students, this book supports early career exploration in fields such as natural resources, earth sciences, and civil and environmental engineering. Offering this course early allows students to make informed decisions about their academic and career paths before they reach their senior year, providing them with ample time to pursue specialized interests.

About the Author :
Aly I. El-Kadi earned his Ph.D. in Groundwater Hydrology from Cornell University’s School of Civil and Environmental Engineering in Ithaca, New York. He currently serves as Professor Emeritus in the Earth Sciences Department and the Water Resources Research Center (WRRC) at the University of Hawaii (UH). His teaching and academic focus were on hydrology and groundwater modeling. His research addressed critical areas such as the impact of climate change on water resource sustainability, numerical modeling of groundwater systems, and the simulation of multiphase flow and hydrocarbon transport. His work addressed the growing pressure on Hawaii’s coastal aquifers due to population growth, economic development, and climate change. He also contributed to research in American Samoa and Jeju Island, Korea. He is the author or co-author of approximately 170 publications, including two edited books. His career highlights include serving as the Associate Director at WRRC, which focuses on water resource challenges in Hawaii, American Samoa, and other Pacific islands.
