A scientifically rigorous text grounded in socioeconomic reality that examines both physical hydrology and contemporary water usage issues. Integrating the underlying science of hydrology with real-world usage scenarios, Water Resources offers a modern treatment of water resource management, covering rivers, lakes, groundwater, soil water, connections between water quantity and quality, economic and legal constraints, impacts of climate change and population growth, and proposed paths forward for sustainable water use. The book includes quantitative calculations, qualitative think-pieces, case studies, and an appendix on units and conversions.
