Cases and Materials on Water Law, steeped in water history, honors its distinguished author lineage by maintaining the book's longstanding tradition of focused instruction on property rights in water, covering appropriative and riparian principles, groundwater, interstate allocation, and federal-state relations. The Tenth Edition integrates these principles into today's regulatory framework, addressing the need for sustainable management and increased protection of the environment and public rights. The new edition is reorganized to prioritize student learning, with fewer and more focused notes and several new principal cases.
