The University of Arizona researches how water cycles through natural and engineered environments in order to increase our understanding of how environmental systems interact and how they can be managed.
The resolution of our region and world’s many environmental challenges requires an analysis of the natural science processes driving environmental systems. To build a comprehensive understanding of these processes, University of Arizona researchers study subjects ranging from global biogeochemical cycles and pollution dynamics to the modeling of hydrologic flows and sediment transport. Experts from the fields of Plant Sciences, Agricultural and Biosystems Engineering, Ecology and Evolutionary Biology develop the environmental systems data needed by policy-makers as they make important policy and resource management decisions. Research centers unique to the University of Arizona such as the Laboratory of Tree-Ring Research and Biosphere 2 advance critical scientific knowledge and provide specialized learning opportunities for undergraduate, graduate, and professional students.

The School of Natural Resources and the Environment (SNRE) forms part of the College of Agriculture and Life Sciences and works with water on multiple levels, from measuring the hydrologic flow of a single wash, to conducting large-landscape ecosystem studies. SNRE offers both undergraduate and graduate degrees that encompass wildlife and fishers science, conservation and management, rangeland ecology, watershed management and ecohydrology, and global change ecology and management, multi-day workshops, international initiatives, community programs, and decision support tools that integrate water with other natural resources and with the communities that depend on them. In addition to the B.S., M.S. and Ph.D. in Natural Resources and the Environment, the school is the home to the M.S. in Water, Society and Policy.
The Department of Soil, Water and Environmental Science (SWES) specializes in soil, sediment, and engineered systems, and the resources that immediately surround them. There are four main areas of research: critical zone science (near-surface environments), water quality and sustainability, pollution dynamics and mitigation, and arid and semiarid agriculture. SWES also has a large and well-known extension program with strong connections to private, governmental and tribal organizations. The extension manages six projects intended as decision support tools for the public on topics such as agriculture, aquaculture, mining, weather, and climate.
The Chemical and Environmental Engineering (CHEE) mission includes developing technology in the areas of contaminant detection and remediation, environmental technology, biotechnology, and nano-scale device manufacturing in order to foster the knowledge-based economy in Arizona and the nation. Many of these technologies apply to water use and quality. Research projects in CHEE have led to developments in real-time water sensors, desalination facilities, and contaminant removal. The department also houses the SRC/Sematech Engineering Research Center for Environmentally Benign Semiconductor Manufacturing. Faculty members are active in the Superfund Research Program and algae biofuels research on campus.
The Department of Civil Engineering and Engineering Mechanics (CEEM) explores topics such as modeling hydrodynamics, sediment transport, bank erosion, alluvial channel developing processes, and water reuse, supply and distribution. Faculty teams also work on decision support models for real-world water management applications. CEEM has a student internship placement program, which can help students to work in professional environments related to water.
The School of Plant Sciences is devoted to the study of plants, how they grow, how they respond to their environment, how they evolved, how they can be manipulated, and their fungal, bacterial, and viral interactions. Plant Sciences faculty investigate the roles plants play in ecosystems and crop production, as well their uses as biofuels and biomedicinal compounds. The School of Plant Sciences contains laboratories on the main University of Arizona campus and at two field stations, the Maricopa Agricultural Research Center, and the Yuma Agricultural Center.
The Department of Ecology and Evolutionary Biology studies the nature and principles underlying ecological and evolutionary processes, the origin and maintenance of biodiversity, and the diversity and dynamics of the world’s natural systems. Its focus spans from molecular genetics and organismal function as they relate to evolution and ecology to population and community ecology, biological diversity, phylogeny, and macroevolution. Of particular water-related interest to the Department are desert habitats (especially the Sonoran Desert) and the taxonomic groups which inhabit them.
