Environmental Sciences Major: Hydrology Option B.S.


What is the hydrology option in Earth sciences?

This intercollege program, hosted between the colleges of Engineering & Physical Sciences and Life Sciences & Agriculture, is designed for students seeking broad, interdisciplinary training in the foundational sciences with an emphasis on the interactions of biological, chemical and physical processes shaping our natural environment. The hydrology option, coordinated by the Department of Earth Sciences, provides students with foundational coursework in math and the sciences, paired with broad training across the environmental sciences and specialized training in water resources and hydrologic processes, positioning students with the ability to focus on water resource issues of national and international concern.

Why study hydrology at UNH?

The location of UNH, on the Great Bay Estuary and close to the White Mountains, provides an ideal backdrop for hands-on learning opportunities for all environmental science students. Students have multiple opportunities to immerse themselves in research experiences in the field and in state-of-the-art laboratories, and funds are available by competitive application to support these opportunities. Employment for environmental scientists is projected to grow 11 percent from 2016 to 2026, faster than the average for all occupations. The increasing need for environmental protection and responsible land and water resource management is projected to spur demand for environmental scientists.

Curriculum & Requirements

The College of Engineering and Physical Sciences (CEPS) and the College of Life Science and Agriculture (COLSA) jointly offer a bachelor of science degree in environmental sciences. Environmental sciences, an interdisciplinary field, focuses on the interaction of biological, chemical, and physical processes that shape our natural environment. Students graduating with a degree in environmental sciences will have an understanding of these interacting processes, the ability to communicate effectively with both scientific and lay audiences, competency in field methods appropriate for entry-level environmental science positions, competency in the use and application of Geographic Information Systems (GIS), a basic understanding of environmental policy, and the ability to contribute to multidisciplinary teams. The University of New Hampshire is a recognized leader in environmental sciences research, and the environmental sciences program capitalizes on faculty expertise in this area. The full-time faculty members comprising this program have major teaching and research emphases in the areas of biogeochemical cycling, environmental chemistry, geospatial science, ecosystem science, global change, hydrology, plant ecology, soil science, and water resource management. 

Employment opportunities include: environmental consulting firms, educational facilities (e.g., science centers), environmental monitoring laboratories (e.g., water treatment plants; the Environmental Protection Agency), government agencies (e.g., the U.S. Geological Survey, Bureau of Land Management, Natural Resource Conservation Service), university and government research laboratories, and nongovernment environmental organizations. The environmental sciences program also constitutes an excellent preparation for graduate programs in several areas relating to the environment. Students should consult with their adviser early if their goals include further study.

The Program has four options, and specific course requirements for the major vary by option. The geosystems and hydrology options are both managed by the Department of Earth Sciences in CEPS, and the ecosystems and soils and watersheds options are both managed by the Department of Natural Resources and the Environment in the COLSA. The hydrology option provides students with a solid grounding in fundamental hydrological principles and quantitative reasoning.

In addition to the Discovery Program and University writing requirements, all students will take Introduction to Environmental Science NR 403 Introduction to Environmental Science and Professional Perspectives in Natural Resources (NR 400 Professional Perspectives in Natural Resources), plus one other elective introductory environmental science course. Foundation courses include introductions to biology, physics, chemistry, geology, calculus, and statistics.
