The programs are designed for students with interests in the physical, chemical, and biological aspects of the hydrologic cycle, as well as water resources systems, environmental studies, or water policy and the social sciences related to water resources. Students may concentrate in one or a combination of these fields but should acquire some proficiency in all aspects of hydrology and water resources. Research-based M.S. study programs are individually planned to meet the student's special interests and professional objectives.

M.S. applicants need not have completed an undergraduate degree in hydrology and water resources; however, previous study in this field or a related field is beneficial. The programs have been designed to enable students who have completed fundamental undergraduate mathematics and science course work to enter directly.

All M.S. students are expected to acquire basic computer programming skills and complete a field methods course. To meet the professional development requirement, M.S. students are required to attend departmental seminars and colloquia at the beginning of academic residency and to enroll in one advanced seminar course (696-series) at or near the end of their academic residency.

Each M.S. student must complete fundamental, or core, courses in hydrology and water resources unless equivalent graduate courses have been taken elsewhere. A Master's Thesis is required; the Master's Thesis Publication option is also available. A Master’s Final Oral Examination is required.
