The department offers a program leading to the Master of Science (M.S. Thesis option) degree with a major in hydrology. The faculty offers competence in hydrogeology, hydrogeochemistry, hydrometeorology, hydroclimatology, environmental hydrology, ground-water hydrology, surface-water hydrology, vadose zone hydrology, mathematical and statistical methods in hydrology (including stochastic and numerical modeling), water resources systems, and water resources policy.<br>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. More information about faculty research areas of expertise may be found at the department website, Research Focus Areas.<br>M.S. Thesis option 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.<br>Time-to-completion for the Master of Science degree in Hydrology and Water Resources is approximately 2 years (coursework and research) for well-prepared students. All Thesis Option candidates must submit a Thesis or manuscript which has been judged by the student's committee to be eligible for publication in an appropriate scientific journal and present the results at a national or international scientific meeting. See the Master's Thesis Manuscript Options for details about Traditional and Publication formats. All Non-Thesis Option candidates must complete one additional 3-unit course in the department and a 1-unit Report which has been judged by the student's examining committee to be a professional-level report.
