The department offers a program leading to the Master of Science (Non-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.
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. Master's Non-Thesis study programs are individually planned to meet each student's professional objectives. Students in the Non-Thesis option are required to complete a Master's Report (professional-level paper). (They are not required to complete a research-based Master's Thesis.)
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 and coding skills, although these undergraduate units are not included in the Master's Plan of Study.
All M.S. students must complete a field methods-field synthesis course sequence: HWRS 513 A (Spring) and HWRS 513B (Summer Presession) for a total of 3 units.
To meet the professional development requirement, M.S. Non-Thesis option students are required to attend the HAS department's weekly seminar-colloquium through enrollment in HWRS 595A (1 unit) for at least one semester during academic residency. This unit is not included in the course list required for the Master's Plan of Study.
M.S. Non-Thesis option students must complete fundamental (core) courses in hydrology and water resources unless equivalent graduate courses have been taken elsewhere. Consult with the Director of Graduate Studies-Hydrology regarding potential graduate transfer course work for the Master's degree. A Master’s Final Oral Examination is required. More program information is available at the HAS department website, Master of Science in Hydrology Non-Thesis.
The Department of Hydrology and Atmospheric Sciences offers graduate-level Master of Science and Doctor of Philosophy degree programs in three Majors: Atmospheric Sciences, Hydrology, and Hydrometeorology. You can read about the differences and similarities for these majors here.

Applications for Fall Semester admission must be completed by January 15.
Applications for Spring Semester admission must be completed by August 1 (for any student requiring a visa) or October 1 (for any student not requiring a visa).
If GRE scores are close to the minimum required, we recommend you apply. Other factors in your application may help mitigate this requirement.
Required: Applicants should upload required documents to the Graduate College application, including a Statement of Research Interests; a Resume or Curriculum Vitae; Three Letters of Recommendation (instructions provided); copy of Transcripts for all colleges and universities attended; Diploma Certificates (international applicants). All of these documents may be uploaded and attached to the Graduate College online application.

Advanced elective course work (15 units total) must be approved by the Director of Graduate Studies-Hydrology. While the study of hydrology and water resources is interdisciplinary in nature, not all crosslisted courses in the catalog may be used in the Master's Plan of Study. (Crosslisted courses are those in which HWR is not the home department and the course instructors reside in other departments.) Students must complete at least 12 of 15 required units with HWRS Primary Faculty instructors. More information about required courses and pre-approved non-HWRS department courses is available in the HAS department's Master of Science Program Guide.
Potential courses include (3-unit Lecture format unless noted otherwise):
