The MWR degree is obtained by following one of two tracks or options: the Hydroscience track or the Policy/Management track. Each track consists of 39 semester credits: 36 credits of coursework plus 3 credits for a professional project. The Hydroscience track is designed primarily for students with technical backgrounds (biology, chemistry, earth/environmental sciences, mathematics, toxicology, physics, physical geography, engineering, etc.) who wish to complement their primary discipline by obtaining expertise in water resources with an emphasis on the scientific/engineering aspects of water. Students without technical backgrounds may select this track but may need to take remedial hydroscience classes to prepare for graduate level course work. The Policy/Management track is designed for students with diverse backgrounds—the natural sciences, political science, economics, sociology, management, engineering, geography, psychology, public administration, law, community and regional planning, public health, etc.—who wish to emphasize those aspects of water dealing with economics, policy, administration, management and planning. The curriculum for each track is flexible, enabling a student, with guidance from his/her advisor and committee, to design a course of study in accord with his/her career objectives.
