At the Civil Engineering Faculty Subotica, PhD studies within the Civil Engineering Program offer a number of elective courses that allow candidates to choose an area of study. A student may choose from structural and materials engineering or hydraulic, water resources and environmental engineering, or a combination of the two areas of expertise. In the case that the candidate chooses to study hydraulic, water resources and environmental engineering, the recommended courses are: mathematical courses, a course on the principles of measurements; courses on viscous flow, turbulent flows, and catchments processes; a group of experimental courses; a group of theoretical-numerical courses; a sedimentation processes course and a wastewater treatment course.
