This site provides information to prospective doctoral researchers.



Only applicants with one of the following degrees from a German university or from an international university officially acknowledged by the University of Stuttgart can be accepted to the International Doctoral Program Environment Water:

  1. 'Master of Science' degree (M.Sc.) in fields related to 'Environment Water'
  2. 'Diplom-Ingenieur' degree (Dipl.-Ing.) in Civil or Environmental Engineering Sciences'

In addition, applicants with certain qualifications can be admitted into the doctoral program after a preparatory phase. This includes:

  1. Applicants with top qualifications who hold Dipl., Dipl.-Ing., or M.Sc. degrees which are not sufficiently related to the field 'Environment Water' or not from a university acknowledged by the University of Stuttgart.
  2. Candidates with M.Sc., Dipl., or Dipl.-Ing. degrees and top qualifications who have not taken undergraduate or graduate courses sufficiently related to the major subjects of the program or equivalent in quality to courses of this University. These candidates fulfil the prerequisites for the program by undertaking preparatory work including examinations. The nature and extent of this preparatory work is individually determined for each candidate by the department's examination committee. The preparatory work is required prior to admission into the doctoral program and should not exceed one year.
  3. Applicants with top qualifications from a German university of applied sciences (Fachhochschule) ('Dipl.-Ing. FH'-degrees) in fields related to 'Environment Water'. Candidates with top qualifications from German technical universities can be admitted via an evaluation procedure that assesses the individual's academic qualifications ('Eignungsfeststellungsverfahren'). In essentially all cases, preparatory work and additional examinations will be necessary to fulfil the requirements for admission to the program. The nature and extent of the preparatory work is individually determined for each candidate. Alternatively, the candidate has the option of completing one of the M.Sc.programs, e.g. WAREM or WASTE at the University of Stuttgart. For a list of all the international graduate programs at the University of Stuttgart click here.
