A chance constrained  model for multi-site river system is const ructed, where all the  river flow and river parameters including river temperature are  considered to be random variables. An solution method for a  general C.C . P. model, which can be applied to other problems as  weJJ, is proposed. A modification o f a method proposed by Ellis  is also made based on the proposed method. A numerical example is  provided in order to illustrate and clarify the optimization  model and its solution methods, and the proposed method is found  to provide a good solution. 0aWater quality managementxMathematical models1 aFujiwara, Okitsugu, eChairperson1 aClarke Harry R., eExamination Committee1 aYamamoto, K., eExamination Committee2 aThe Royal Government of Belgium, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
