Risk factor in tunnelling projects is so important. This factor can be effect on at least one project objective such as time, financial, and quality. So, this factor is critical for managers or planners, so that; they always look for an appropriate method in order to prioritize the existing risks. There are miscellaneous techniques for evaluating and ranking risks such as Delphi technique, multi criteria decision making (MCDM) methods, and fuzzy logic. The MCDM methods are suitable tools to solve sophisticated problems in real world. TOPSIS approach is one of the most application MCDM methods. On the other hand, fuzzy logic is a helpful tool in the presence of uncertainty and complexity. In this paper, we applied TOPSIS approach under fuzzy environment in order to evaluate the existing risk in water transfer tunnel project of Dashte Zahhab. The results demonstrate collapse is the riskiest parameter.
