Abstract: Based on probabilistic assessment of the consistency of piezometer water level increments and decrements, a piezometer membership function of a fuzzy set is introduced. By investigating the membership of the Tresna water reservoir piezometers in a fuzzy set, the watertightness of the seepage curtain was assessed, and, following the maximum degree of membership from headwater to tailwater, a seepage path through the left abutment of the Dobczyce dam was determined.
