Abstract This study reviewed the Weiss model, probably the only theoretical study available on the fixed- to true-interval rainfall conversion factor (CF), and implemented to propose a modified Weiss model. Also, the characteristics of the temporal distribution of rainfall were considered in the estimation of CF to overcome the problem of these two models, whose results were compared with those estimated empirically. As results, the CF was found to be differently estimated depending on the temporal distribution of rainfall. Especially, the theoretical CF estimate for the center-concentrated rainfall distribution was found to be very similar to that of empirical results of domestic and foreign studies.
