Short summary

Regional frequency analysis gives a quantity for the design of hydaulic structures. The stationarity of record shuld be assumed for its application. Climate change and anthropogenic factors can, however, violate this assumption. Nonstatonary regioanl frequency analysis, therefore, is required. There can be four types of index flood models as a representative technique for nonstationary regional frequency analysis. This research focused on the evaluation of their perfomances.
