Abstract: In order to explore the characteristics of precipitation extremes in the Three Gorges Reservoir Intervening Basin (TGRIB), based on the daily precipitation data (18 rain gauge stations) in the TGRIB during 1961-2020, seven extreme precipitation indices were firstly selected in this paper to investigate the tempo-spatial variations of extreme precipitation in the TGRIB. Two extreme precipitation series were then filtered from the 60 years of precipitation data at 18 stations using the annual maximum (AM) and peak-over-threshold (POT) method, and the generalized extreme distribution (GEV) and generalized Pareto distribution (GPD) were used to fit the two precipitation series and to investigate their statistic characteristics. The best distribution was determined by the Kolmogorov-Smirnov test and then the best distribution was used to estimate the precipitation extremes in different return periods.  The results showed that： (1) the precipitation extremes in the north bank of the Yangtze River were greater than those in the south bank, the Kaizhou station is the peak of extreme precipitation in the TGRIB. (2) the optimal distribution for the AM series were GEV distribution, and the best distribution for the POT series were GPD distribution. The distributions of precipitation extremes in different return periods derived from two combinations of GEV-AM and GPD-POT were similar, but the estimated precipitation amounts by the GEV-AM combination were larger than that of the GPD-POT combination in the different return periods. It provides a certain reference for the flood control operation of the Three Gorges Reservoir and the prevention and control of geological disasters in the TGRIB.
