Ion patterns. The studies of Ahmad et al.  and Azam et al.  proved that shifting in Goralatide TFA precipitation patterns can only be determined by means of trend evaluation of precipitation based on month-to-month time scales. Consequently, the evaluation of extreme climate indices based on annual, seasonal, and monthly time scales, are necessary to identify the detailed climate variability in a catchment. In this study, the current effects of climate alter within the UGRB have already been investigated by means of a detailed trend evaluation of 17 extreme climate indices in the UGRB. The 17 core indices primarily based on each precipitation and temperature information, were analyzed primarily based on annual, seasonal, and monthly time scales. Additionally, the two non-parametric trend tests, the Mann endall trend test, and Theil en slope estimator approach, had been made use of to detect and quantify the magnitude of trends in the time series. Additionally, the Mann hitney ettitt test, was also employed to detect abrupt modifications within the time series. Lastly, the AZD4625 Data Sheet correlation in between trend magnitudes of all extreme climate indices, were also investigated in this study. The results offered in this study is usually utilized to decide the vulnerability in the UGRB against the recent climate situations. 2. Components and Approaches 2.1. Study Area The Geum River basin, situated at the central part of the nation, as shown in Figure 1, could be the third largest watershed next to Nakdong, and Han River basins. It has a catchment location of 9912 km2, as well as the URGB is situated in the most upstream part of the watershed, which constitutes 9.4 of Geum River basin. The UGRB is mostly characterized with mountainous topography, with elevations ranging from 204 m to 1608 m above sea level (a.s.l.). Moreover, Yongdam dam, a concrete faced rock fill, multi-purpose dam is situated at the outlet from the UGRB, and was completed on year 2001. Its catchment location is roughly 930 km2, having a reservoir area of 36.two km2, a storage capacity of 815 million m3 of water, plus a flood control capacity of 137 million m3. Based around the 33 years (1988 to 2020) of daily climate information at Jangsu station, retrieved from the Korea Meteorological Agency (KMA), the catchment has an average annual precipitation of 1373.44 mm with an typical variety of 150 wet days, and an typical temperature of 11.3 C.Water 2021, 13, x FOR PEER REVIEW3 ofWater 2021, 13,of 22 Agency (KMA), the catchment has an average annual precipitation of 1373.44 mm3with an average variety of 150 wet days, and an average temperature of 11.3 .Figure 1.
