E (IPCC) [3] recommended that the characterization of each historical and future SB 271046 Protocol climate trends, to ascertain the effects of worldwide warming on the frequency and intensity of extreme weather events, is crucial for assessing and building tactics to decrease and regulate the impacts of climate modify. In particular, trends in the temperature and precipitation are deemed as two of the most important variables in understanding the climate, as the variation in these two climate variables can simply cause variation in the hydrological cycle [4]. While, the evaluation of future climate trends is essential for future climate threat assessments, the evaluation of historical observed data plays a very important role in recognizing the existing effects of global warming as compared in the past. In terms of water resources, the trends of climate variables needs to be accurately analyzed for a lot more effective management of dam operations, like preserving effective and safePublisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations.Copyright: 2021 by the authors.

In year 2020, South Korea was heavily devastated with excessive precipitation for the duration of monsoon season (that is also locally referred to as `Jangma’ season, and henceforth referred to as Jangma season), which brought 54 days of consecutive precipitation inside the central a part of the nation, marking the highest record to date [7]. As a result of these intense events, the upper Geum River basin (UGRB) was brought with 378 mm of 2-day precipitation (highest record in 55 years), a rise of 40 of its prior of 270 mm (189 August 2004) [8]. Because of the unpredicted extended Jangma season, Yongdam dam almost reached its full reservoir capacity at 98.9 (highest recorded data considering the fact that year 2001), and had to release approximately 14.7 (approximately 119.94 M cubic meters; the highest record of released dam water) of its reservoir capacity on 8 August 2020; the sudden release of dam waters brought on downstream flooding within the region. Hence, to prevent future water-related disasters in a catchment, a detailed investigation of trends in climate variables really should be performed. A set of regular measurements in the intense climate indices based everyday precipitation, and day-to-day (minimum and maximum) temperatures had been provided by the Professional Team on Climate Change Detection and Indices (ETCCDI) [9,10]. For the previous two decades, research on trend evaluation of ETCCDI indices [113], has been extensively performed in distinctive regions about the globe, by way of the use of Mann endall (MK) trend test [246] and Theil en (TS) slope estimator [27,28], each tests are rank-based non-parametric tests, which are insensitive to outliers and missing information. These recent research had been analyzed primarily based on a variety of temporal scales, ranging from annual [113], seasonal [13,179], and month-to-month [19] time scales. Though, majority with the studies focused on annual scales, and lesser on monthly scales, the former is insufficient in delivering detailed facts within a watershed, such as detecting shifting of precipitat.
