Standard normal homogeneity test as a tool to detect change points in climate-related river discharge variation: case study of the Kupa River BasinPandžić, Krešo ...The study addresses homogeneity testing of annual discharge time series for eight hydrological stations and five annual climate time series for one weather station in the Kupa River Basin, between ... Slovenia and Croatia, and global annual average surface temperature time series for the period 1961%2010. The standard normal homogeneity test (SNHT) was used to detect both abrupt and gradual linear trend homogeneity breaks. The results reveal natural change points at the beginning of the 1980s. Absolute homogeneity testing of average annual weather station-level air pressure, annual precipitation, differences between precipitation totals and potential evapotranspiration and surface runoff from the independent observation time series confirmed an abrupt shift, also at the beginning of the 1980s. The trend of local air temperature for 1985%2000, which partly coincides with global surface temperature trend for 1974%2005, strengthened the river discharge regime shift since the beginning of the 1980s. These results could improve climate variation monitoring and estimation of the impact of climate variation on the environment in the area. Generally, an indication of climate regime change points and an assessment of their duration could provide significant benefits for the society.Source: Hydrological sciences journal = Journal des sciences hydrologiques. - ISSN 0262-6667 (lLetn. 65, št. 2, 2020, str. 227-241)Type of material - article, component part ; adult, seriousPublish date - 2020Language - englishCOBISS.SI-ID - 9054817
