Abstract

In recent decades, an increase in the number of extreme flood events as well as extreme drought events has been observed in Slovenia. This rise the need for a comprehensive analysis of trends in discharge data series. In the study, statistical trends in seasonal and annual mean, maximum, extreme and low discharge values were investigated using the Mann Kendall test. The results show a temporal and spatial variability of trends in discharge. In general, a decreasing trend in water quantities in the rivers was observed. However, results at some gauging stations indicate statistically significant increasing trends, especially for maximum and extreme discharges. Additional analyses show that the discharge trends depend on the location of the gauging station.

气候变化对斯洛文尼亚河流流量波动的影响

近几十年来，斯洛文尼亚的极端洪水事件和极端干旱事件数量有所增加。这就增加了对流量数据系列趋势进行全面分析的必要性。在这项研究中，使用Mann-Kendall检验调查了季节和年平均、最大、极端和低流量值的统计趋势。结果显示了流量趋势的时间和空间变化。总体而言，观察到河流中的水量呈下降趋势。然而，一些测量站的结果表明，在统计上有显著的增长趋势，尤其是最大和极端流量。其他分析表明，流量趋势取决于测量站的位置。

期刊介绍： Acta geographica Slovenica publishes original research papers from all fields of geography and related disciplines, and provides a forum for discussing new aspects of theory, methods, issues, and research findings, especially in Central, Eastern and Southeastern Europe. The review accepts original research papers and review papers. Papers presenting new developments and innovative methods in geography are welcome. Submissions should address current research gaps and explore state-of-the-art issues. Research based on case studies should have the added value of transnational comparison and should be integrated into established or new theoretical and conceptual frameworks. The target readership is researchers, policymakers, students, and others who are studying or applying geography at various levels. Submissions are accepted in English or Slovenian.
