摘要

本文介绍了Vipava河上5个测量站的低流量分析结果，该河具有Dinaric洪积地貌（流域面积590 km2）。低流量统计数据显示，Vipava测量站的流量值最低。基准流量指数（BFI）值在考虑的站点之间具有可比性，约为0.40。相对较低的BFI值表明土壤渗透性较低。所有测量站的年平均最小7天流量（MAM7）和第95百分位超越流量（Q95）之间的高度相似性表明气候温和。春季和秋季流量值最高，夏季流量值最低。在丰水年，流量波动相对较大，而在枯水年，流量主要由基流组成。流量-持续时间曲线分析也证实了这一点。季节性分析显示，夏季主要为低流量天气。

Comprehensive low-flow analysis of the Vipava river

The article presents the results of the analysis of low flows at 5 gauging stations on the Vipava River, which has a Dinaric pluvial-nival regime (catchment area of 590 km2). The low-flow statistics show that the gauging station Vipava stands out with the lowest values. Baseflow index (BFI) values are comparable among the considered stations and are around 0.40. Relatively low BFI values indicate low soil permeability. A high similarity between the mean annual minimum 7-day flow (MAM7) and the 95th percentile exceedance discharge (Q95) at all gauging stations indicates a temperate climate. The highest flows values occur in spring and autumn, and the lowest in summer. In wet years there are relatively large fluctuations in flow, while in dry years the flow consists mainly of baseflow. This is also confirmed with the flow duration curves analysis. The seasonality analysis shows a predominant summer regime with low flows.

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.
