摘要旱情分析在取水结构设计、水资源管理和环境问题应对中具有重要意义。在这种情况下，主衰退曲线代表了水文分析的一个工具，提供了关于长期干旱流量的综合信息。在本文中，开发了一种技术，用于直接从日流量序列中推导出主衰退曲线，该曲线考虑到个别衰退段行为的高度可变性。所开发的统计框架使我们能够明确地表示不确定性，从而推导出对主衰退曲线的新解释。该方法成功地应用于意大利东部阿尔卑斯山脉南坡排水的三个重要盆地。引证Fiorotto， V. and Caroni， E., 2013。掌握衰退曲线分析的新方法。水文学报，58(5),966-975。
Abstract The analysis of drought discharge is of utmost relevance in the design of water intake structures, management of water resources, and in coping with environmental issues. In this context, the master recession curve represents a tool in hydrological analysis, giving integrated information on long period drought flow rates. In this paper, a technique is developed for deriving a master recession curve directly from daily discharge series that takes into account the high variability in the behaviour of individual recession segments. The statistical framework developed allows us to explicitly represent uncertainty, and hence a novel interpretation of the master recession curve is derived. The method is successfully applied to three important Italian basins draining the southern slopes of the eastern Alps. Citation Fiorotto, V. and Caroni, E., 2013.
