衰退分析是水文分析中众所周知的工具。然而，它的应用提出了许多系统性问题，并且在整个文献中已经寻求了许多解决方案。衰退曲线的量化涉及分析表达式的选择、特征衰退的推导以及衰退参数的优化。一个主要问题是各个细分市场的衰退行为存在很大的可变性。这些部分代表了流出过程的不同阶段，并且对衰退率的基于物理的短期或季节性影响增加了导出特征衰退的问题。本文讨论了衰退分析的这些要素，并回顾了表征基流衰退率的不同方法。
Recession analysis is a well-known tool in hydrological analysis. Its application, however, poses many methodical questions, and throughout the literature numerous solutions have been sought. The quantification of the recession curve involves the selection of an analytical expression, derivation of a characteristic recession and optimization of the recession parameters. A major problem is the high variability encountered in the recession behaviour of individual segments. The segments represent different stages in the outflow process, and a physically based short-term or seasonal influence on the recession rate adds to the problem of deriving a characteristic recession. This paper discusses these elements of recession analysis and reviews different ways of characterizing the baseflow recession rate.
