Droughts have impacted human society throughout its history. However, the occurrence of severe drought events in the last century and the concerns on the potential effects of climate change have prompted remarkable advances in drought conceptualization and modeling in recent years. This review intends to present the state-of-the-art on drought characterization and propagation, as well as providing insights on how climate dynamics and anthropogenic activities might affect this phenomenon. For this purpose, we first address the distinct concepts of droughts and their relationships. Next, we present two frequently utilized methods based on the run theory for drought characterization and explain the development and recovery stages of droughts. Then, we discuss potential drivers for drought occurrence and propagation, with focus on meteorological factors, catchments' physical characteristics and human activities. Later, we describe how droughts can affect several parameters of water quality. This review also addressed flash droughts, encompassing their definitions, commonly used indices, and potential drivers. Finally, we briefly address the roles of climate change and long-term persistence on future drought scenarios. This review may be useful for researchers and stakeholders for attaining a broader understanding on drought dynamics and impacts.
干旱在人类社会历史进程中一直产生着影响。然而，上个世纪严重干旱事件的发生以及对气候变化潜在影响的担忧，促使近年来干旱概念化和建模取得了显著进展。本综述旨在介绍干旱特征描述和传播方面的最新进展，并深入探讨气候动态和人类活动如何影响这一现象。为此，我们首先阐述干旱的不同概念及其相互关系。接下来，我们介绍两种基于游程理论的常用干旱特征描述方法，并解释干旱的发展和恢复阶段。然后，我们讨论干旱发生和传播的潜在驱动因素，重点关注气象因素、流域物理特征和人类活动。随后，我们描述干旱如何影响水质的几个参数。本综述还探讨了骤发干旱，包括其定义、常用指标和潜在驱动因素。最后，我们简要阐述气候变化和长期持续性在未来干旱情景中的作用。本综述对于研究人员和利益相关者更全面地理解干旱动态和影响可能会有所帮助。
