在世界许多地区，由于社会和经济发展对土地利用造成压力，山区盆地的洪水事件是当地居民面临的最大风险之一。传统的水文-水力方法在山区盆地通常不可行，因为它们根本没有测量，或者在最好的情况下测量得很差。在这种背景下，古水文学研究为上述方法提供了一个有价值的替代方案。然而，许多古水文学数据源和相关方法已经被提出并最初用于具有广泛漫滩的大型盆地。因此，当它们在山区使用时，必须适应不同的技术，因为要解决的问题不同，而且通常可用的数据较少。在本文中，我们回顾了经典数据源和不同的分析方法，并讨论了它们的优点和缺点，特别关注山区盆地。为此，提供了一些例子，通过纳入不确定性、描述误差来源或提出水力计算假设来改进古水文学方法，以使古洪水水文学在风险评估中更加客观和有用。
In many regions of the world flood events in mountain basins are one of the greatest risks to the local population, due to the pressure placed on land use by social and economic development. Conventional hydrologic–hydraulic methodological approaches are not usually feasible in mountainous basins because they are not gauged at all or, in the best-case scenario, are poorly gauged. In this context, palaeohydrological research offers a valuable alternative to the above approaches. However, many palaeohydrological data sources and associated methods have been proposed and initially used in large basins with extensive floodplains. As a result, when they are used in mountainous areas they must be adapted to include different techniques, since the problems to be addressed are different and less data is usually available. In this paper, we review classic data sources and different analytical methods and discuss their advantages and shortcomings with particular attention to mountain basins. For this purpose, examples are provided where improvements in the palaeohydrologic methods are proposed by incorporating uncertainties, describing sources of error or putting forward hypotheses for hydraulic calculation to make palaeoflood hydrology more objective and useful in risk assessment.
