Urban stormwater infiltration basins are designed to hold runoff from impervious surfaces and allow the settling of sediments and associated pollutants. However concerns have been expressed about the environmental impacts that may be exerted by the trapped pollutants on groundwater, soils and ecosystems. In this context, sediment characterization represents a key issue for local authorities in terms of management strategies. During the last two decades, several studies were launched including either physical or chemical characterization of stormwater sediments but without real synthesis of data and methods used. Consequently, there is an important need for reviewing the current experimental techniques devoted to the physico-chemical characterization of sediment. The review is based on the outcomes of two experimental sites for which long term monitoring and data collection have been done: the Cheviré basin (near Nantes) and the Django Reinhardt basin (near Lyon). The authors summarize the studies dealing with bulk properties, pollutant contents, their potential mobility and speciation. This paper aims at promoting the significant progresses that were made through a multidisciplinary approach involving multi-scaled and combined experimental techniques.
城市雨水渗透盆地旨在容纳不透水表面的径流，并允许沉淀物和相关污染物沉淀。然而，人们对被截留的污染物可能对地下水、土壤和生态系统造成的环境影响表示担忧。在这种情况下，沉积物特征描述是地方当局在管理策略方面的一个关键问题。在过去的二十年中，开展了几项研究，包括对雨水沉积物进行物理或化学特征描述，但没有真正综合使用的数据和方法。因此，有必要对当前用于沉积物物理化学特征描述的实验技术进行审查。该综述基于两个长期监测和数据收集的实验点的结果：Cheviré 盆地（靠近南特）和 Django Reinhardt 盆地（靠近里昂）。作者总结了有关总体性质、污染物含量、潜在迁移性和形态的研究。本文旨在通过涉及多尺度和组合实验技术的多学科方法，促进取得重大进展。
