Stormwater infiltration is a drainage mode, which is more and more used in urban areas in France. Given the characteristics of urban surfaces, and especially the loads of various pollutants contained in stormwater, it is important to assess the impact of stormwater infiltration systems on soil and groundwater by carrying out field experiments. The main difficulty is due to the complexity of the system observed and the need of multidisciplinary approaches. Another difficulty is that measurements are carried out in situ, in an uncontrolled environment submitted to quantitatively and qualitatively highly variable interferences. Very long term monitoring is needed to get representative results. In order to contribute to solve these problems, the OTHU project has recently been launched in Lyon (France). One of its key action concerns a long-term (10 years) experiment on an infiltration basin specifically rehabilitated for measurements and operational drainage issues. This paper presents the experimental site, the objectives of the project and the way the monitoring process has been built according to the various disciplines involved (biology, ecology, hydrology, chemistry and soil sciences) and to the will of assessing all the uncertainties in the measurement process.
雨水入渗是一种排水模式，在法国城市地区的应用越来越广泛。鉴于城市地表的特性，尤其是雨水中所含各种污染物的负荷，通过开展实地试验来评估雨水入渗系统对土壤和地下水的影响非常重要。主要困难在于所观测系统的复杂性以及需要多学科方法。另一个困难是测量在现场进行，处于一个受到数量和质量上高度可变干扰的非受控环境中。需要进行非常长期的监测才能获得具有代表性的结果。为了有助于解决这些问题，法国里昂最近启动了OTHU项目。其关键行动之一涉及在一个专门为测量和运营排水问题进行修复的入渗池上开展一项为期10年的长期试验。本文介绍了试验场地、项目目标以及根据所涉及的各学科（生物学、生态学、水文学、化学和土壤科学）以及评估测量过程中所有不确定性的意愿构建监测过程的方式。
