在潮湿的天气中，单独的废水下水道中的流速变化通常归因于径流水的不适当连接。但是这些输入不是这种行为的唯一原因，通过泄漏缺陷或裂缝的渗透可以向收集管道提供大量流量。这些流量的特性不是一件容易的事，因为它们涉及复杂的过程，不仅取决于降雨事件，而且还取决于水文条件和季节。使用16个月的每小时测量的降雨量和流速，我们开发了一个六参数的概念模型来模拟降雨诱导的渗透到一个小的下水道系统。灵敏度分析表明，该模型在各种校准条件下取得了良好的成绩，但显示高参数的相互作用，这可能是一个严重的缺点，一些特定的模型使用。模型应用到另一个污水管网产生了良好的协议之间的观察和模拟流量。该模型的适用性必须在其他网站上进一步检查。
Flowrate changes in separate wastewater sewerage during wet weather are often attributed to inappropriate connections of runoff water. But these inputs are not the only cause of such behaviour and infiltration through leaking defects or cracks can supply large flows into collection pipes. The characterization of these flows is not an easy task since they involve complex processes, depending not only on rainfall events but also on hydrological conditions and seasons. Using 16 months of hourly measurements of rainfall and flowrates, we developed a six parameter conceptual model to simulate rainfall induced infiltration into a small sewer system. Sensitivity analysis applied to the proposed model showed good achievements under various calibration conditions but displayed high parameter interactions which may be a serious drawback for some specific model uses. Model application to another sewer network yielded good agreement between observed and simulated flows. The suitability of this model must be further checked on other sites.
