通常采用干滞洪池来减轻城市径流对受纳水体的影响。它们目前依靠静态控制，通过固定限制其最大流出率。本研究探讨了几种增强管理策略的性能位于魁北克市附近的一个小城市集水区的出口，加拿大的干滞留池。在研究的增强方案中，有一些以前开发的实时控制（RTC）策略，以及依赖于每日手动调节出口闸门的新操作规则。这两种控制都利用了来自加拿大全球集合预报系统的初步或缩小尺度的降雨预报。考虑了使用预报集合传播的不同方式，以采取行动。考虑到三种不同的容积容量（包括现有的体积）的池塘性能进行了研究。RTC方案非常有希望。考虑到降雨预报，以防止池塘溢出的价值被证明。仅涉及每天手动调整的策略似乎没有帮助。
Dry detention ponds are commonly implemented to mitigate the impacts of urban runoff on receiving water bodies. They currently rely on static control through a fixed limitation of their maximum outflow rate. This study investigated the performance of several enhanced management strategies for a dry detention pond located at the outlet of a small urban catchment near Québec City, Canada. Among the enhanced scenarios studied are some previously developed real-time control (RTC) strategies, and new operating rules relying on a daily manual adjustment of the outlet gate. Both types of control make use of rainfall forecasts originating from the initial or downscaled Canadian global ensemble prediction system. Different ways of using the forecasts' ensemble spread were considered to take action. The pond performances were investigated considering three different volumetric capacities (including the existing volume). The RTC scenarios are very promising. The value of taking rainfall forecasts into account to prevent pond overflowing is demonstrated. Strategies involving only manual adjustments on a daily basis do not seem helpful.
