“智能”水系统通过对以前静态的基础设施进行实时监测和控制，正在改变雨水管理领域。虽然积极控制的局部效益是公认的，但对流域系统规模控制的潜力知之甚少。这项研究展示了如何利用现实世界的智能雨水系统来塑造城市流域内的径流。具体来说，我们协调释放从两个互联网控制的雨水流域，以实现所需的控制目标下游，如保持流量在一个设定点，并产生交错波。在研究的第一部分中，我们描述了使用低成本，开源硬件堆栈和基于云的控制器调度应用程序的控制网络的构建。接下来，我们通过确定从上游滞留盆地释放的各种波的旅行时间，衰减时间和幅度来表征系统的控制能力。有了这个特性在手，我们使用该系统在一个关键的下游路口产生两个所需的响应。首先，我们生成一个设定点过程线，其中流量保持在一个近似恒定的速率。接下来，我们生成一系列重叠和交错的波使用定时释放从两个保留盆地。我们将讨论如何使用这些控制策略来稳定流量，从而减轻河床侵蚀和减少污染物负荷到下游水体。
“Smart” water systems are transforming the field of stormwater management by enabling real-time monitoring and control of previously static infrastructure. While the localized benefits of active control are well-established, the potential for system-scale control of watersheds is poorly understood. This study shows how a real-world smart stormwater system can be leveraged to shape streamflow within an urban watershed. Specifically, we coordinate releases from two internet-controlled stormwater basins to achieve desired control objectives downstream—such as maintaining the flow at a set-point, and generating interleaved waves. In the first part of the study, we describe the construction of the control network using a low-cost, open-source hardware stack and a cloud-based controller scheduling application. Next, we characterize the system’s control capabilities by determining the travel times, decay times, and magnitudes of various waves released from the upstream retention basins. With this characterization in hand, we use the system to generate two desired responses at a critical downstream junction. First, we generate a set-point hydrograph, in which flow is maintained at an approximately constant rate. Next, we generate a series of overlapping and interleaved waves using timed releases from both retention basins. We discuss how these control strategies can be used to stabilize flows, thereby mitigating streambed erosion and reducing contaminant loads into downstream waterbodies.
