由于气候变化，地势低洼的沿海城市洪水泛滥。在这些城市，雨水管道出口可能在涨潮时被沿海水域淹没，或被风暴潮淹没，导致无法排水。这项研究的目的是评估雨水致动器的模型预测控制(MPC)在沿海城市环境中减少因海平面上升而恶化的洪水的有效性。雨水系统和控制场景使用美国环境保护局雨水管理模型(SWMM5)和Python库swmm_mpc进行模拟。研究地区是美国弗吉尼亚州的诺福克，这是一个特别容易受到沿海洪水影响的城市。模拟的2年12小时风暴和海平面上升高达3.5英尺的设计情景被应用于模型的三种控制情景：1)被动系统，2)带有防潮闸的被动系统，以及3)通过MPC控制的潮汐闸门和三个执行器(一个泵、一个阀门和一个充气坝)。被动系统中的洪水达到了临界点，在海平面上升1.6英尺后急剧增加。潮汐闸门的增加极大地缓解了洪水的增加。MPC进一步减少了总的洪水，平均有效减少了32%。使用MPC的洪水增加速度明显小于不使用MPC的速度。对于海平面上升2.0英尺及以上，MPC还将最大节点洪水流量平均减少了52%。除了安装潮汐闸门外，我们的结果表明，使用由MPC控制的致动器可以显著减少总体洪水流量，并降低沿海城市个别节点的洪水严重程度。
Low-lying, low-relief coastal cities have seen increased flooding due to climate change. In these cities, stormwater pipe outlets can be inundated by coastal waters at high tide or from storm surge, making drainage impossible. The objective of this research is to assess the utility of model predictive control (MPC) of stormwater actuators to reduce flooding in a coastal urban setting made worse by sea level rise. The stormwater system and the control scenarios are simulated using the United States Environmental Protection Agency Storm Water Management Model (SWMM5) coupled with a Python library, swmm_mpc. The study area is Norfolk, Virginia, USA, a city which is particularly vulnerable to coastal flooding. A simulated 2-year 12-h design storm and sea level rise scenarios up to 3.5 ft are applied to the model for three control scenarios: 1) a passive system, 2) a passive system with a tide gate (backflow preventer), and 3) a tide gate and three actuators (a pump, a valve, and an inflatable dam) controlled through MPC. Flooding in the passive system reached a tipping point and increased dramatically after a sea level rise of 1.6 ft. The addition of a tide gate greatly mitigated this increase in flooding. MPC further reduced overall flooding with an average effective percent reduction of 32%. The rate of the increase in flooding was significantly smaller with MPC than without. MPC also reduced maximum node flood volume by an average of 52% for sea level increases of 2.0 ft and above. In addition to the installation of a tide gate, our results suggest that the use of actuators controlled by MPC could significantly reduce overall flood volumes and reduce flood severity at individual nodes in coastal cities.
