洪水频率和强度的增加导致了一个新的重点，利用非结构性的方法来减轻洪水，并在整合非结构性和结构性的方法为同一目标。在流域内，湿地、滞洪池和水库在减轻洪水方面发挥着至关重要的作用。然而，在许多情况下，这些存储系统的有效性似乎是有限的，因为除了存储限制之外，它们通常不以协调的方式操作。我们认为，通过协调一致地使用所有流域蓄水系统，并对预测的风暴事件做出反应，可以实现流域尺度的洪水缓解。这项工作的目的是提出一个软件和硬件架构的存储系统，如水库，滞洪池和湿地减轻洪水的阵列的优化和协调运行。这种方法将使湿地在降雨前几小时或几天适应性地释放水，从而最大限度地提高储存能力并减轻洪水。作为该框架的一部分，我们已经开发了一个模块化的硬件/软件平台，用于连接自动虹吸管/闸门，水位传感器和传感器控制/通信，以实现湿地，滞洪池和水库中的一系列驱动水释放硬件的远程操作。远程操作使用3G/4G蜂窝连接执行。该决策支持系统结合了水文建模，洪水建模，鲁棒优化，生态和业务约束模块。遥控系统是一种相对廉价的防洪方法。一种低成本的方法来操纵湿地，滞洪池和其他存储系统的存储可以打开大门，以一个新的成本效益的方法，防洪和其他目标。
Increasing flood frequency and intensity is leading to a new emphasis on utilizing nonstructural approaches for flood mitigation and in integrating nonstructural and structural approaches for the same objective. Within a watershed, wetlands, detention ponds, and reservoirs play a vital role in mitigating floods. However, in many cases, the effectiveness of these storage systems appears to be limited because they are often not operated in a coordinated manner besides storage limitations. We claim that improved flood mitigation at the watershed scale could be achieved by using all watershed storage systems in a coordinated manner and in response to forecasted storm events. The aim of this work is to present a software and hardware architecture for the optimal and coordinated operation of an array of storage systems such as reservoirs, detention ponds, and wetlands for mitigating floods. This approach will enable adaptive release of water from wetlands hours or days ahead of rainfall events, thereby maximizing storage capacity and mitigating floods. As part of this framework we have developed a modular hardware/software platform for interfacing automated siphons/gates, water level sensors, and sensor control/communication to enable remote operation of an array of actuated water releasing hardware in wetlands, detention ponds, and reservoirs. The remote operation is performed using 3G/4G cellular connection. The DSS combines modules of hydrological modeling, inundation modeling, robust optimization, and ecological and operational constraints. The remotely-controlled system is a relatively inexpensive method for flood mitigation. A low-cost way to manipulate the storage in wetlands, detention ponds, and other storage systems could open the doors to a new cost-efficient method for flood control and other objectives.
