The intensity and frequency of hydro-meteorological hazards have increased due to fast-growing urbanisation activities and climate change. Hybrid approaches that combine grey infrastructure and Nature-Based Solutions (NBSs) have been applied as an adaptive and resilient strategy to cope with climate change uncertainties and incorporate other co-benefits. This research aims to investigate the feasibility of Real Time Control (RTC) for NBS operation in order to reduce flooding and improve their effectiveness. The study area is the irrigation and drainage system of the Rangsit Area in Thailand. The results show that during the normal flood events, the RTC system effectively reduces water level at the Western Raphiphat Canal Station compared to the system without RTC or with additional storage. Moreover, the RTC system facilitates achieving the required minimum volume and increasing the volume in the retentions. These findings highlight the potential of using RTC to improve the irrigation and drainage system operation as well as NBS implementation to reduce flooding. The RTC system can also assists in equitable water distribution between Klongs and retention areas, while also increasing the water storage in the retention areas. This additional water storage can be utilized for agricultural purposes, providing further benefits. These results represent an essential starting point for the development of Smart Solutions and Digital Twins in utilizing Real-Time Control for flood reduction and water allocation in the Rangsit Area in Thailand.
由于快速城市化活动和气候变化，水灾害的强度和频率有所增加。结合灰色基础设施和基于自然的解决方案（NBS）的混合方法已被用作一种适应和有弹性的策略，以应对气候变化的不确定性并纳入其他共同效益。本研究旨在调查实时控制（RTC）在 NBS 运行中的可行性，以减少洪水并提高其效率。研究区域是泰国 Rangsit 地区的灌溉和排水系统。结果表明，在正常洪水事件期间，与没有 RTC 或具有额外存储的系统相比，RTC 系统可有效降低 Western Raphiphat 运河站的水位。此外，RTC 系统有助于实现所需的最小体积并增加保留区的体积。这些发现强调了使用 RTC 来改善灌溉和排水系统运行以及实施 NBS 以减少洪水的潜力。RTC 系统还可以协助在运河和保留区之间公平分配水，同时增加保留区的储水量。这种额外的储水可用于农业用途，提供更多的好处。这些结果代表了在泰国 Rangsit 地区利用实时控制减少洪水和分配水资源方面开发智能解决方案和数字孪生的重要起点。
