“…To maximize effectiveness, enhancing existing features such as water storage units and rain gardens in the basin, in addition to rivers and dams, can increase the basin's effective water storage capacity as a whole. Studies have shown that river improvement in Japan can handle excess floods more effectively than dam redevelopment, indicating the need to improve rivers to reduce the required storage capacity and the need to raise the dam embankment and increase the discharge pipe to increase the effective storage capacity [294].…”

Increasing frequency and intensification of flooding pose significant threats to critical structures, such as dams and levees. Failure of these structures can lead to substantial economic losses and significant adverse environmental and social consequences. Improving the resilience of these structures against climate-related impacts is important to avoid future risks of failure due to the potential intensification of flooding. National-level guidance on integrating resilience-based frameworks and addressing climate risks and uncertainties in existing design flood estimation methodologies for dams and levees are lacking. To address these gaps, this study first reviews projected climate change patterns for Canada and then discusses regional vulnerabilities of dams by considering significant historical floods and their consequences. Subsequently, a review of existing design flood estimation procedures, with a focus on frequency- and probable maximum flood-based approaches, is conducted to identify areas where climate change-related aspects can be integrated. By examining the challenges associated with various stages of design flood estimation procedures, the review discusses a framework for enhancing climate resiliency of dams and levees considering four pillars of resilience. Furthermore, Canadian design flood estimation practices are compared with international practices to identify areas that require attention. The study highlights the importance of a resilience-based framework in providing design and operation guidance to ensure that dams and levees are resilient to climate impacts. Policymakers and engineers can prioritize consideration of climate-resilience in the design and operation of these structures in order to safeguard communities and infrastructure from the growing risks of future floods associated with climate change.

“…Single reservoirs, sluices, or pumping stations can no longer effectively control flood risk. In contrast, the coordinated regulation of various types of water‐related infrastructure with the function of water flow regulation has become a reliable option in the current phase (Fekete, 2019; Kataoka, 2011; Nakamura & Shimatani, 2021; Shao et al, 2018; D. Zhu, Mei, et al, 2021). However, it is well known that there are often multiple stakeholders in urban flood risk management.…”

Extreme climate and urbanization lead to frequent urban floods, and urban water system dispatching is an important means of urban flood control. A coupled model is proposed to simulate urban floods in real-time and achieve comprehensive water system control for urban floods. First, the systematical description of coordinated drainage and regulation model of urban water systems in China is introduced, then the practice of Fuzhou city was taken as an example to introduce the prediction and forecast systems, as well as water system regulation for urban flood and waterlogging disaster in detail. Results show that the root-mean-square error of river flood prediction is less than 0.3 and that the calculation time of waterlogging simulation is less than 10 min; the optimization regulation reduces the peak river water level by 31 cm. This study will establish a novel urban water system management model to help urban managers better reduce the loss caused by urban floods.
