“…Based on the results of previous research and discussions, the general conclusion that can be drawn is that the PUPRPKP (Public Works, Public Housing, Settlement Areas and Land) Service only handles flood management and waterlogging before and after they occur, not when a flood occurs (Lianbing, Daming, and Zhiming 2020). Implementation of policies in dealing with floods and waterlogging also involves a drainage development program which refers to the Regulation of the Minister of Public Works Number 12 of 2014 concerning the Implementation of Urban Drainage Systems (Xiong, Lu, and Tan 2023).…”

This research was conducted to determine the implementation of water absorption policies for flood management in urban areas, especially in the city of Cirebon at the Cirebon City Public Works and Spatial Planning (DPUPR) department. The research approach used is normative juridical, conceptualizing law as written norms so that this research emphasizes studies in the form of legislative products, namely those that regulate water absorption such as regional regulation number 38 of 2019 concerning the implementation of groundwater conservation through infiltration wells and infiltration holes. biopore. Policy implementation in flood management by the Cirebon City PUPR Service has included handling floods and puddles as a priority in the Regional Government Work Plan (RKPD) for 2025. For handling urban drainage, the PUPR Service's work target is to reach up to 83% by 2024, and 86% for 2025, and 89% for 2026. One of the strategies taken includes the creation of retention ponds, absorption wells and eco-drainage. However, there are still several obstacles in implementing this policy, such as limited resources and lack of community participation. To overcome these obstacles, efforts need to be made such as increasing the budget, providing adequate human resources, and educating the public about the importance of water absorption. Overall, the implementation of the water absorption policy for flood management in Cirebon City has shown a positive direction. With continued efforts and collaboration from various parties, it is hoped that this policy can be more effective in minimizing the risk of flooding in urban areas.

“…To achieve this goal, scholars have proposed and studied various methods. Some scholars have used network remodeling to reduce urban waterlogging, including those employing drainage network remodeling, such as Liu [22] who used the Storm Water Management Model (SWMM5.1) with maximum overflow depth, maximum overflow volume, and additional pipeline costs as key indicators to propose a new method for drainage network modification to eliminate urban waterlogging; studies on new drainage systems, such as that by Xiong [23], who proposed a new drainage system optimization method to eliminate urban waterlogging in a case study in Shanghai; and studies using siphon tubes, like Ren [24], who has innovatively proposed a siphonic underground drainage method. Its efficacy was assessed through indoor sandbox experiments and by using the Hydrus-2D model, confirming its effectiveness in eliminating urban waterlogging.…”

With the acceleration of urbanization and the impact of climate change, the frequent occurrence of urban waterlogging not only leads to road closures and traffic congestion but also severely affects the timeliness of urban emergency rescue. To accurately assess and enhance the response capability of urban emergency rescue under storm-induced waterlogging scenarios, a hydrodynamic model of urban waterlogging was developed to simulate waterlogging conditions under various design rainfall scenarios. By identifying road waterlogging risks and blocked roads, as well as combining the Two-Step Floating Catchment Area (2SFCA) method, the accessibility of emergency rescue services for points of interest (POIs) with different vulnerabilities was evaluated. The Liwan District of Guangzhou City was selected as a case study for accessibility impact assessment and improvement simulation. The results indicate that with the increase in the return period of rainfall, both the area and depth of waterlogged regions increased and the number of roads affected by waterlogging rose, leading to an increase in the length of blocked roads from 11 km to 49 km, an increase of over 300%. Additionally, the number of POIs inaccessible to emergency rescue increased, while the number of accessible POIs decreased, resulting in a significant downward trend in overall accessibility. By deploying mobile pumping vehicles, the depth and area of waterlogging under different rainfall return periods were reduced by over 10%, the number of blocked roads decreased by more than 10%, and the number of accessible POIs increased by more than 12%. The findings highlight that storm-induced waterlogging not only hinders traffic flow but also reduces the response capability of emergency rescue services. Through the strategic deployment of mobile pumping vehicles, the accessibility of urban emergency rescue services under waterlogging conditions can be effectively improved, mitigating the impact of waterlogging on urban functions and public safety.
