“…The SWMM (Storm Water Management Model) is a distributed hydrological and hydrodynamic modeling tool developed by the U.S. Environmental Protection Agency (EPA). It is primarily utilized for simulating urban water quantity and quality over single events or extended periods (Tan et al,2024). SWMM is extensively applied in the numerical simulation of urban flood, design and planning of urban pipe networks, analysis of Low Impact Development (LID) measures on rainwater management among other studies (Jeung et al,2023;Xu et al,2022;.…”

Low Impact Development (LID) theory represents a new paradigm for sustainable urban development, focusing on enhancing stormwater management, mitigating urban flooding, and reinforcing urban planning. In this study, we select Tongzhou District in Beijing as study area, establish an improved coupled hydrologic-hydrodynamic model based on SWMM and TELEMAC-2D model that integrates the dynamics of surface, pipeline networks, and river channels through one-way coupling method. The drainage capacity of pipe network and surface inundation under rainfall during different recurrence periods were simulated and analyzed. The results show that the concept of LID, also known as sponge city transformation in China, offers significant flood mitigation benefits for the megacities. As rainfall return periods increase, the number of overflow nodes and overloaded pipelines is observed by increase rapidly and become stable in study area. Specifically, under 100 year return period rainfall scenario, the original model projected a maximum inundation depth of 0.407m and an overflow node proportion of 20.8%. Through the comparison simulation result of coupling model suggest prioritizing the reconstruction of pipelines under the first-grade roads and overpasses, followed by LID rebuilding around the river to effectively increase urban infiltration rate and mitigate river overflow risks.

“…To effectively address this challenge, some scholars have conducted in-depth research on measures to mitigate waterlogging disasters. Firstly, sponge cities represent an important engineering measure of reducing urban waterlogging disasters [8][9][10][11]. Facilities associated with sponge city construction perform functions such as infiltration, retention, storage, and purification.…”

In recent years, urban waterlogging disasters have become increasingly prominent. Physically based urban waterlogging simulation models require considerable computational time. Therefore, rapid and accurate simulation and prediction of urban pluvial floods are important for disaster prevention and mitigation. For this purpose, we explored an urban waterlogging prediction method based on a long short-term memory neural network model that integrates an attention mechanism and a 1D convolutional neural network (1DCNN–LSTM–Attention), using the diversion of the Jinshui River in Zhengzhou, China, as a case study. In this method, the 1DCNN is responsible for extracting features from monitoring data, the LSTM is capable of learning from time-series data more effectively, and the Attention mechanism highlights the impact of features on input effectiveness. The results indicated the following: (1) The urban waterlogging rapid prediction model exhibited good accuracy. The Pearson correlation coefficient exceeded 0.95. It was 50–100 times faster than the InfoWorks ICM model. (2) Diversion pipelines can meet the design flood standard of a 200-year return period, aligning with the expected engineering objectives. (3) River channel diversion significantly reduced the extent of inundation. Under the 30-year return period rainfall scenario, the maximum inundation area decreased by 1.46 km2, approximately equivalent to 205 international standard soccer fields.
