Abstract The rapid development of the city leads to continuous updating ratio land use allocation, especially during flood season, which will exacerbate significant changes in spatial and temporal patterns urban flooding, increasing difficulty forecasting early warning. In this study, evolution flooding a high-density area was analyzed based on Mike Flood model, influence mechanisms different rainfall peak locations infiltration rate scenarios characteristics waterlogging were explored. results revealed that under same return period, larger coefficient, value inundation volume area. When coefficient is small, higher period is, lag time P = 50a, r 0.2, delay for depths H > 0.03 m 0.15 reached 32 min 45 min, respectively, At time, there are also differences depths. greater depth, longer volume, more effect prolongation. It worth noting increase lead advance area, overall obvious than volume. times advanced by 4 ~ 8 − 2 9 m, after rate; smaller time. capacities obtained study can help provide new perspective warning waterlogging.

Climate change and urbanization have led to an increase in the amount of water flowing into traditional drainage systems, which results frequent urban flooding. Low–Impact Development (LID) facilities, with their distributed feature, are one important means mitigate flooding been widely used. In this paper, based on integrated catchment management (ICM), we compare abatement runoff, flooding, ponding under two durations rainfall eight different return periods runoff as control objective (RACO) (FACO) for deployment LID facilities. The waterlogged area FACO is higher by a range 92.462 m2 24,124.39 compared RACO. Both percentage reduction overflow volume tend decrease gradually period. For per unit area, sometimes RACO greater than FACO, vice versa, while where exceeds between 0.29 10.95 (%/ha). cost has decreased 4.94% 46.20% This shows that FACO’s method can fully utilize capacity facilities inundation, reducing certain extent.

Rainstorm and the induced flood disaster often cause serious damage to transportation system, resulting in loss of life property. To improve resilience this study proposes a framework for assessing impacts rainstorm on road network based GPS data. The change ratio traffic flow congestion index are used evaluate disrupted detour sections caused by rainstorm. A method compared normal circumstances is proposed identify flood‐damaged sections. case Beijing verifies feasibility practicality framework, which can effectively assess from multiple spatial temporal dimensions, sections, supplement existing research. Research findings provide scientific basis emergency management departments accurately roads affected system.

ABSTRACT Based on the confluence principle, should represent aggregate of net rainfall confluences within each distinct basic watershed unit (BWU) a basin. The BWUs are categorized as V-type and Horseshoe-type based their shape characteristics two types time–area curves slope convergence have been derived separately. cascade river is modeled using lagged linear reservoir, resulting in development distributed CLARK model basin (BWU-DCLARK). key findings follows: (1) BWU-DCLARK effectively captures runoff process has successfully applied Yanduhe River Modeling results demonstrate high simulation accuracy. (2) time indicates that regulatory storage effects cannot be overlooked. (3) not only enables calculation flow at outlet but also facilitates computation any node along chain which great significance for hydrological forecasting un-gauged basins application effect will need further verification.

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