Under the influence of climate change, extreme rainfall events (EREs) have become increasingly frequent. The urban waterlogging caused by these has a particularly significant impact on cities with flat terrain and inadequate surface runoff dynamics. This study proposes Coordinated Regulation Storage Discharge Mode (CRSD) tailored for plain cities. It establishes an evaluation system CRSD based regional rainwater flood carrying capacity, drainage value, thereby assigning customized storage strategies to different areas. model optimizes relationship between across regions fundamental principles dynamic cross-regional water distribution rules according optimization objectives. Finally, is validated using MIKE models. results indicate that as return period increases, area affected expands, though proportion various severity levels remains stable. can effectively alleviate EREs, reduction percentages ranging from 12.21% 18.50%. Among schemes, Safe Consumption (SC) delivers best overall performance, reducing up 1.80 km2 under 500 yr. Average Pressure (AP) performs in high-value areas, 1.96 same period. advances management integrating coordination mechanisms blue–green–grey infrastructure, providing replicable strategy flatland cope increasing challenges EREs.

Stochastic channel network modeling is an informative tool to replicate river networks for the purpose of understanding variability geometry and distinguishing observed patterns in networks. In contrast, application stochastic models artificial or urban drainage not common despite their practical implications engineering purposes. Gibbs’ model a useful investigate characteristics also has advantage produce alternative with same due its nature as model. This study utilized estimate configuration Seoul, South Korea, increased number flow directions from four (N, E, S, W) eight NE, SE, SW, W, NW), which enables improved accuracy. Based on that, affects hydrological response directly, results this imply new design criterion concerns connection upstream downstream subcatchments different configurations mitigate flooding. Additionally, order evaluate model’s usefulness be employed hydrologic responses actual networks, width function-based IUH (WFIUH) was applied highly urbanized pipe-networked catchment Shinweol Watershed Korea.
