| Περιγραφή: | Under the trends of global urbanization and climate change, urban stormwater management has become increasingly critical in addressing urban flooding and water scarcity issues. Bio-retention facilities play a key role in stormwater management systems by reducing runoff volume and peak flow. Surface elevation is directly related to the layout of facilities by influencing their sink areas, runoff paths, and retention capacity. This study treats the raster cells of the digital elevation model as optimization variables to establish the linkage between surface elevation modification and layout objectives, and employs the Non-dominated Sorting Genetic Algorithm II (NSGA-II) to solve for retention space and facility layout. At a demonstration site in Copenhagen, the method was tested under different constraint scenarios and proved capable of rapidly generating solution sets based on three objectives: maximizing retention volume, maximizing sink area, and minimizing total earthwork. The resulting surface elevation changes in the solution sets exhibited clear spatial differences and a gradient of retention benefits. Furthermore, this paper discussed optimization efficiency, solution set probability visualization, and layout strategies, providing feasible roadmaps and insights for identifying potential stormwater retention spaces and improving blue–green infrastructure planning. |
