- Abstract:
- The traditional simulation modeling of low impact development (LID) is typically based on rough land classification and hydrological characteristics for planar layout, which leads to the inability to conduct refined layout modeling of sponge measures in the vertical three-dimensional space, and the synergistic combination effect on runoff control is frequently ignored or underestimated. Therefore, a vertical LID model construction method based on refined land use classification and enhanced hydrological characterization was proposed. By establishing the connected route of runoff and the calculation of flow flux in the LID simulation model, the interconnection and transfer of runoff from diverse sponge measures were accomplished, thereby facilitating further infiltration, storage and transportation. The combination of sponge measures based on vertical layout exhibited a superior control effect on the total runoff and peak value, being 12.83%-26.30% and 17.14%-21.62% lower than that under the planar layout, and could offer novel ideas and technical support for the subsequent construction of sponge cities.
