Abstract:
This paper proposed a 4D visualization method of urban waterlogging based on geographic information system (GIS) spatial analysis, so as to solve the problem that urban waterlogging cannot be displayed in multiple dimensions in SWMM model. The drainage network in the study area of a city in Fujian Province was generalized to construct the SWMM hydraulic model, and the measured rainfall was simulated and analyzed. The simulated waterlogging was visualized in 4D based on GIS spatial analysis, and the submerged area under different rainfall durations was basically consistent with the actual investigation results, indicating that the proposed method for 4D visualization of urban waterlogging was of good practicability. This method combined GIS spatial analysis tools with spatial mapping, and realized the visual multi-dimensional representation of urban waterlogging areas under rainstorm scenarios.
