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.
