- Abstract:
- Hydrological model tests were employed to investigate the performance of bioretention ponds by central composite response surface method, and a response prediction model of rainfall control and peak change rate was established and then verified by statistical tests. Significance of each prediction model was relatively high, and the test values were well fitted to the predicted values. At the same time, parameter values for Ningbo City to achieve sponge city water objective were suggested. Based on the optimization principles of effectiveness, economy and purposiveness, it was suggested that soil layer infiltration rate, subsurface concave depth, design retention time and service area of the bioretention facilities were 356-400 mm/h, 135-215 mm, 12-24 h and 12-20 times, respectively, and good performance of the bioretention facilities was achieved under this condition.
