- Abstract:
- The detention basin has been demonstrated as a promising infrastructure solution in sponge city construction for urban flood control. However, research on their actual operating conditions and performance remains limited. The design conditions of a detention basin are further specified. Based on finite difference method, a simplified storage-outflow numerical calculation method (SO routing function) is proposed, which can be used to verify basin size and evaluate its effectiveness in peak flow control. By integrating the SO routing function with SWMM simulation, and utilizing measured data from eight rainfall events during Beijing’s 2025 flood season, the actual operational conditions and runoff control performance of the detention basin were analyzed. The result demonstrated that the design condition were successfully reproduced and the design objectives were achieved. Recommendations for hydraulic design optimization can be proposed to provide a reference for refining the detention basin design method.
