Abstract: With the comprehensive advancement of sponge city construction in Beijing, rainwater storage ponds have gained increasing application in urban stormwater management, emerging as one of the most significant source control facilities in the city. However, these facilities are characterized by a large number, small individual storage capacity, scattered locations, as well as issues such as a lack of coordinated operation and insufficient automation capabilities. Based on the need for refined management and control of sponge facilities, a smart regulation technology for rainwater storage ponds has been developed. This technology, centered on numerical simulation and logical algorithms, integrates online sensing and Internet of Things (IoT) devices to design scheduling strategies tailored to actual operational scenarios. The results demonstrate that the application of this smart regulation technology can achieve a peak reduction rate of 4.5% to 100% in the drainage network and up to 11.81% in sub-catchment flow. The technological advancements effectively enhance the performance of rainwater storage ponds, providing a new approach for intelligent operation and management of source control facilities.
