Online Monitoring-based Runoff Control Method for Rain Garden System
For present conventional rain garden systems,the runoff control is realized mainly by building rainwater reten-tion facilities such as green roofs,which leads to poor runoff control due to lack of analysis approach to drainage pipe to-pology.In this regard,an online monitoring-based runoff control method for rain garden systems is proposed.The method uses sensing devices to realize real-time monitoring of runoff volume and adds water storage functions.Based on the moni-toring results,the differences in drainage pipe topology are quantified and analyzed,and the runoff volume control is re-alized by adjusting parameters such as simulated precipitation and storage volume.In the experiments,the proposed method is validated for its regulation performance.The results show that the proposed method has a high attenuation rate of surface runoff when it is used to control the runoff volume,and has a better runoff volume control capability.
