- Abstract:
- The methods for calculating effective volume of peak flow regulation and storage facilities in existing specifications were introduced. According to Technical Code for Urban Stormwater Detention and Retention Engineering (GB 51174-2017) and the regulation and storage object, a new method for calculating the effective volume of peak flow regulation and storage facilities was proposed based on water balance, pipeline flow characteristics and process analysis. To avoid backwater transmission to the upstream and obstruction to upstream drainage facilities, the storage volume specified in the new method was calculated according to the actual flow of upstream pipeline and the designed drainage capacity of downstream pipeline at the proposed location of storage facility during rainfall. The rationality of the new method was verified by comparing the pipeline flow process and the highest water level before and after storage, which provided a new choice for the calculation of the effective volume of peak flow regulation and storage facilities.
