Runoff Control Performance of Smart Tanks
摘要
Abstract
[Objective]This study aims to explore the variation of runoff control performance of smart tanks,quantitatively to analyze the influence of key factors on their performance,thereby providing scientific referencesfor the design and runoff control performance evaluation of smart tanks.[Methods]This study developed a smart operating rule which was used for a tank water balance model based on daily rainfall and daily water demand data.The runoff control performance of the smart tank was quantitatively evaluated through three indicators,i.e.,stormwater capture efficiency,overflow rate,and overflow frequency.The influence of three main factors,i.e.,tank size,tank discharge upper limit,and rainfall intensity,on the three indicators was quantitatively analyzed to reveal the change rule of runoff control performance of smart tanks.[Results]The stormwater capture efficiencies of the smart tank and the conventional tank are equal and both rise with the increase in tank size.When the tank size ranges from 0 to 100 m3,the stormwater capture efficiency ranges from 0 to 87%.The overflow rate of the smart tank is 0 to 19%lower than that of the conventional tank of the same size.The overflow rate decreases with the growth of the discharge upper limit.The overflow frequency of the smart tank is 0 to 13%lower than that of the conventional tank of the same size.The overflow frequency rises with the increase in rainfall intensity.[Conclusion]The runoff control performance of smart tanks is better than that of conventional tanks.The impact of heavy rainfall intensity on the runoff control performance of smart tanks can be reduced by increasing tank size and discharge upper limit.关键词
