Abstract:
In order to accurately estimate the runoff coefficient for the quantity assessment of the roof rainwater harvesting system(RRHS), great differences in the value of event runoff coefficient(ψERC)were observed by field monitoring under different roof types(roof slope and material)and diverse rainfall distributions(rainfall depth and intensity)in three years(2010 to 2012)in Handan, Hebei, China. The results indicate that the distribution of ψERC is more highly correlated with the event rainfall depth than other factors. The relationship between ψERC and the rainfall depth can be well represented by the piecewise linear function. Further, based on the daily rainfall data over the period from 1960 to 2008, the value of the annual runoff coefficient(ψARC)is calculated. Although the total rainfall depth in each year is different, ψARC in Handan can be considered as a constant(0.62)approximately. The results can be used for the quantity assessment and performance analysis of the RRHS.
