Abstract

Generally, roofs are the best candidates for rainwater harvesting. In this context, the correct evaluation of the quantity and quality of runoff from roofs is essential to effectively design rainwater harvesting systems. This study aims to evaluate the performance of a kinematic wave based numerical model in simulating runoff on sloping roofs, by comparing the numerical results with the ones obtained from laboratory rainfall simulations on a real-scale Lusa ceramic tile roof. For all studied slopes, simulated discharge hydrographs had a good adjust to observed ones. Coefficient of determination and Nash–Sutcliffe efficiency values were close to 1.0. Particularly, peak discharges, times to peak, peak durations and runoff volumes were very well simulated.
