Climatic and spatial variations of potential rainwater savings for Melbourne (Australia)

A daily water balance model is used for the performance analysis and calculation of potential rainwater savings from household rainwater tanks under different scenario for a major Australian city, Melbourne. To investigate the climatic variabilities of rainwater tank outcomes nine representative yea...
