Abstract
To estimate daily sectoral urban water consumption considering the changes in characteristics of water consumption such as popularization of water saving appliances is important for reservoir operation during drought period or designing long-term water resources management planning. Univariate temporal disaggregation method previously suggested estimates daily sectoral water consumption from monthly or bimonthly metered water consumption. This method cannot take account of rainfall or weekly cycle. In this paper, multivariate temporal disaggregation method is applied to utilize not only monthly metered water consumption but also daily urban water consumption. Estimated daily sectoral water consumption by this method can consider daily fluctuation. This method was effectively applied to the estimation of daily sectoral water consumption in Matsuyama City in Japan.
