Procedure to Derive Parameters for Stochastic Modelling of Outdoor Water use in Residential Estates

The outdoor water use of residential properties is a major contributor to the seasonal fluctuation of the overall water use of these properties. The outdoor water use components were mathematically defined and combined to develop an outdoor water use model. The parameters that formed part of the mathematical outdoor water use model were formulated from data available for residential estates, where conditions such as types of vegetation, irrigated area and size of pool could be prescribed a home owners association or local authority. The data used to populate the model parameters was derived from aerial photography and contingent valuation methods.
