Modeling municipal water demand using box-jenkins technique

Abstract EN

The Box-Jenkins time series technique has been used to establish a monthly average water demand model for Riyadh city, the capital of Saudi Arabia.

The model is based on the actual monthly average water demand observed from January 1978 to December 1987.

In an ex-post forecast the model accurately predicts monthly variations in Municipal Water demand.

For medium term forecasts the developed model is expected to give more accurate future water demand forecasts than the trend extrapolation method adopted by the Riyadh Water Department.
