A
comprehensive implementation framework has been suggested for the
determination of the past/present and future water demand of various
usages. These usages include municipal, industrial, agricultural,
livestock and fish farming demand. The analysis was based on
following out certain guidelines for estimating demand based on the
availability of data and its accuracy. Based on water consumption
forecasting, a water consumption estimate is obtained for each
component.
The
Water Demand Forecasting Models have been built in two forms. The
first is a simple form based on Spread (Excel) Sheet with proper
links. The second is an Oracle-based Model using the same components
of water demand forecasting.
The
water demand for different usages and governorates were carried out
using both the Spread-sheet and the Oracle-based Water Forecasting
Models. The results indicate continuous increase of water demand
values to all usages and corresponding continuous drop of water
demand per capita.
Effects
analyses have been carried out to identify various effects on water
demand forecasts caused by the underlying determinants of
consumptions. These effects are represented in the form of
ranges of coefficients at the specific year of influence. The
coefficients are either positive indicating the relative increase in
demand or negative showing a relative reduction in demand. The
values of these coefficients are gathered from the literature or
through expert experience and then adjusted to the Egyptian
circumstances.
