Model Calculations

The Agriculture Water Demand Model calculates the water demand for each polygon by using crop, irrigation, soil and climate parameters. Each polygon has been assigned an ID number – See Methodology.

It should be noted that in coastal regions like the Regional District of Nanaimo, many low-lying areas have high water tables which will reduce the overall irrigation demand.

Agricultural water demand results from the Model will therefore be higher than what may actually be used as water tables have not been taken into the equation.
