The consumption of water (a.k.a. water demand) is the driving force behind the hydraulic dynamics occuring in many water resources systems. Two basic questions need to be answered when building a water resources model that includes municipal water demand: 1. How much water is being used and 2. How does the usage change as a function of time? Water demands are often quantified using a unit of demand per capita applied to a seasonal factor. In this model, indoor and outdoor water demands are calculated separately using per unit water demands and a seasonal factor that is applied using a lookup table. Population is the driving factor behind the forecasted changes in water demands moving forward. A History Generator element is used to project population growth potential.
