Before configuring an Irrigator Demand Model on a Water User node, you must specify crop factors for the entire scenario using Crop factors defined in this way are accessible for each water user node. More details regarding this can be found under IQQM CropMod2 Demand Model(insert link here)
District Configuration
This describes a number of parameters that can be set at an irrigation district level. The maximum irrigated area is a nominal area that can be set because the total area planted within a water year is not limited other than through the planted area. A warning is then recorded runtime if the planted area exceeds the maximum irrigated area of the district. Soil moisture capacity is specified at the district level and this is assumed constant for all crops in the district. If user has specified irrigation season, orders and requests are only generated within the season. Both irrigation and opportunist requirements can be limited to within an irrigation season.

Supply Escape
The district requirement is adjusted to allow for any district delivery supply escapes and losses associated with delivering water to the district. This is optional in the demand model configuration and can be added by right clicking the Irrigator (menu item) and selecting Supply Escape. It is expressed as a percentage
Return Efficiency
Returned water is surplus drainage water from irrigation or from rainfall runoff. This water can be redirected into the on farm storage or otherwise can be returned to the river via a confluence node. This is optional in the demand model configuration and can be added by right clicking the Irrigator (menu item) and selecting Return Efficiency. It is expressed as a percentage
