Irrigation water demand: Irrigated agriculture is the largest water user in many basins High potential for increasing water efficiency (opportunity costs): Irrigation technology and management Crop choices, cropping patterns Water (economic) efficiency Socio-economic objectives

Crop selection, crop names, type, common planting date, CWR (crop water requiremen), a symbolic description of the vegetation period.

Crop data base, includes the main (physiological and economic) variables for different irrigated crops.

Detailed time series of crop growth, shading, and water use data.

Irrigation scenario editor, defining irrigation area and crop distribution.

Scenario checker: identifies incomplete/missing or inconsistent scenario assumptions/data.

Depending on “severitity”, warnings or error messages are generated.

Standard irrigation model scenario interface, top level.

Irrigation model scenario, results summary.

Irrigation model results, individual parameter time series.
