Gross Irrigation Use

Gross irrigation use is summarised by irrigation center as monthly volume in m³ . It is the farmgate irrigation use divided by the distribution efficiency.

Gross irrigation use is only calculated for reference years. The user has to estimate system (= distribution) efficiency and the year-type (dry, medium or wet) for that year and the selected irrigation centers.

Note: The external storage of these assumptions in text files (as indicated in the COMMENTS field) is to be moved into a LOG table.

All calculated records are automatically given the MEASUREMENT_METHOD = "E". Thus, there is a possibility to additionally store monitored figures MEASUREMENT_METHOD = "M", which may be available for the Jordan Valley.
