Tutorial: Irrigation Performance Indicators and Water Productivity

5. Compute Indicators Using Indicators Calculator Tab

5.2. Beneficial Fraction

The next indicator that we'll calculate is the Beneficial Fraction.

1. In the Indicator Selection dropdown, select Beneficial Fraction.

Beneficial Fraction measures the efficiency of on-farm water and agronomic practices, calculated as the ratio of Transpiration (T) to overall field water consumption (ETa).
    2. In the Formula Parameters, select the seasonal AETI raster (WH_L3_AETI_S_2022_10_01) and seasonal Transpiration (T) raster (WH_L3_T_S_2022_10_01).

    3. In the Indicator Computation section, name the output file as WH_BF_2022_10_01.

    4. Click on Calculate Indicator.

    5. The output is a raster stored in the Waplugin_workshop folder, and it will automatically load into QGIS. The mean and standard deviation values will be displayed in the plugin.
