Tutorial: Irrigation Performance Indicators and Water Productivity

5. Compute Indicators Using Indicators Calculator Tab

5.6. Biomass Water Productivity (WPb)

The next indicator is the Biomass Water Productivity.

1. In the Indicator Selection dropdown, select Biomass Water Productivity.

Formula: WPb = (TBP / AETI) * 100This measures the amount of biomass produced per unit of water consumed.

2. In the Formula Parameters, select the Total Biomass
Production raster (WH_TBP_2022_10_01) and the seasonal AETI raster.

3. Name the output file as WH_WPb_2022_10_01.

4. Click Calculate Indicator. The output raster will be saved and loaded into QGIS.
