Figure 18: The basic information on basin insights
• Basin Map: An interactive map allows users to zoom in/out, reset to full basin extent,
and use additional features via a triangle icon.
• Land Usage: A double pie chart shows land use distribution:
o Utilized land: Natural landscapes used without resource modification.
o Managed water: Highly managed agricultural areas (e.g., irrigation).
o Modified land: Modified landscapes for rainfed crops.
o Protected land: Areas classified as protected (e.g., national parks).
o The inner pie chart further details land use within these categories.
• Year Selection: Allows users to toggle between years, comparing water balance and
yield changes over time.
2. Water Balance:
The water balance figure shows modeled estimates of key water balance terms. Each figure
is specific to the year selected on the year selection tab. It includes annual precipitation
received by the basin, total evapotranspiration (ET), and its two sources: Blue ET from blue
water sources (e.g., surface water bodies and groundwater) and Rainfall ET, or Green ET, from
soil moisture replenished by rainfall. The figure also provides information on basin outflow
and changes in basin storage due to groundwater abstraction or recharge.
