Evapotranspiration (ET) consumptive use analysis

WaterWise quantifies actual water consumption using satellite-derived evapotranspiration (ET), then applies conservative hydrologic accounting to estimate the portion attributable to irrigation after effective precipitation is considered.

This approach distinguishes water that returned to the local system (runoff, seepage, recharge) from water that left the local system (ET). The result is a clear, physically grounded basis for beneficial use screening, non-use risk assessment, change applications, and injury analysis.

Deliverables are designed for legal and regulatory review: transparent assumptions, reproducible methods, and uncertainty bounds (low / expected / high irrigation CU) that help clients make confident decisions.
