Short summary

We assess changes in blue and green water scarcity in an anthropogenic highly impacted watershed and their association with climate change and land use change, using the multi-water-flux validated Soil and Water Assessment Tool. Observed streamflow, evapotranspiration, and soil moisture are integrated into model calibration and validation. Results show that both climate change and land use change decrease blue water, while land use change increases green water.
