(Phys.org) —Connecting several data pipes in a popular land model, a research team led by Pacific Northwest National Laboratory simulated how irrigation from both surface water and groundwater affects the Earth's water and energy budget. The surface water irrigation results varied depending on the observational sources used. Seasonal and year-to-year variations were large, and tended to be more pronounced in dry versus wet years. Even when the model was calibrated with agricultural observations, the difference between simulations showed a wide variability.
