In this study, two parameterizations for different irrigation techniques have been
implemented in a regional climate model. These implementations allow for a comparative
study of water use and land–atmosphere interactions associated with traditional flood
irrigation—a widespread but highly water-inefficient practice—and water-conserving drip
irrigation. Both parameterizations yield realistic results for coupled climate simulations,
and do so without the need to reproduce an entire crop model within the climate model.
Simulations with drip irrigation exhibit 30% less irrigation season evapotranspiration
and 60% less water demand overall relative to simulations with flood irrigation.
