Potential and versatility of WEAP model (Water Evaluation and Planning System) for hydrological assessments of AWD (Alternate Wetting and Drying) in irrigated rice

摘要

The production of irrigated rice is increasingly challenged by freshwater scarcity. Water saving technologies such as Alternate Wetting and Drying (AWD) allow sustaining production levels under reduced water availability. Before implementing such innovations on a large scale, their hydrological impact on the system needs to be assessed.
