- •
Rice Irrigation System Soil and Water Assessment Tool (RIS-SWAT) is developed.
- •
Impact of water management on water cycle was evaluated using RIS-SWAT model.
- •
Compared with the current situation, a 20% reduction in canal water supply would not obviously reduce the rice yield.
- •
Temporal and spatial distribution of irrigation water in different subbasins has little impact on the water cycle in small watershed scale.
- •
20–40% reduction in canal water supply accompanied with much more ponds water supply would not reduce the rice yield.
