Simulation Study on Irrigation Water Consumption of Multi-Source Irrigation Area based on Water Monitoring
2020
The simulation accuracy of irrigation water consumption in multi-source irrigation area is not high. SWAT model water cycle simulation structure and calculation of water balance elements are not suitable for irrigation district water cycle simulation. This paper puts forward a method of building water measurement and monitoring facilities in the main water circulation nodes of irrigation area, combining with the improved SWAT model to establish water circulation model to simulate agricultural water consumption in irrigation area. This method effectively realizes the combination of direct measurement and model calculation of agricultural irrigation water consumption in multi-source irrigation area.
