Study On The Numerical Simulation Of Soil Water Movement For CN Irrigation

Based on theory of soil water dynamics, At frist, in this paper the parameters of unsaturated soil water movement, such as soil water characteristic cure, hydraulic conductivity and soil water diffusivity coefficient are dertermind by laboratory observation date. The second, study on the numerical simulation of soil water movement for CN irrigation, the calculated results were verified by laboratory and field test. At last, according to the analyzing and calculating, the model can be used to the soil water movement under condition of CN irrigation.
