  • Based on soil moisture budget method, a soil water balance model for waterlogged winter wheat field was developed, which can be coupled with crop growth model. In order to simulate the soil waterlogging status, the calculation of capillary rise from the water table and the functions of hydraulic conductivity characteristics were incorporated. The simulated values of daily evapotranspiration were verified by the dataset from the pot experiments. The model was validated for water table and soil water contents for 0~10 cm, 10~20 cm, 20~30 cm, 30~40 cm and 40~50 cm soil layers using the observed data in Jingzhou and Jintan sites. Statistical analysis shows a good agreement between the simulated and observed data.
