Numerical modeling of the soil-water dynamics in water-wind erosion crisscross region on the loess plateau

  • The soil-water balance is very important in the ecosystem restoration in the typical water-wind erosion crisscross region on the Loess Plateau.An effective way to study the water balance is modeling.In this paper, a numerical model, soil-water-atmosphereplant model (SWAP), is used to simulate the water balances and evapotranspiration in different land use patterns based on field observations.The results of SWAP model simulating soil-water balance are consistent with the observed values in different land use patterns.The model can simulate soil-water dynamics of the loess slope land after some parameters are adjusted according to the measured values.The outputs of SWAP model can be used to analysis water balance daily, and the daily evapotranspirations of millet and alfalfa are 1.2-2.6 and 1.2-2.5, respectively.
