Abstract:

Infiltration process was one of the most important soil physical properties in the design, evaluation and simulation of the surface irrigation methods. In this paper, the infiltration model was summarized, all kinds of estimation methods of infiltration parameter were introduced, and the disadvantage and the merit of these methods were also pointed out in this paper. All of this offered academic foundation in the estimation method for the future. In addition, this paper also introduced the progress of the estimation method, pointed out the directions.
