| Abstract: | The present situation of soil water dynamic parameters research are summarized and analyzed in this paper. In recent researches, soil water dynamic parameters are determined not only with experimental measures, but also with mathematical models based on elemental data. As the experiment conditions and simulating models are improved constantly, more and more factors concerned with the parameters are considered. But there are still shortages or limitations, and therefore are difficult in simulating practical soil water movement for all methods. |
