Research of the Simplification Macrospores Infiltration Model

Abstract:

A simplification model of infiltration in clay soil was developed. The model consisted of two flow domains: soil matrix and macrospores. The model was tested against the results of infiltration transients through a large clay soil column. In order to quantify model parameters, characterization of soil matrix was carried out, providing hydraulic conductivity curve. All of the other model parameters were obtained by calibration due to lack of relevant experimental data. The proposed model proved to be able to adequately simulate measured breakthrough curves as well as temporal evolution of water content profiles along the sample.
