Experimental Study on the Soil Matrix and Macropore Saturated Hydraulic Conductivity

Undisturbed soil saturated hydraulic conductivity will influence the simulated precision of hydrological model directly,and then it will influence the precision of the models of water flow and solute transported in soil.Therefore,the soil of Qixia town in Nanjing was taken for example,through CT scan combined with empirical formula method and experimental measurement,macropore saturated hydraulic conductivity of undisturbed soil columns was acquired.And the detail comparative analysis of them were given.All of their analysis showed that relative deviation of the macropore's saturated hydraulic conductivity obtained from the two methods was less than 10%.
