摘要: Solute transport in soils is commonly simulated with the advective-dispersive equation, or ADE. It has been reported that this model cannot take into account several important features of solute movement through soil. Recently, a new suggested results equation fractional spatial derivatives, FADE. We have assembled database on published experiments soil columns to test model. The FADE appears be useful generalization order differentiation reflects differences physical conditions
