| Abstract: | Macropores are very easy to be investigated in field soil. A comparing test was conducted to study the effects of macropore on water movement and solutes transport in two soil samples taken from a same field. One soil sample represents undisturbed soil and the other represents refilled soil. The classic approach of the Richards equation and advection dispersion equation is used to describe the transport of water and solutes in undisturbed soil and in refilled soil. Model parameters embody the different structure characteristics of the two soil samples. |
