英文摘要	The infiltration process is a critical link between surface water and groundwater. In this research, a specific device to observe infiltration processes in homogeneous and heterogeneous soils with triangular and inverted triangular profiles was designed, and the Green-Ampt model was employed for the process simulation. The results indicate that (1) the wetting front in coarse texture soils transports faster than in fine texture soils; (2) for the homogeneous case, the wetting front in triangular-shaped soils transports faster than the inverted triangular type, but the triangular-shaped soils show a lower infiltration rate; (3) in the initial step, the wetting front in triangular-shaped soils shows higher transport speed, but depicts lower speed with increase in the time; (4) both the wetting front and infiltration rate show a significant exponential relation with the time. From these findings, an empirical model was developed which agrees well with the observed data and provides a useful method for this field of soil research.
