内容記述 |
Effects of macropore flow on solute transport in a variably saturated medium under repetitive rainfall events were investigated by rainfall-infiltration experiments. The effects of macropore flow were classified into three categories depending on rainfall amount relative to evaporation and storage change during a period of interest. Macropores were found to contribute to faster infiltration under heavy rainfalls, while they contribute to larger vertical dispersion in all rainfalls including light rains which do not initiate macropore flow. Rainfall intensity has an influence on the onset of the macropore flow. Macropore flow in high antecedent soil water content conditions causes greater vertical spreading of the solute due to small lateral infiltration from macropores into matrix. The effects of macropore flow on solute transport in the variably saturated medium were most apparent under intermediate strength rains in our experimental conditions. |
