Simulation of rainfall infiltration in stony soil

  • Based on the laboratory rainfall expermients,the process of rainfall infiltration in stony soil is numerically smiulated using the multiple interacting continua(MINC) method.The objective of this study is to further improve our understanding on water movement in stony soil.The results show that the maximum water saturation of soil can be increased if gravels present,while the total amount of infiltrated water and the infiltration depth in soil would be reduced accordingly.There is a steep wet front in the stony soil column,the max mium water saturation of soil decreases sharply along the front surface.The process of rain fall infiltration is well smiu lated by the MINC model.Both smiulated wet front and soil water content close to the observation.The reduction of rainfall in filtration depth in stony soil can be attributed to the change in the maxmium water saturation of soil along the soil profile during a rain fall.
