The Experimental Study on Infiltrating Characteristics of Different Mediums

Abstract

According to the column experiment of loess and loess-quartz mixed mediums of different proportion, we studied the changing rule of the wetting front ,infiltration capacity, and infiltration rate with time. The wetting fronts of the three mediums followed power relation against time, the correlation coefficients were all above 0.99.The fitting formula based on the relationship between wetting front and the time, and the correlation coefficients were above 0.97. With the proportion of quartz sand in mixed samples increased, the infiltration coefficient and infiltration rate increased.
