Effect of Clay and Sand Grade of Muddy-Water on Its Characteristics of Intermittent Infiltration

This paper studied the characteristics of muddy water intermittent infiltration based on the field experiment data． The reducing infiltration effects of the different clay and sand grade were studied further． The results showed that the 0.01 mm physical clay particle contents of clay and sand are the main affecting factors of muddy water infiltration, and using the physical clay content instead of the clay and sand grade as the influencing factor of muddywater infiltration is better.
