Depositional crusts form when turbid water infiltrates into soil. These crusts reduce the rate of water penetration. Hydraulic conductivity of two California soils was measured as a function of volume of suspension infiltrated and electrolytic concentration in the range less than equivalent to 0. 005 M. Whereas the hydraulic conductivity of the bulk soils was not affected by electrolytic concentration; the hydraulic conductivity of the soil columns with depositional crust increased by two orders of magnitude as the electrical conductivity (EC) of the suspension increased from 0. 1 to 0. 55 dS m** minus **1. Saturated hydraulic conductivity of depositional crust made of flocculated particles was much higher than saturated hydraulic conductivity (HC) of crust made of dispersed clay and silt particles.
