✦ Synopsis

This paper uses a numerical simulation to develop an expression for predicting in®ltration of water into a frozen soil. The simulation is based on the continuity, energy and momentum equations, and uses well-known and accepted procedures to de®ne the transport phenomena and the thermophysical properties of frozen soil. A parametric equation describing the variation in cumulative in®ltration with time during quasi-steady-state ¯ow in medium-and ®ne-textured soils is presented. The expression relates in®ltration to initial soil saturation, soil surface saturation, soil hydraulic conductivity, initial soil temperature and in®ltration opportunity time. In®ltration estimates by the expression demonstrate reasonable agreement with those determined by ®eld measurement.
