Abstract: An experimental study was conducted in an indoor soil tank, to examine
low-temperature infiltration and movement through unsaturated soil in topsoil layer of riparian
zone. Low-temperature water infiltration tests were carried out at three different heads in the
filling fine sand. Infiltration process, moisture and temperature fields were continuously
monitored and analyzed to study the impacts of the water head, the infiltration parameters, and
moisture and temperature fields. Results showed that the higher the infiltration head, the greater
is the vertical (horizontal) migration distance of the wetting front. The migration velocity of the
vertical wetting front also gradually decreased with increasing infiltration time, and becoming
more and more stability at the end. Infiltration rater had the larger fluctuations at the head of 5
cm and the settling time is greater than the head of 25 cm and 45 cm. The higher the infiltration
head, the faster is the decreasing rate of average temperature before the temperature fields
could go into a relatively steady status. At the head of 25 cm, infiltration of the low temperature
water basically reached steady status after 420 min and the head of 45 cm is after 240 min.
