Testing of Soil Heat and Water Flow Models

The SHAW model ( Simultaneous Heat And Water ) is tested with water content and temperature profile data for a soil located near Rosemount Minnesota. The predicted frost/thaw depth, soil water content, and temperature at depths of 10, 20, 40, 80, and 100 cm are compared to measured values. The results show that the prediction of frost depth and temperature profile agree well with measured field data, while agreement between measured and predicted liquid water content is not as good.
