Abstract

Rain affects the thermal properties of soil and the temperature of soils and buried targets in the penetration depth of the water. This work involves using predictions from the Countermine Computational Test Bed, (CTB), a 3-D finite element model that accounts for coupled heat and moisture transfer in soil and targets. The meteorological data set used in this work is one day of a meteorological data set, repeated over 3 days. The repeated meteorological data set is required to isolate the effects of rain. The CTB is used to predict and compare surface and subsurface soil and target temperatures with and without rain. The meteorological data set contains 24hrs without rain, followed by 14 hrs of rain at a precipitation rate of 5 mm/hr, then 10 hours plus 1 subsequent day without rain and with no cloud cover.
