Analyzing the thermal conductivity of soil as a function of other parameters is necessary to understand the flow of heat around the earth-to-water heat exchanger. Thermal conductivity depends on several parameters, including soil composition, water content, compaction level, and porosity. The effect of the above parameters on thermal conductivity was investigated through laboratory studies. Samples were collected at a depth of 2 meters below ground level from an area located within the American University of Sharjah Campus. The thermal conductivity of the prepared specimens was measured using a C-Therm Technologies analyzer. The results indicate that increasing the water content and dry density increase the thermal conductivity of the soil. However, it was noticed that the initial water has a higher effect on thermal conductivity than the initial dry density. Additionally, it was found that porosity affects the hydraulic conductivity of the sand. The results of this study can be used to investigate the geothermal potential in the GCC region further.
