Thermal conductivity groundwater flow

The physics of thermal conduction and storage are, in fact, directly analogous to those of groundwater flow. Thermal conductivity (kT) and hydraulic conductivity (k) are analogous, as are heat capacity and storage coefficient and temperature (7) and hydraulic head (h). Indeed, heat flow (H) is estimated by an analogous equation to Darcy s Law ... 

The flow of groundwater in a sedimentary basin results from the combined influence of the different driving forces for groundwater flow (mechanical, thermal, chemical and electrical driving forces) and the hydraulic conductivity of the subsurface. The transport of grovmdwater, heat and electricity, the mass transport of chemical components and the deformation of the solid part of the subsurface are coupled processes. 

Moreover, coupled thermal and hydraulic analysis in the far field is conducted using the homogenized parameters and the heat flux from the near field. This series of simulations shows that it is necessary to consider the effects of coupled processes in the near field on the regional groundwater flow system.
