Temporal variations of spring water temperatures in relation to the extents of the heat transport modes occuring in the karstified lower Gypsum-Keuper aquifer (Karnian, southern Germany).

Abstract:
The importance of different heat transport modes was studied by analysis of the temporal sequences of spring water temperatures in a karstic aquifer. For the aquifer with a horizontal groundwater flow and flow velocities of more than 100 m year"SUP-1", model calculations indicate that horizontal heat transport in the aquifer occurs predominantly by convection. For vertical heat transport from the earth's surface, conduction and convection are implicated in varying degrees; in order to indicate these, the temporal series of the spring water temperatures were separated into their conductively and convectively components. Generally this can yield valuable information about the properties of thin surface-near aquifers. Thus, the quantification of a heat component transported vertically by convection into the aquifer can provide evidence of hydraulic conductivities as potential infiltration routes for contaminants.
