The subsurface thermal regime is affected by fluctuations of ground surface temperature (GST) as well as by groundwater flow. Thermal anomalies produced by groundwater flow interact with those caused by downward conductive heat transfer in response to ongoing surface warming. Due to complexity related to this coupling in diverse environments and across a range of spatiotemporal scales, their coupled effect is generally ignored when interpreting borehole-depth temperature profiles. Through the development of more advanced models, the objective of this project is i) to coupled effects of ground surface temperature (GST) changes, topography, and lithology variations to investigate the individual contributions of conductive and advective heat transport processes, and ii) to link the forward model with a suitable multi-borehole inversion scheme to allow the decomposition of the measured temperature signal, namely the separation of the effects of fluid flow and of past ground surface temperature (GST) variations, which is a necessary step towards understanding the role of groundwater flow on temperature distributions at catchment scales.
