Thermal field methods of the shallow subsurface

Temperature is one major physical quantity of the subsurface and therefore, heat can be used as a tracer. This thesis further promotes heat as a tracer by evaluating a thermal tracer test and comparing the obtained results to previous studies. Additionally, a new thermal field test for the hydraulic characterization of the subsurface is developed. This new development transfers the thermal response test, to a powerful hydrogeological field test, by introducing a new evaluation approach.
