The Application Of Shallow Geothermal Exploration Methods To Detect High Permeability Features In Groundwater Flow Systems

An exploration method using shallow soil temperature<br>measurements as an exploration tool to find permeable bodies at<br>depth in an impermeable matrix is described. The depth of seasonal<br>soil temperature variation is discussed. A method of measuring<br>soil temperatures below the depth of seasonal variation is<br>described. Simple finite difference modeling techniques to predict<br>thermal anomaly characteristics are presented. Case histories are<br>presented which demonstrate the application of the method for<br>groundwater.
