Abstract (en)
[origin: WO2014056541A1] The present invention concerns a method for monitoring the thickness of soil (6) between a soil surface (8) and a device (4) buried in said soil (6), possibly underwater, the device (4) comprising at least one heat source (1), the method comprising steps of (i) measuring at least one temperature using at least one temperature sensing element (3) located in the vicinity of the heat source(s) (1), and (ii) calculating an estimated soil thickness using a pre-determined thermal distribution function (20) which links measured temperatures and soil thickness. The present invention concerns also an instrumented device (4) and a system implementing the method.
