| 摘要 |
A system for monitoring level variations of at least one bottom region of a soil subjected to erosive and sedimentary agents, which comprises at least one monitoring element (15) fastened to said bottom, said at least one monitoring element (15) comprising sensor means for detecting a response of said at least one monitoring element (15) with respect to a stress. Said stress is a stress able to determine vibrations originating displacements of at least part of said at least one monitoring element, said response is a function of said displacements of at least part of said at least one monitoring element (15) and means (150) are provided for analysing said response with respect to a stress, identifying characteristic frequencies and correlate said characteristic frequencies with a lowering of said bottom region (20). |
