River embankment characterization: The combined using geophysical and geotechnical techniques

River embankment characterization: The combined using geophysical and geotechnical techniques

Abstract

Previous ton activities in north Italy (especially in the Veneto area) has brought river embankments in to the focus of general public focus. Many of these embankments tend to be more than a century older and then have become continuously restored, to make sure that more information on their existing framework is typically missing. The track of these frameworks is now centered, generally, on graphic evaluation and localised measurements associated with the embankment material variables. But this monitoring is generally insufficient assure a satisfactory security stage against floods. Therefore there is certainly an increasing interest in smooth and accurate study strategies, particularly geophysical techniques. These tips can provide more information throughout the subsurface buildings, tend to be non-invasive, cost-efficient, and quicker than standard techniques. But needed verification so that you can incorporate dependable outcome, specifically in complex and reworked man-made tissues such as embankments. Within paper we found an incident research wherein three different geophysical strategies have already been http://datingmentor.org/gay-dating/ applied: electric resistivity tomography (ERT), frequency website electromagnetic induction (FDEM) and soil Penetrating Radar (GPR). Two test web sites have now been selected, both found in the Province of Venice (NE Italy) where in actuality the Tagliamento River enjoys huge embankments. The results gotten with your method happen calibrated against evidence resolving from geotechnical investigations. The good qualities and downsides of every strategy, as well as their family member merit at determining the particular popular features of the embankments in this region, are showcased. The outcome demonstrate that geophysical tips can offer very useful facts for embankment characterization, so long as the data explanation try constrained via immediate research, albeit restricted in area.
