Fusion of information from geophysical and geotechnical investigations for levee assessment

The identification of levees constitutive materials, as well as the detection of possible interfaces and anomalies, are crucial for site characterization. During investigation campaigns, complementary geophysical and geotechnical methods are usually used. These two sets of methods yield data with very different spatial scales and different levels of incompleteness, uncertainty and inaccuracy. On the one …
