For river embankment characterization non-invasive geophysical investigations are a valuable complementary tool to standard geotechnical testing. To this aim, resistivity and seismic methods are often adopted and can offer complementary information with respect to pore fluid properties and solid skeleton characteristics, respectively. The use of streamer cables for these surveys can reduce the acquisition times, making geophysical investigations ideal for preliminary screening. Few examples of combined seismic and electric streamer systems were already proposed in the literature, but their applicability for long and extensive surveys still need to be demonstrated. Moreover, tailored processing and interpretation methods are necessary given the large amount of data collected with such systems, which can be challenging for standard processing and inversion software.</p> <p>We present a dataset of a 4 km combined seismic and electric streamer survey acquired along the embankment of the Po River in Crescentino, near Torino, in north-west Italy. Data acquisition strategies are discussed and preliminary data analyses are reported. The survey demonstrated the efficiency and potentiality of combined seismic and electric streamer systems in investigating river embankments. All the acquired geophysical data, together with complementary geotechnical and topographic information, are made available in a structured dataset (<a href="https://doi.org/10.5281/zenodo.18183049" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.18183049</a>). The presented dataset can be an ideal playground to test and benchmark alternative processing and interpretation approaches, and enable an advancement in the state-of-the-art of these characterization methodologies.
