In this study a geophysical investigation using multi-channel surface wave measurements (MASW) was undertaken to characterize the condition of earth levees. The field measurements were conducted on Vistula levees near Kraski Górne. The MASW method allowed mapping shear wave velocity structures along levees and so relatively high and low velocity zones in the levee body could be easly read. The results were compared to borehole drillings and DPL test. As a conclusion it can be said that the MASW method can be used to identify failure risks areas with a relatively high resolution.
