The surface‐wave method using a multistation approach is a powerful field test as it is fast, robust and cost‐effective for geotechnical zonation of large areas. A case study is presented to illustrate the application of the method for the geotechnical characterization of an area located at Póvoa de Santa Iria, where Miocene bedrock is covered by thick Quaternary terraces and soft alluvial deposits. The results are analysed along with other relevant data: boreholes with standard penetration test data, resonant‐column tests on undisturbed samples and other available geological and geotechnical data.
