A Tool for Processing and Inversion of MASW Data and a Study of Inter-session Variability of MASW
Geotechnical Testing JournalABSTRACT Multichannel analysis of surface waves (MASW) is a noninvasive active-source technique for determination of near-surface shear wave velocity (VS) profiles. Here we introduce and describe MASWavesPy, an open-source Python package for processing and inverting MASW data, whose design follows an object-oriented paradigm.
