Some practical applications of shear wave velocity measurements in dense sand [PDF]
E3S Web of ConferencesShear wave velocity (Vs) profiles were obtained using two techniques at a dense sand site in Blessington near Dublin, Ireland. It was shown that both the multichannel analysis of surface waves (MASW) and seismic CPT (SCPTU) techniques provided reliable ...

Structure of an Ancient Egyptian Tomb Inferred from Ground-Penetrating Radar Imaging of Deflected Overburden Horizons [PDF]
, 2015 Geophysical data acquisitions in most archaeological campaigns aim to image the target structure directly. The presence of a target, however, may be inferred from its interaction with surrounding layers, if its relationship with those layers can be ...
