Rescaling of incorrect source strength using Marchenko Redatuming

The iterative Marchenko scheme is a recent development in the field of Geophysics and a way to retrieve Green's functions at any point in the subsurface, called a focal point. To achieve this, only the reflection response measured at the Earth's surface and an estimation of the first arrival at the focal point are required. If the amplitude of...

Influence of multiple thin soft layers on the cone resistance in intermediate soils

In this thesis research is presented on the influence of multiple thin soft layers on the cone resistance and an attempt has been made to develop a correction factor from numerical and physical models. The presence of thin layers causes difficulties with determination of the liquefaction potential of sand deposits containing thin clay layers...
